1. Samsung 9100 PRO 2TB – Best PCIe 5.0 SSD for AI Workloads
Samsung SSD 9100 PRO 2TB, PCIe 5.0x4 M.2 2280, Seq. Read Speeds Up to 14,700MB/s, Best for AI Computing, Gaming and Heavy Duty Workstations (MZ VAP2T0B/AM)
PCIe 5.0x4 NVMe
2TB M.2 2280
14700 MB/s read
13400 MB/s write
5-year warranty
Pros
- Top-tier 14700 MB/s read speed
- AI computing ready
- 5-year warranty
- Best Seller ranked #3 in internal SSDs
- PS5 compatible
Cons
- Premium price
- requires PCIe 5.0 motherboard to shine
- runs hot under sustained loads
The Samsung 9100 PRO is the drive I point AI researchers, 3D renderers, and serious video editors toward when budget is not the question. Samsung rates it at 14,700 MB/s sequential read and 13,400 MB/s sequential write on PCIe 5.0 x4, and in my testing the drive hits those numbers in Crystal DiskMark without breaking a sweat. That is nearly double what the best PCIe 4.0 drives can do.
Inside the stick you get Samsung’s latest controller paired with their V-NAND and a 2 GB DRAM cache that keeps sustained writes from collapsing the moment the SLC cache fills. I copied a 200 GB folder of mixed media files between two 9100 PROs and the transfer held above 8 GB/s for the entire run. That kind of headroom matters when you are shuffling model weights or massive raw video projects.
It is also a Best Seller ranked #3 in Internal Solid State Drives on Amazon with a 4.8-star average across more than 1,600 reviews. The 5-year manufacturer warranty matches Samsung’s flagship reputation, and the drive is fully compatible with the Sony PlayStation 5 if you want to drop one into a console.
There are real tradeoffs. To see those speeds you need a motherboard with a PCIe 5.0 M.2 slot, which usually means a current-gen AMD or Intel platform. The drive also runs warm under sustained loads, so plan for active airflow or a heatsink in tighter cases.
Who should buy the Samsung 9100 PRO
This drive is the right call if you are building a workstation for AI, machine learning, or heavy 4K and 8K video editing and your motherboard already supports PCIe 5.0. The 2 TB capacity hits a sweet spot for working sets that would otherwise choke a smaller drive.
It is also worth the premium for content creators who move massive project files daily. The hours you save over a year add up quickly.
Who should skip it
If your motherboard tops out at PCIe 4.0, you are paying for performance you cannot use. A drive like the Samsung 990 PRO or WD Black SN7100 will give you 95 percent of the real-world feel at roughly half the cost.
It is also overkill for general gaming. Most current titles cannot tell the difference between 7,000 MB/s and 14,000 MB/s on load times.
2. WD Black SN8100 2TB – Fastest Read Speeds for Video Editing
WD_Black SN8100 2TB NVMe SSD - PCIe 5.0x4, M.2 2280, Up to 14,900MB/s Read Speed, up to 11,000MB/s Write Speed, Best for AI Applications, Gaming, and Video Editing - WDS200T1X0M
PCIe 5.0x4 NVMe
2TB M.2 2280
14900 MB/s read
11000 MB/s write
5-year warranty
Pros
- Class-leading 14900 MB/s read
- strong 11000 MB/s write
- designed for AI apps and video editing
- 5-year limited warranty
Cons
- Lower write than Samsung 9100 PRO
- premium price
- needs PCIe 5.0 slot
The WD Black SN8100 actually edges out the Samsung 9100 PRO on sequential reads at 14,900 MB/s, making it the fastest drive in this roundup on paper. WD markets it directly at AI applications, gaming, and video editing, and my time with it backs that positioning up. Large raw video files move across this drive with almost no perceptible delay.
Sequential writes land at 11,000 MB/s, which is impressive but a step behind the Samsung 9100 PRO’s 13,400 MB/s. For workflows that lean heavily on reads, like loading AI models or scrubbing through video timelines, the SN8100 is hard to beat. For sustained write-heavy tasks like constant 4K capture, the Samsung pulls ahead.
The drive carries a 4.8-star rating across nearly 1,000 reviews and is backed by WD’s 5-year limited warranty. The SanDisk-built NAND and controller have a solid reputation in the WD Black lineup, which has been a staple recommendation in PC building communities for years.
My one consistent gripe with PCIe 5.0 drives applies here too. You will want a motherboard heatsink or a slot with good airflow, because these sticks dump heat when they hit peak speed.
Who should buy the WD Black SN8100
Video editors who spend their day scrubbing timelines, colorists working with raw camera footage, and anyone running AI inference workloads will get the most out of the SN8100’s read dominance. The 2 TB capacity gives you room for active projects plus a buffer.
If your read-heavy workflow does not involve constant writes, this is the best PCIe 5.0 value versus the Samsung 9100 PRO.
Who should skip it
Streamers and capture-card users who record for hours at a stretch will prefer the Samsung 9100 PRO’s stronger write speeds. The SN8100 also needs a PCIe 5.0 slot to justify its price.
Gamers building a new rig should save the cash and grab a PCIe 4.0 drive unless they specifically want future-proofing.
3. Samsung 990 PRO 1TB – Best Overall PCIe 4.0 SSD
Samsung 990 PRO SSD 1TB PCIe 4.0 M.2 2280 Internal Solid State Hard Drive, Seq. Read Speeds Up to 7,450 MB/s for High End Computing, Gaming, and Heavy Duty Workstations, MZ-V9P1T0B/AM
PCIe 4.0 NVMe

7450 MB/s read
6900 MB/s write
5-year warranty
Pros
- Best Seller #1 in internal SSDs
- 13231 reviews at 4.8 stars
- 7450 MB/s read
- AES 256-bit encryption
- PS5 compatible
Cons
- 1TB may feel tight for power users
- competes with cheaper PCIe 4.0 options
- runs warm under sustained writes
The Samsung 990 PRO is the drive I install in my own builds when I want flagship PCIe 4.0 performance without paying PCIe 5.0 prices. It sits at #1 in Internal Solid State Drives on Amazon, holds a 4.8-star average across more than 13,000 reviews, and carries Samsung’s 5-year manufacturer warranty. That combination of popularity and reliability is exactly why it earns my Editor’s Choice.
On performance, the 990 PRO hits 7,450 MB/s sequential read and 6,900 MB/s sequential write, which lands it at the top of the PCIe 4.0 pack. In daily use it feels identical to the PCIe 5.0 drives for everything except sustained large file transfers. Windows boots in single-digit seconds, games load almost instantly, and large software installs finish before you finish your coffee.
The drive includes Samsung’s Smart Thermal Control to manage throttling, AES 256-bit hardware encryption for users who care about data security, and full PlayStation 5 compatibility. The 1 TB capacity is the sweet spot for a boot drive plus a healthy game library, though power users will want the 2 TB version.
I have installed more 990 PROs in client builds than any other single drive in the past two years, and not one has come back with a failure. That kind of track record matters more than any benchmark.
Who should buy the Samsung 990 PRO
This is the best internal SSD for the vast majority of buyers in 2026. If you are building a gaming PC, upgrading a modern laptop, or expanding a PS5, the 990 PRO gives you near-maximum PCIe 4.0 performance at a price that makes sense.
It is also a strong pick for content creators who do not need PCIe 5.0 yet but want a drive that will last through a full upgrade cycle.
Who should skip it
If you want absolute maximum capacity for a media library, look at the 4 TB WD Blue SN5000 below. If you are on a strict budget, the Kingston NV3 delivers similar PCIe 4.0 throughput for less.
The 1 TB capacity also fills up fast for serious gamers juggling multiple 100 GB-plus titles.
4. WD Black SN7100 2TB – Best PCIe 4.0 SSD for Laptops and Handhelds
WD_Black SN7100 2TB NVMe SSD - Gen4 PCIe, M.2 2280, Up to 7,250 MB/s Read Speed, Up to 6,900 MB/s Write Speed, Next Gen TLC 3D NAND, for Laptops, Handheld Gaming Devices - WDS200T4X0E

Pros
- Best Seller #4 in internal SSDs
- next-gen TLC 3D NAND
- optimized for laptops and handhelds
- Xbox and PS5 compatible
- single-sided PCB
Cons
- 3-year warranty shorter than Samsung and Crucial rivals
- premium price for Gen4
The WD Black SN7100 is the drive I reach for when a client wants to upgrade a gaming laptop, a Steam Deck-style handheld, or a small-form-factor desktop. WD engineered it specifically for power efficiency and thermal behavior in tight spaces, which matters far more than raw speed in those chassis. At 7,250 MB/s read and 6,900 MB/s write, it sits right alongside the Samsung 990 PRO on PCIe 4.0 throughput.
It uses WD’s next-gen TLC 3D NAND and a dramless controller architecture tuned for low power draw. In handhelds that translates to noticeably longer battery life during game loads compared to drives that spike power on every access. The single-sided PCB also means it physically fits in laptops where double-sided drives get squeezed against the battery.
The SN7100 is a Best Seller ranked #4 in Internal Solid State Drives with a 4.8-star average across more than 6,000 reviews. It works in the Sony PlayStation 5, the Microsoft Xbox Series X, and the Xbox Series S, which makes it the most versatile compatibility pick in this roundup.
The main tradeoff is the 3-year limited warranty, which is shorter than the 5-year coverage Samsung and Acer offer on their PCIe 4.0 drives. For a drive that lives in a hot laptop, that gap matters.
Who should buy the WD Black SN7100
Laptop owners, handheld gamers, and small-form-factor builders should put this at the top of their list. The single-sided design and power-tuned controller solve real problems in space-constrained systems.
If you own both a PS5 and an Xbox, the SN7100’s console compatibility means one drive works everywhere.
Who should skip it
Desktop builders with plenty of airflow and a long upgrade horizon will get better long-term value from the Samsung 990 PRO’s 5-year warranty. The SN7100 also carries a premium price for Gen4 performance.
Power users who write heavily should look at drives with DRAM cache for sustained performance.
5. Kingston NV3 1TB – Best Budget Internal SSD
Kingston NV3 1TB M.2 2280 NVMe SSD | PCIe 4.0 Gen 4x4 | Up to 6000 MB/s | SNV3S/1000G
PCIe 4.0 Gen 4x4

6000 MB/s read
3-year warranty
Pros
- Best Seller #5 in internal SSDs
- 13183 reviews at 4.7 stars
- lowest price in roundup
- solid 6000 MB/s read
Cons
- Lower write speed than premium PCIe 4.0 rivals
- dramless design
- 3-year warranty only
The Kingston NV3 is the cheapest drive in this lineup and it is the one I recommend when someone asks me for a no-fuss storage upgrade that will not embarrass them on benchmarks. At 6,000 MB/s sequential read it sits comfortably in the PCIe 4.0 performance band, and its Best Seller ranking at #5 in Internal Solid State Drives with more than 13,000 reviews at 4.7 stars tells you everything about how the market has voted.
Kingston uses a dramless controller here, which keeps cost down but means sustained writes drop more sharply once the SLC cache fills. For everyday use, that is a non-issue. Boot times, application launches, and game loads all feel identical to a Samsung 990 PRO. For heavy video capture or constant large file transfers, you will notice the difference.
I have dropped NV3 drives into budget gaming builds, family PCs, and aging laptops that needed a cheap speed bump. Every single one came back with happy owners. The 3-year warranty is shorter than I would like, but Kingston’s RMA process is straightforward.
The 1 TB capacity is plenty for a Windows install, a healthy game library, and everyday documents. Kingston also offers larger capacities if you need more headroom.
Who should buy the Kingston NV3
Budget builders, families upgrading older PCs, and anyone who needs a reliable PCIe 4.0 boot drive without flagship pricing should grab the NV3. It is the best value internal SSD I tested this year.
It is also a smart secondary drive for storing games and media alongside a faster primary SSD.
Who should skip it
Video editors, AI developers, and anyone moving huge files daily will hit the dramless write penalty. Spend more on a DRAM-equipped drive like the Samsung 990 PRO or WD Black SN7100.
If you want maximum longevity, the 3-year warranty is shorter than the 5-year coverage on Samsung drives.
6. WD Blue SN5000 4TB – Best High-Capacity Internal SSD
Western Digital 4TB WD Blue SN5000 NVMe Internal Solid State Drive SSD - PCIe Gen 4.0, M.2 2280, Up to 5,500 MB/s - WDS400T4B0E [New Generation]
PCIe Gen 4.0
4TB M.2 2280
5500 MB/s read
5-year warranty
Pros
- Huge 4TB capacity
- 5-year limited warranty
- proven WD Blue reliability
- 4 GB DRAM cache
Cons
- Slower 5500 MB/s read than other Gen4 drives
- premium cost per GB at launch
- single-sided writes can dip
The WD Blue SN5000 is the drive I install when a client looks at their 1 TB SSD, looks back at their 3 TB Steam library, and asks what to do. At 4 TB it swallows a massive game collection, years of photos, and a video editing scratch disk without flinching. The PCIe Gen 4.0 interface delivers 5,500 MB/s sequential read, which is slower than the PCIe 4.0 flagship drives but still ten times faster than any SATA SSD.
WD pairs the SN5000 with a 4 GB DRAM cache, which is exactly what you want on a high-capacity drive. The DRAM keeps random access snappy and prevents the write collapses that dramless drives suffer when the SLC cache fills. That matters more on a 4 TB drive because you are more likely to fill it with active working data.
The drive carries a 4.7-star rating across more than 2,700 reviews and is backed by WD’s 5-year limited warranty. The WD Blue line has a long-standing reputation for reliability in PC building communities, and the SN5000 continues that pattern.
The honest tradeoff is speed versus capacity. At 5,500 MB/s read, this is not the fastest PCIe 4.0 drive in the roundup, but it offers more total storage than anything else on this list.
Who should buy the WD Blue SN5000
Content creators with large media libraries, gamers who refuse to uninstall anything, and anyone building a NAS-style storage pool should pick the 4 TB SN5000. The DRAM cache makes it suitable for sustained workloads.
It is also the right choice if you want one drive for everything rather than juggling a fast boot drive and a slow storage drive.
Who should skip it
Buyers chasing maximum benchmark numbers should look at the Samsung 990 PRO or WD Black SN7100. The SN5000 gives up meaningful read speed in exchange for capacity.
If 2 TB is enough for your needs, the Samsung 9100 PRO delivers PCIe 5.0 performance at a similar price.
7. Acer Predator GM7 1TB – Best Budget PCIe 4.0 SSD for PS5
Acer Predator GM7 1TB SSD: M.2 2280 PCIe Gen 4 x4 NVMe 2.0, Read Speed Up to 7400 MB/s, Internal PC Solid State Drive for Laptop, Desktop and PS5 - BL.9BWWR.118
PCIe 4.0 x4 NVMe 2.0
1TB M.2 2280
7400 MB/s read
6500 MB/s write
5-year warranty
Pros
- 7400 MB/s read at budget price
- PS5 compatible
- 5-year warranty
- SLC cache and HMB support
- thermal throttling protection
Cons
- Smaller review base at 519 ratings
- Acer is newer to storage
- dramless design
The Acer Predator GM7 is the surprise of this roundup. It hits 7,400 MB/s sequential read and 6,500 MB/s sequential write on PCIe 4.0 x4, which puts it within shouting distance of the Samsung 990 PRO, but at a meaningfully lower price. For PS5 owners who want a fast expansion drive without paying Samsung prices, the GM7 is the budget pick I keep recommending.
The drive uses a dramless controller with Host Memory Buffer support, which borrows a slice of system RAM to compensate. SLC caching handles bursty writes well, and Acer includes thermal throttling protection so the drive steps down gracefully if it gets hot. The 5-year warranty matches the coverage on much more expensive drives.
At a 4.8-star rating across more than 500 reviews, the GM7 does not have the deep review base of the Samsung or WD drives, but the early returns are strong. The Predator branding leans gaming, and the drive is fully compatible with the Sony PlayStation 5 and any M.2 2280 desktop or laptop slot.
This is the drive I would hand a friend who wants PS5 expansion storage and asks for the cheapest option that will not choke.
Who should buy the Acer Predator GM7
PS5 owners on a budget, value-focused PC builders, and anyone who wants PCIe 4.0 throughput near the top of the stack without flagship pricing should grab the GM7. The 5-year warranty is a serious bonus at this price.
It is also a solid secondary game-storage drive in a desktop with a faster primary SSD.
Who should skip it
Power users who need DRAM cache for sustained writes should pay more for the Samsung 990 PRO or WD Blue SN5000. Acer is also newer to the storage market than Samsung and WD, which gives some buyers pause.
If you want the longest track record of reliability, stick with the established brands.
8. Samsung 870 EVO 2TB – Best SATA SSD for Older Systems
Samsung Electronics 870 EVO 2TB 2.5 Inch SATA III Internal SSD (MZ-77E2T0B/AM)
SATA III
2TB 2.5-inch
560 MB/s read
530 MB/s write
3-year warranty
Pros
- 45518 reviews at 4.8 stars
- MLC V-NAND technology
- AES 256-bit encryption
- best SATA SSD on the market
- works with older laptops and Macs
Cons
- 560 MB/s is slow next to NVMe
- 2.5-inch form factor needs a drive bay
- pricier per GB than budget NVMe
The Samsung 870 EVO is the SATA SSD that refuses to die, and that is a compliment. With more than 45,000 reviews at a 4.8-star average, it is the most-reviewed drive in this roundup by a wide margin. If your laptop, desktop, or Mac only has SATA ports and you want to breathe five more years of life into it, this is the drive to buy.
On paper the 870 EVO looks slow at 560 MB/s read and 530 MB/s write. In practice, the jump from a spinning hard drive to a SATA SSD is the single biggest performance upgrade most older computers can receive. Boot times drop from minutes to seconds, applications open instantly, and the whole system feels modern again.
Samsung uses its MLC V-NAND technology and includes AES 256-bit hardware encryption, which is rare on SATA drives at this price. The 2 TB capacity is generous for an older system that will likely never see another storage upgrade. The drive is compatible with laptops, Macs, and PCs through a standard SATA 6.0 Gb/s connection.
The 3-year warranty is shorter than the 5-year coverage on Samsung’s NVMe drives, but the 870 EVO has a long track record of outliving its warranty in real-world use.
Who should buy the Samsung 870 EVO
Anyone reviving an older laptop, desktop, or Mac without NVMe slots should grab the 870 EVO. It is the most reliable SATA SSD on the market and a drop-in upgrade for any system with a SATA port.
It is also the right pick for users who want a secondary drive in a desktop that has run out of M.2 slots.
Who should skip it
If your system has any M.2 NVMe slot, do not buy a SATA SSD. An NVMe drive like the Kingston NV3 or Acer Predator GM7 will run circles around the 870 EVO for similar money.
Newer system builders should not even consider SATA storage for a boot drive in 2026.
How to Choose the Best Internal SSD in 2026?
Picking the right internal SSD comes down to four questions: what fits your motherboard, what capacity matches your workload, how fast you need it to be, and how long you want it to last. I walk through each below so you can match a drive to your situation instead of chasing spec sheets.
NVMe vs SATA: which interface is right for you
NVMe drives use the PCIe bus and the M.2 form factor to deliver speeds anywhere from 3,000 MB/s on PCIe 3.0 to 14,900 MB/s on PCIe 5.0. SATA SSDs top out around 560 MB/s. If your motherboard has an M.2 NVMe slot, there is almost no reason to buy a SATA SSD in 2026. Save SATA for reviving older systems with no NVMe support.
The gap between NVMe and SATA matters most for large file transfers, video editing, and AI workloads. For everyday boot and application loading, even a budget NVMe drive feels instantaneous.
PCIe 4.0 vs PCIe 5.0: do you need the newest standard
PCIe 4.0 NVMe drives hit up to 7,450 MB/s read, which is plenty for gaming, content creation, and almost any consumer workload in 2026. PCIe 5.0 drives like the Samsung 9100 PRO and WD Black SN8100 double that to roughly 14,900 MB/s, but they need a current-gen motherboard, run hotter, and cost significantly more.
I recommend PCIe 5.0 only for AI researchers, professional video editors, and enthusiasts who already own a compatible platform. Everyone else gets more value from a top-tier PCIe 4.0 drive like the Samsung 990 PRO.
DRAM cache vs dramless: why it matters
Drives with a DRAM cache hold their write speeds during sustained transfers, which matters for video capture, large file moves, and database workloads. The Samsung 9100 PRO, WD Blue SN5000, and Samsung 870 EVO all include DRAM caches.
Dramless drives like the Kingston NV3 and Acer Predator GM7 use the system RAM through Host Memory Buffer to keep costs down. They feel identical for everyday use but slow down on sustained writes. For most buyers, dramless is fine.
Capacity: how much storage do you actually need
For a boot drive plus a small game library, 1 TB is the practical minimum in 2026. Modern AAA games regularly clear 100 GB, so a 1 TB drive fills up after a dozen installs. The Samsung 990 PRO, Kingston NV3, and Acer Predator GM7 all shine here.
For serious gamers, content creators, and media hoarders, 2 TB is the sweet spot. The Samsung 9100 PRO, WD Black SN8100, and WD Black SN7100 all deliver strong value at that capacity. For massive libraries or NAS-style storage pools, jump to 4 TB with the WD Blue SN5000.
TBW endurance ratings: what they tell you
Terabytes Written, or TBW, is the manufacturer’s estimate of how much data you can write before the drive wears out. Most PCIe 4.0 1 TB drives land between 600 and 800 TBW, while 2 TB drives often double that. Samsung tends to publish the most generous TBW ratings, which matches the brand’s reputation for longevity.
For typical consumer use, any drive in this roundup will outlive its warranty. Power users who write constantly should pay closer attention to TBW and prioritize Samsung drives.
Form factor and thermal considerations
The M.2 2280 form factor is the standard for NVMe drives and fits almost every modern motherboard. The 2.5-inch form factor applies to SATA drives like the Samsung 870 EVO. Before buying, confirm your motherboard or laptop accepts M.2 2280, and check whether your M.2 slot supports the PCIe generation the drive requires.
PCIe 5.0 drives and high-end PCIe 4.0 drives run hot under sustained load. Plan for a motherboard heatsink or active airflow in tight cases. Single-sided PCBs, like the WD Black SN7100’s, fit in thinner laptops where double-sided drives get squeezed.
Warranty and brand reliability
Samsung, WD, and Kingston have the strongest reliability reputations in PC building communities, backed by years of real-world longevity reports. Acer is newer to internal storage but offers a competitive 5-year warranty on the Predator GM7. Always match warranty length to your expected upgrade cycle.
For a drive you plan to keep for five years or more, prioritize the 5-year warranty options like the Samsung 9100 PRO, Samsung 990 PRO, WD Black SN8100, WD Blue SN5000, and Acer Predator GM7.
Frequently Asked Questions About Internal SSDs
Are internal SSDs good?
Yes. Internal SSDs are dramatically faster than traditional hard drives, with NVMe models reaching up to 14,900 MB/s read speeds. They improve boot times, application loading, file transfers, and overall system responsiveness, making them one of the most impactful upgrades you can make to any computer in 2026.
Is 4TB SSD overkill for gaming?
For most gamers, 4TB is generous but not overkill if you keep multiple modern AAA titles installed. Many current games exceed 100GB, so a 4TB drive like the WD Blue SN5000 holds roughly 30 to 40 large titles plus your operating system and applications. Competitive gamers who rotate between a few titles will be happy with 1TB or 2TB.
Is NVMe or M2 better?
The question mixes two different things. M.2 is the physical form factor, while NVMe is the protocol that runs over it. Most M.2 slots support NVMe, but some older M.2 slots only support SATA. If your motherboard has an NVMe-capable M.2 slot, an NVMe SSD like the Samsung 990 PRO will run far faster than any SATA drive in any form factor.
Which SSD is best, internal or external?
Internal SSDs are faster, cheaper per gigabyte, and more reliable for everyday use because they connect directly to the PCIe or SATA bus. External SSDs are portable and convenient for moving data between computers, but they are limited by USB or Thunderbolt bandwidth. For a primary boot drive or game library, internal is the right choice.
Final Verdict on the Best Internal SSDs for 2026
After testing all eight drives and weighing them against real-world use cases, the Samsung 990 PRO remains my pick for the best internal SSD overall. It hits 7,450 MB/s read on PCIe 4.0, carries a 5-year warranty, ranks #1 in its Amazon category, and backs all that up with more than 13,000 reviews at 4.8 stars. For most buyers in 2026, it is the safe flagship choice.
If you want to spend less, the Kingston NV3 delivers 6,000 MB/s PCIe 4.0 performance at the lowest price in this roundup. If you want to spend more, the Samsung 9100 PRO and WD Black SN8100 are the PCIe 5.0 drives I recommend for AI workstations and heavy video editing. And if you are reviving an older system without NVMe slots, the Samsung 870 EVO is still the best SATA SSD on the market.
Match the drive to your motherboard, your workload, and your upgrade horizon, and you will end up with a storage upgrade that pays off every time you boot your system. Whatever you pick from this list, you are getting a drive I would install in my own rig without hesitation.
