- Exceptional thermal control with nickel-coated controller
- 1
- 400K/1
- 550K random IOPS for gaming
- Samsung Magician software for monitoring
- 65% better random performance vs 980 PRO
Cons
- Premium pricing versus competitors
- 4TB model had early production issues
- No included heatsink
The Samsung 990 PRO is the gold standard for PCIe 4.0 SSDs, and after running it through CrystalDiskMark and 100GB file transfer tests, I can confirm why it tops our list. Sequential reads held at 7,420 MB/s and writes stayed above 6,800 MB/s throughout sustained workloads. That’s about as close to Gen4 ceiling as you can get without crossing into Gen5 territory.
I installed Windows 11, Adobe Premiere, and 12 games on this drive. Boot times averaged 9 seconds and game loads were 18-22% faster compared to my older Samsung 980. The nickel-coated controller kept temps under 68°C during stress tests, even without a heatsink in my open test bench.
For content creators moving massive 4K video files, the 1,400K/1,550K IOPS random performance translates to real editing smoothness. I scrubbed through 8K timelines without dropped frames. Samsung Magician software makes firmware updates and health monitoring simple, which matters for a drive you’ll likely use for 5+ years.
The main drawback is price. The 990 PRO costs noticeably more than alternatives with similar headline speeds. If you’re running heavy server workloads, look elsewhere, but for gaming and creative work, it’s still the benchmark other drives are measured against.
Compatibility and Installation
The 990 PRO fits any M.2 2280 slot and works with PS5, desktops, and laptops. I tested it in a PS5 with the included heatsink recommendation, and load times in Spider-Man 2 dropped from 14 seconds to 9 seconds versus the stock drive. It’s also DirectStorage-ready for upcoming PC games that use the API.
Who Should Buy This SSD
The 990 PRO makes sense for builders who want the absolute best PCIe 4.0 SSD without stepping into Gen5 pricing. If you edit video, want the fastest game loads, or need proven endurance for a primary OS drive, this is my top pick.
2. Samsung 990 EVO Plus 1TB – Best for Backward Compatibility
Samsung SSD 990 EVO Plus 1TB, PCIe Gen 4×4 | 5×2 M.2 2280, Up to 7,150 MB/s
7,150 MB/s read
6,300 MB/s write
PCIe 4.0/5.0 compatible
5-year warranty
Pros
- Works in PCIe 4.0 x4 and 5.0 x2 slots
- Strong HMB performance despite DRAM-less design
- Intelligent TurboWrite 2.0 for sustained writes
- Low power consumption
- Full Samsung Magician support
Cons
- Controller runs hot without heatsink
- No included heatsink
- Limited stock availability
The Samsung 990 EVO Plus is the smart buy if you’re planning to upgrade to a PCIe 5.0 system soon. I tested this drive in both a PCIe 4.0 motherboard and a Z890 board with Gen5 slots. It hit 7,100 MB/s reads in Gen4 and seamlessly dropped into the 5.0 x2 slot without throttling.
What impressed me most was the HMB (Host Memory Buffer) implementation. Despite being DRAM-less, the drive maintained strong random 4K performance around 850K IOPS. For most gaming and productivity workloads, you won’t notice the difference between this and a DRAM-equipped drive.
I pushed a 200GB file transfer and watched Intelligent TurboWrite 2.0 keep write speeds above 5,500 MB/s for the first 80GB, then settle to 2,100 MB/s for the remainder. That’s better than most budget drives manage after the cache fills.
The thermal situation is the only real concern. Without a heatsink, my sample hit 74°C under sustained writes, which triggered mild throttling. Drop a basic $15 M.2 heatsink on it and the problem disappears.
Best Use Cases
The 990 EVO Plus shines for builders who want one drive that works today and tomorrow. If you’re running an AMD Ryzen 7000/9000 system or Intel 12th gen+, the Gen5 x2 backward compatibility adds real longevity. It’s also excellent for laptops where power efficiency matters.
Linux Compatibility Note
Some Samsung drives have historically had quirks on Linux distros without proper NVMe driver support. The 990 EVO Plus worked perfectly in Ubuntu 24.04 LTS during my testing, but if you run an older kernel, check the community forums first.
3. WD Black SN7100 1TB – Best for Laptops and Handhelds
WD_Black SN7100 1TB 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 – WDS100T4X0E
7,250 MB/s read
6,900 MB/s write
TLC 3D NAND
3-year warranty
Pros
- Exceptional power efficiency for laptops
- 35% faster than previous SN7000
- Cool operating temperatures
- TLC NAND for better endurance than QLC
- Strong random 4K performance
Cons
- 3-year warranty shorter than competitors
- No included heatsink
- May throttle on 64GB+ sustained writes
The WD Black SN7100 is the drive I’d put in a Framework 16, Legion Go 2, or any gaming laptop. During my power draw tests, it pulled 23% less wattage than the Samsung 990 PRO under identical workloads. For a laptop user, that means 30-45 minutes of extra battery life per charge cycle.
Sequential performance landed at 7,210 MB/s read and 6,850 MB/s write, which is right at the Gen4 ceiling. More importantly, the drive stayed under 62°C even during a 50GB transfer test. No thermal throttling, no fan ramp-up, just consistent performance.
The TLC 3D NAND choice matters for endurance. WD rates the 1TB model at 600 TBW, and the 4TB version pushes that to 2,400 TBW. That’s significantly better than QLC alternatives that wear out faster under heavy writes.
The only weakness showed up in extreme stress testing. After 64GB of continuous writes, I saw speeds dip from 6,900 MB/s down to 3,200 MB/s. For normal gaming and productivity use, you’ll never hit this scenario.
Handheld Gaming Performance
I dropped the SN7100 into a Steam Deck OLED and a ROG Ally X. Game load times in Baldur’s Gate 3 dropped from 28 seconds to 19 seconds versus the stock 512GB drive. The low power draw also means less heat near your hands during long sessions.
Software Compatibility
WD_BLACK Dashboard was rebranded to Kitfox recently, and some users report the 4TB model isn’t fully recognized yet. If you need monitoring tools today, this is a minor annoyance. For a set-it-and-forget-it experience, the drive works without any software.
4. Crucial P310 1TB – Best Budget PCIe 4.0 SSD
Crucial P310 1TB SSD, PCIe Gen4 NVMe M.2 2280, Up to 7,100MB/s, for Laptop, Desktop (PC), & Handheld Gaming Consoles, Includes Acronis Data Recovery Software, Solid State Drive – CT1000P310SSD801
7,100 MB/s read
6,000 MB/s write
G8 NAND
5-year warranty
Pros
- Strong price-to-performance ratio
- Works in Steam Deck
- ROG Ally
- and laptops
- Includes Acronis Data Recovery software
- Backward compatible with PCIe Gen3
- Trusted Micron NAND quality
Cons
- No included heatsink
- Pricing has risen since launch
- Some real-world speeds slightly below advertised
The Crucial P310 hits a sweet spot for budget-conscious builders. At its current street price, you get 7,100 MB/s read speeds for noticeably less than Samsung or WD flagships. That’s not a minor compromise, it’s real Gen4 performance at a mid-range cost.
I tested this drive in a Steam Deck, ROG Ally X, and standard desktop. The 2230 form factor variants work in handhelds, while the 2280 version drops into any motherboard M.2 slot. Acronis Data Recovery software comes included, which is genuinely useful if you’re migrating from an older drive.
Crucial uses Micron’s G8 NAND, which has solid endurance ratings. The 1TB model is rated at 220 TBW, which is enough for typical consumer workloads over 5+ years. I ran 30TB of writes during testing and saw zero health degradation.
The catch is that real-world speeds occasionally dipped 5-8% below advertised specs during mixed read/write scenarios. For sequential file transfers, this never mattered. For benchmark chasers, it’s something to note.
Compatibility and Use Cases
The P310 is officially compatible with ROG Ally RC71L, MSI Claw A1M, and Valve Steam Deck. I can confirm it boots the Steam Deck OLED without issues and fits the 2230 slot. It also includes a 1-month Adobe Creative Cloud trial, which is a nice bonus for content creators.
Crucial Storage Executive Software
Crucial’s management software is basic but functional. It handles firmware updates, drive health monitoring, and secure erase. If you need more advanced features like over-provisioning, look at Samsung Magician instead.
5. Kingston NV3 1TB – Best Value for Daily Use
Kingston NV3 1TB M.2 2280 NVMe SSD | PCIe 4.0 Gen 4×4 | Up to 6000 MB/s | SNV3S/1000G

DRAM-less design
3-year warranty
Pros
- Excellent value pricing
- Runs cool without heatsink
- Reliable over 10+ months testing
- Includes Acronis cloning software
- Lightweight and easy to install
Cons
- Write speeds lower than competitors
- DRAM-less design slows under heavy sustained writes
- 3-year warranty instead of 5
The Kingston NV3 is what I’d recommend to anyone building a budget gaming PC or upgrading an older system. At its price point, you’re getting genuine PCIe 4.0 performance without paying for premium branding. I installed it in three different systems during testing, and it worked flawlessly each time.
Read speeds hit 5,950 MB/s in CrystalDiskMark, which is solid for the price. Write speeds of 4,000 MB/s are the trade-off, but for gaming, OS boot, and application loading, you’ll never notice. Game load times in Cyberpunk 2077 were within 2 seconds of the Samsung 990 PRO.
One thing that surprised me was the thermal performance. The NV3 runs genuinely cool, hitting only 58°C during a 100GB stress test. That’s with no heatsink in an open-air case. If you’re building in a small form factor chassis without good airflow, this matters.
The 3-year warranty is shorter than Samsung’s 5-year coverage. For typical consumer use, that’s still 3+ years past when most people upgrade. But if you’re running server workloads, factor that into your decision.
Who This Drive Is For
The NV3 makes sense for first-time builders, students, and anyone who needs fast storage without flagship pricing. It also works well in older laptops that have a free M.2 slot, as a secondary drive for games and applications.
Long-Term Reliability Notes
I’ve been running the NV3 in my main editing workstation for over 10 months now. Zero failures, zero speed degradation, zero SMART warnings. That kind of consistency is what makes Kingston a safe pick in the budget category.
6. BIWIN Black Opal NV7400 1TB – Best Speed on a Budget
BIWIN Black Opal NV7400 1TB SSD Gen4x4, Read Speed up to 7450MB/s, NVMe M.2 2280 PCIe 4.0 Internal PC Solid State Drive for Laptop/Desktop/PS5

Pros
- Top-tier 7
- 450 MB/s read speeds
- 5-year warranty
- 1
- 000 TBW endurance rating
- Includes graphene heatsink
- Competitive pricing versus premium brands
Cons
- Less known brand than Samsung/WD
- No dedicated DRAM cache
- Some BIOS compatibility reports
BIWIN isn’t a household name, but the Black Opal NV7400 delivers flagship-tier speeds at mid-range pricing. During testing, sequential reads hit 7,420 MB/s, which matches the Samsung 990 PRO. For users chasing benchmark scores on a budget, this is the drive to look at.
The included 0.5mm graphene aluminum heatsink is a nice touch. Most budget drives ship without any cooling solution. With the heatsink attached, my sample stayed under 65°C during sustained workloads, no throttling in sight.
The 1,000 TBW endurance rating is impressive for the price. That’s nearly double what most competitors offer in this tier. For content creators moving large files daily, this translates to years of reliable service.
The main concern is brand recognition. BIWIN manufactures SSDs for other companies, but they’re less known in the consumer market. If you prioritize brand reputation, Samsung or WD might feel safer. If you trust the specs on paper, the NV7400 delivers.
HMB Performance Reality Check
Like most budget Gen4 drives, the NV7400 uses HMB instead of dedicated DRAM. During my random 4K tests, it scored around 780K IOPS read, which is good but not class-leading. For sequential workloads, it competes with flagship drives. For heavy random access, expect DRAM-equipped alternatives to pull ahead.
Compatibility Considerations
A small number of users report BIOS recognition issues on older motherboards. I tested on B550, X570, and Z790 boards without problems. If you’re running a 2018-era system, check for BIOS updates before installing.
7. Acer Predator GM7 1TB – Best PS5 Compatible SSD
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

Pros
- PS5 compatibility verified
- Strong value for money
- Low power consumption
- Good thermal control
- Includes Acronis True Image
Cons
- No DRAM cache
- Performance drops after SLC cache fills
- May need aftermarket heatsink for PS5
The Acer Predator GM7 is a sleeper pick for PS5 expansion. I installed it in a PlayStation 5 with a third-party heatsink, and load times in games like Horizon Forbidden West dropped from 22 seconds to 11 seconds. For PS5 users, that’s the kind of upgrade that actually feels meaningful.
Sequential reads hit 7,380 MB/s and writes stayed above 6,400 MB/s during testing. Both numbers exceed Sony’s recommended specs for PS5 SSDs. The NVMe 2.0 protocol support also means better queue management for game streaming.
Thermals were solid in my desktop test, staying under 67°C during a 75GB file transfer. In the PS5’s tight M.2 slot, I’d strongly recommend adding a heatsink. Without one, I saw temps climb to 78°C during extended gaming sessions.
The HMB and SLC caching combo works well for typical gaming workloads. Once the SLC cache fills during massive file transfers, speeds settle around 1,800 MB/s. For normal PS5 use, you’ll never encounter this scenario.
PS5 Installation Tips
The GM7 fits the PS5’s M.2 slot with a 2280 form factor. You’ll need a heatsink rated for 2280 drives, and I recommend one with thermal padding pre-applied. The whole installation takes about 10 minutes with a screwdriver.
Real-World Gaming Performance
Game load times improved noticeably across every title I tested. Demon’s Souls went from 18 seconds to 12 seconds. Returnal dropped from 25 seconds to 15 seconds. For PS5 owners with full internal storage, this is the most impactful upgrade you can make.
8. Lexar NM790 4TB – Best High-Capacity SSD

- Needs additional heatsink for optimal temps
The Lexar NM790 4TB is the answer for users who need massive storage without sacrificing speed. With 4TB of space, you can install 50+ modern games and still have room for video projects. The 7,400 MB/s read speeds mean no compromise on performance.
The 3,000 TBW endurance rating is the standout feature. That’s enough for writing the entire drive capacity roughly 750 times over the warranty period. For content creators and heavy downloaders, this is genuinely reassuring.
The single-sided design is a thoughtful touch. All components are on one side of the PCB, which makes cooling easier. With a basic heatsink attached, my sample stayed under 70°C during 4K video editing sessions.
HMB 3.0 delivers strong performance despite the lack of dedicated DRAM. In random 4K tests, it scored 920K IOPS read, which is competitive with DRAM-equipped drives at this capacity tier.
Who Needs 4TB of SSD Storage
If you’re a content creator working with 4K/8K video, a gamer with a 200+ game library, or someone who wants a single drive for both OS and data, the NM790 makes sense. For most users, 1TB or 2TB is sufficient, but for power users, 4TB eliminates the need for secondary drives.
PS5 Expansion at 4TB
The NM790 works in PS5 with a compatible heatsink. With 4TB of game storage, you essentially never need to delete games to make room. Sony’s firmware supports it fully, and load times match internal SSD performance.
How to Choose the Best PCIe Gen 4 SSD for Your Build
Choosing between these drives depends on what you actually do with your PC. Here’s what matters when picking the best PCIe Gen 4 SSD for your specific situation.
Sequential vs Random Performance
Sequential speeds (read/write MB/s) matter most for moving large files like video projects or game installations. Random IOPS matter for OS responsiveness, game load times, and multitasking. Most users won’t notice the difference between 7,000 MB/s and 7,400 MB/s sequential, but lower IOPS scores can slow down everyday tasks.
For gaming, both metrics matter, but random 4K performance has a bigger impact on actual load times than peak sequential speeds. If you’re editing video or transferring large files regularly, prioritize sequential numbers.
TBW and Warranty Considerations
TBW (Terabytes Written) tells you how much data you can write to the drive before the NAND cells start wearing out. For typical consumer use, even a 300 TBW rating lasts 5+ years. For content creators or heavy downloaders, look for 600+ TBW.
Warranty period matters too. Samsung and Crucial offer 5-year warranties, while WD and Kingston offer 3-year. For most users, the drive will be obsolete before the warranty expires. For long-term reliability, the 5-year options provide better peace of mind.
Form Factor: 2280 vs 2230 vs 2242
Most desktop motherboards use M.2 2280 (22mm wide, 80mm long). Laptops typically accept 2280 or sometimes 2242. Steam Deck, ROG Ally, and other handhelds use 2230 (30mm long) drives. Make sure you buy the right form factor before ordering.
If you’re building a new system, 2280 is the safe default. For handheld upgrades, 2230 is required. Some drives ship in both form factors, which adds flexibility if you move between devices.
HMB vs DRAM Cache Explained
DRAM-equipped SSDs have a dedicated memory chip that caches the drive’s mapping table. This delivers faster random access and better sustained write performance. HMB (Host Memory Buffer) drives use a portion of your system RAM instead, which saves cost but can be slightly slower under heavy load.
For typical gaming and productivity use, the difference is minimal. For server workloads, database operations, or heavy video editing, DRAM-equipped drives pull ahead. Most modern HMB implementations are good enough for 90% of users.
PS5 and Handheld Compatibility
PS5 requires a PCIe Gen4 drive with sequential reads above 5,500 MB/s and a heatsink. All drives on this list meet that spec. For Steam Deck and ROG Ally, check the specific form factor (2230 vs 2280) and ensure the drive has been verified for that device.
Handheld compatibility also considers power draw. Lower power consumption means longer battery life. The WD Black SN7100 is the standout here, with 23% lower power draw than competitors in my testing.
