If you want the best NVMe SSDs for fast boot times, the most useful thing to know first is that the drive is only part of the story. A controlled Windows 10 comparison published by ITIGIC found a full boot just over 3 seconds faster on NVMe than on a SATA SSD (about 23.9 seconds versus 27.2 seconds), because firmware startup, Windows services and startup programs make up most of the wait. So a faster drive helps, but a PCIe 5.0 model will not turn a 20-second boot into a 5-second one. Where a good NVMe drive does pay off is in game loading, large file copies and general responsiveness.
A note on method. These picks come from published specs, manufacturer documentation and reviewer feedback. We did not test any of these drives ourselves. Prices change often and were not checked live, so treat any figure as approximate and confirm it on the product page.
How to Choose an NVMe SSD for Quick Boots
- Match the interface to your board. PCIe 4.0 drives such as the Samsung 990 Pro, WD_BLACK SN850X and Crucial T500 already sit close to the Gen4 speed ceiling. PCIe 5.0 drives need a motherboard slot that supports Gen5 to reach their rated speeds; in a Gen4 slot they are limited by the slot.
- Do not chase sequential speed for boot alone. Boot and app launches lean on small random reads and on how the whole system starts, not on headline MB/s. Reviewers also point out that Gen4 drives are already very fast for everyday use.
- Plan for heat. Gen5 drives run hotter. Windows Central recorded controller temperatures reaching 99 C on the WD_BLACK SN8100 in repeated stress tests and called a heatsink effectively mandatory. Use the motherboard heatsink or a model with one included.
- Prefer drives with a DRAM cache and TLC flash for steadier sustained performance. We confirmed TLC with DRAM only for the SN850X and T500 in our sources; check the spec sheet of any other drive.
- Check the slot. Make sure your motherboard or laptop has a free M.2 2280 slot and enough clearance for a heatsink version.
Best NVMe SSDs for Fast Boot Times: 5 Picks
1. Samsung 990 Pro (PCIe 4.0)
Samsung lists the 990 Pro in 1 TB, 2 TB and 4 TB capacities, as a PCIe 4.0 NVMe M.2 drive rated up to 7,450 MB/s read and 6,900 MB/s write. A version with a heatsink is also sold. Several 2026 roundups name it the best all-around Gen4 choice.
Pros: very high Gen4 speeds, mature software (Samsung Magician), heatsink option for consoles or cramped boards. Cons: usually priced above value Gen4 drives, and Gen5 models are faster on paper. Best for: most desktop and laptop upgrades where you want a dependable fast boot drive.
2. WD_BLACK SN850X (PCIe 4.0)
The SN850X is an M.2 2280 PCIe 4.0 x4 drive rated up to 7,300 MB/s read. Write ratings are reported as 6,300 MB/s on the 1 TB and 6,600 MB/s on the 2 TB and 4 TB, though sources differ slightly, so confirm against the official datasheet. It uses TLC flash with DRAM and is sold with or without a heatsink.
Pros: TLC flash with sustained-write behaviour reviewers like, bare and heatsink versions. Cons: slightly behind the 990 Pro on paper, can run warm without a heatsink in low-airflow cases, and the heatsink version does not fit under every motherboard cover. Best for: PS5 owners and builders who want a strong Gen4 drive with a choice of cooling.
3. Crucial T500 (PCIe 4.0)
The 2 TB T500 is rated at 7,400 MB/s read and 7,000 MB/s write, with a Phison E25 controller, Micron 232-layer TLC flash, a discrete DRAM cache and 1,200 TBW endurance. PCGamesN measured 7,456 MB/s read and 7,034 MB/s write in CrystalDiskMark, matching the claims.
Pros: near the Gen4 ceiling, DRAM cache, strong real-world transfer results in several reviews. Cons: PCGamesN found it often beaten in 4K random tests by rivals such as the Solidigm P44 Pro, and StorageReview’s verdict was more mixed than other outlets. Best for: buyers who want Gen4 speed and will compare street prices between the T500, 990 Pro and SN850X.
4. WD_BLACK SN8100 (PCIe 5.0)
The SN8100 is rated up to 14,900 MB/s sequential read. Trusted Reviews measured 14,832 MB/s read and about 14,012 MB/s write; PC Gamer measured 14,710 MB/s read and 13,926 MB/s write. Club386 lists capacities up to 8 TB and a five-year warranty, and a heatsink version exists. Tom’s Hardware called it one of the most efficient drives it has tested.
Pros: among the fastest consumer drives in the reviews, efficient for a Gen5 model. Cons: runs hot (see the 99 C reading above), costs a lot (the 2 TB was around $280 in one review), and the jump over Gen4 is hard to feel in everyday use. Best for: Gen5-capable builds that also move very large files and have good airflow.
5. Samsung 9100 Pro (PCIe 5.0)
Samsung rates the 9100 Pro at 14,700 MB/s read on the 1 TB and 2 TB models and 14,800 MB/s on the 4 TB and 8 TB, with writes of 13,300 MB/s on the 1 TB and 13,400 MB/s on larger sizes. Versions with and without a heatsink are sold. StorageReview measured peak speeds of 14,800 MB/s read and 13,400 MB/s write.
Pros: capacities up to 8 TB, lean power draw, and some reviewers (Dong Knows, Club386) describe it as cool for a Gen5 drive. Cons: reviews conflict on heat (NAS Compares reported up to 81 C under sustained load and recommends active cooling or the heatsink model), the heatsink version adds roughly $40, and real-world gains over Gen4 are small. Best for: Samsung fans building on a Gen5 platform who want a heatsink option from the same brand.
Other Things That Speed Up Boot
- Trim startup apps. Disable programs you do not need at login in Task Manager.
- Keep Fast Startup enabled if you shut down rather than restart; it cut boot times sharply in at least one forum-reported comparison.
- Update your BIOS only following your motherboard maker’s instructions, since older firmware can add to startup time.
FAQ
Will an NVMe SSD make my PC boot much faster than a SATA SSD?
Usually only a few seconds. The ITIGIC test we found showed about a 3-second gain, and firmware plus Windows startup tasks make up much of the total. The gap is larger when upgrading from a hard drive.
Is PCIe 5.0 worth it for boot times?
For boot alone, reviewers suggest not. Gen4 drives are already very fast, and Gen5 adds heat and cost. It makes more sense for heavy file work on a Gen5-capable board.
Do I need a heatsink?
For Gen5 drives, yes in practice: use the board heatsink or buy a heatsink model. For Gen4 drives, it depends on airflow, and a heatsink is recommended in a PS5 or a hot case.
Which capacity should I buy?
Many reviewers point to 2 TB as the sweet spot on price per terabyte, but our sources did not agree on a single rule, so compare current prices for your needs.
