In-Depth Reviews
1. Why 2TB Is the Gen5 Sweet Spot
Several Gen5 lines publish their highest speeds for 2TB and larger models. SanDisk lists its 14,900MB/s and 14,000MB/s figures for the 2TB and 4TB GX PRO 8100, for example. 2TB also costs far less than 4TB while leaving room for 15 to 20 large modern games.
If you only need a boot drive, a 1TB Gen5 drive is fine. For games and creative work, 2TB is the better long-term pick.
2. SanDisk Optimus GX PRO 8100 2TB: Best 2TB PCIe 5.0 SSD
The SanDisk Optimus GX PRO 8100 2TB reads at up to 14,900MB/s and writes at up to 14,000MB/s, with random speeds up to 2.3M and 2.4M IOPS. SanDisk claims over 2x higher power efficiency than its PCIe Gen4 drive and uses 8th generation BiCS TLC NAND with nCache 4.0.
3. Samsung 9100 PRO 2TB: Best Samsung 2TB Gen5
The Samsung 9100 PRO 2TB reads at up to 14,700MB/s and writes at up to 13,400MB/s, with random speeds up to 1,850K and 2,600K IOPS. Samsung's 5nm controller improves power efficiency by up to 49% over the 990 PRO, and the line goes up to 8TB.
4. Kingston FURY Renegade G5 2TB: Best 2TB Gen5 With DRAM
The Kingston FURY Renegade G5 2TB reads at up to 14,800MB/s and writes at up to 14,000MB/s. Kingston uses a 6nm SM2508 controller, low-power DDR4 cache, a Buck IC and a 12-layer PCB for cooling and stable power.
5. Lexar NM1090 PRO 2TB: Best Value 2TB Gen5
The Lexar NM1090 PRO 2TB reads at up to 14,000MB/s and writes at up to 13,000MB/s. It shares the 6nm controller and DRAM plus SLC caching of the 1TB model and supports DirectStorage.
6. Acer Predator GM9000 2TB: Best Acer 2TB Gen5
The Acer Predator GM9000 2TB reads at up to 14,000MB/s and writes at up to 13,000MB/s, which Acer describes as double PCIe 4.0 performance.
7. Sabrent Rocket 5 2TB: Best 2TB Gen5 for DirectStorage
The Sabrent Rocket 5 2TB reaches transfers of up to 14GB/s over PCIe 5.0, and Sabrent says its firmware is optimized for DirectStorage. You can use your own heatsink or buy Sabrent's dual heatpipe cooler separately.
How to Choose a 2TB PCIe 5.0 SSD
Confirm a Gen5 slot
Without one, a Gen5 drive runs at Gen4 speed.
Cache design
Kingston uses low-power DDR4 cache and Lexar uses DRAM plus SLC cache, which help with sustained work.
Plan cooling
Use your board's M.2 heatsink or see our Gen5 SSDs with heatsinks.
Seller
Samsung and SanDisk 2TB models were sold by Amazon when we checked.
Quick Setup Tips
- Check your slot: your motherboard manual lists which M.2 slot runs at full speed
- Fit a heatsink: use the board's M.2 cover or a drive with one fitted
- Clone or fresh install: free cloning tools move your old drive over
- Update firmware: use the maker's software after install
- Check the live price: use the buttons to see the current price on Amazon
