Everything that decides whether the Lexar NM790 is the right drive: controller, DRAM, NAND, rated endurance, PS5 and laptop fit, and how it compares with the obvious alternatives. Hardware facts are taken from the reviews and datasheets listed at the bottom; capacities and speeds come from our comparison of 60 drives.
Who it’s for: Value-focused builders and PS5 owners who want TLC NAND and Gen 4 speed, with higher rated endurance (TBW) than most rivals at each capacity. Skip it for: Buyers who want a DRAM cache for heavy mixed workloads; one reviewer saw performance drop once the drive was about 30% full.
| Controller | Maxiotech MAP1602 |
| DRAM cache | No — DRAM-less, uses 32–40 MB of host memory (HMB) |
| NAND | YMTC 232-layer TLC (per reviewers' testing) |
| Interface | PCIe 4.0 x4, NVMe, M.2 2280 |
| Heatsink version | A heatsink version exists at 1TB, 2TB and 4TB; reviewers recommended it because the bare drive ran warm under long benchmarks. |
| Capacity | Seq. read | Seq. write | Endurance | Warranty |
|---|---|---|---|---|
| 8 TB | 7,000 MB/s | 6,500 MB/s | — | 5 yr |
Rated endurance is 500 TBW at 500GB, 1,000 TBW at 1TB, 1,500 TBW at 2TB, 3,000 TBW at 4TB. We could not confirm the rating for the 8TB model from a primary source, so it is left blank. Speeds are the manufacturer’s sequential ratings.

We show retail prices only while we can refresh them at least every 24 hours. For market context: TrendForce’s 16 Oct 2026 retail sample runs $133–$250 per TB for mainstream 1–2TB drives, and NAND contract prices are forecast +15 to +20% for 4Q26. Check any listing against that range with the price per TB calculator, and see the SSD price chart for the trend.
