Everything that decides whether the Lexar NQ780 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: Large, low-cost storage at 4TB with unusually high rated endurance for QLC (2,400 TBW). Skip it for: Long writes: PCWorld measured about 450 MB/s once the SLC cache is full, and the 1TB model is noticeably slower than the 4TB.
| Controller | Innogrit IG5236 |
| DRAM cache | No — DRAM-less, uses 64 MB of host memory (HMB) |
| NAND | 144-layer QLC (Intel/Solidigm-made, Longsys-branded) |
| Interface | PCIe 4.0 x4, NVMe, M.2 2280 |
| Heatsink version | Not in our data — sold bare |
| Capacity | Seq. read | Seq. write | Endurance | Warranty |

Rated endurance is 600 TBW at 1TB, 1,200 TBW at 2TB, 2,400 TBW at 4TB. Speeds are the manufacturer’s sequential ratings.
Every Lexar NQ780 capacity in our comparison, smallest first.
Full list of qualifying drives: PS5-compatible SSDs.
Crucial P310: another DRAM-less QLC Gen 4 drive.
Lexar NM790: Lexar's TLC drive, with better sustained writes.
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.

Where reviews disagreed (for example on NAND layer counts or a capacity’s endurance rating) we state only what the sources agree on.
