Description
The 990 PRO is Samsung's top consumer NVMe line and the 4 TB variant is the one specified when a single drive has to hold an entire project library. It pairs the in-house Pascal controller with V-NAND TLC and a 4 GB LPDDR4 buffer, which is what keeps random performance flat as the drive fills.
Key specifications
- Sequential 7450 MB/s read, 6900 MB/s write — at the practical ceiling of PCIe 4.0 x4
- Random 1600K / 1550K IOPS (4K, QD32)
- 2400 TBW endurance, 5-year limited warranty
- Samsung V-NAND TLC with 4 GB LPDDR4 DRAM cache
Where it fits
Video editing and 3D workstations, large local datasets, and PC builds where the motherboard offers only one or two M.2 sockets and each one has to count. Supplied without a heatsink — pair it with the board-side M.2 heatspreader.
Trade notes
Retail-boxed. Warranty handled through Samsung's regional service network on presentation of the serial. Bulk tray packaging can be quoted on volumes above 50 units.
