Key strengths
Rated up to 7,250 MB/s sequential read and 6,450 MB/s sequential write, with up to 850K random read and 1.2 million random write IOPS at 2 TB.
Samsung lists AES 256-bit encryption with TCG Opal 2.0 and IEEE 1667, a 3 mW PS4 sleep state, and Samsung Magician support for data transfer, drive health and firmware updates.
Samsung claims up to 38% better sequential performance per watt than the 990 PRO in its own 2 TB test, and the drive is backward compatible with PCIe 3.0.
Before you buy
The limited warranty is 3 years or 800 TB written, whichever comes first.
Samsung specifies Host Memory Buffer caching and lists no onboard DRAM. Peak write figures use Intelligent TurboWrite, and no post-cache write speed is published.
Capacities stop at 2 TB, and Samsung does not state the NAND cell type.
