The Samsung 990 Pro is a solid-state drive in the M.2 2280 form factor, launched on August 24th, 2022. It is available in capacities ranging from 1 TB to 2 TB. This page reports specifications for the 2 TB variant. With the rest of the system, the Samsung 990 Pro interfaces using a PCI-Express 4.0 x4 connection. The SSD controller is the Pascal (S4LV008) from Samsung, a DRAM cache chip is available. Samsung has installed 176-layer TLC NAND flash on the 990 Pro, the flash chips are made by Samsung. To improve write speeds, a pseudo-SLC cache is used, so bursts of incoming writes are handled more quickly. The cache is sized at 226 GB, once it is full, writes complete at 1400 MB/s. Thanks to support for the fast PCI-Express 4.0 interface, performance is excellent. The 990 Pro is rated for sequential read speeds of up to 7,450 MB/s and 6,900 MB/s write; random IO reaches 1400K IOPS for read and 1550K for writes.
At its launch, the SSD was priced at 309 USD. The warranty length is set to five years, which is an excellent warranty period. Samsung guarantees an endurance rating of 1200 TBW, a typical value for consumer SSDs.
