In terms of specifications, this solid-state drive adheres to the PCIe 4.0 x4 or 5.0 x2 standard, adopting the M.2 2280 form factor and utilizing V-NAND TLC flash memory. It boasts sequential read and write speeds of 5000/4200 MB/s and random read and write speeds of 700k/800k IOPS. Additionally, it features AES 256-bit encryption for data security. While the Pro model incorporates a DDR4 RAM cache, the Evo model does not seem to include one. This distinction is in line with the differing roles of the two SSDs, with the Pro version utilizing more robust V-NAND 3bit MLC flash memory. The M.2 SSD should achieve up to 5,000 MB/s via either PCIe 5.0 x2 or PCIe 4.0 x4.

The Samsung 990 EVO is equipped with a self-developed main control chip, the S4LY022, boasting a mean time between failures (MTBF) of 1,500,000 hours. It also supports Samsung's Magician SSD management software. As of now, specific launch dates and pricing details for the Samsung 990 EVO SSD remain unclear, but it is expected to become available soon.
