The IRDM M.2 SSD is a solid-state drive in the M.2 2280 form factor, launched in 2021. It is available in capacities ranging from 512 GB to 1 TB. This page reports specifications for the 1 TB variant. With the rest of the system, the IRDM M.2 SSD interfaces using a PCI-Express 3.0 x4 connection. The SSD controller is the PS5012-E12S-32 from Phison. IRDM has installed 64-layer TLC NAND flash on the M.2 SSD, the flash chips are made by YMTC. Please note that this SSD is sold in multiple variants with different NAND flash or controller, which could affect performance, the "Notes" section at the end of this page has more info. To improve write speeds, a pseudo-SLC cache is used, so bursts of incoming writes are handled more quickly. The cache is sized at 30 GB, once it is full, writes complete at 800 MB/s. Copying data out of the SLC cache (folding) completes at 400 MB/s. The M.2 SSD is rated for sequential read speeds of up to 3,200 MB/s and 3,000 MB/s write; random IO reaches 250K IOPS for read and 500K for writes.
The SSD's price at launch is unknown. The warranty length is set to five years, which is an excellent warranty period. IRDM guarantees an endurance rating of 600 TBW, a typical value for consumer SSDs.
