The ADATA Legend 970 is a solid-state drive in the M.2 2280 form factor, launched in July 2023. 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 ADATA Legend 970 interfaces using a PCI-Express 5.0 x4 connection. The SSD controller is the PS5026-E26 from Phison, a DRAM cache chip is available. ADATA has installed 232-layer TLC NAND flash on the Legend 970, the flash chips are made by Micron. To improve write speeds, a pseudo-SLC cache is used, so bursts of incoming writes are soaked up more quickly. The cache is sized at 200 GB, once it is full, writes complete at 3400 MB/s. Copying data out of the SLC cache (folding) completes at 1350 MB/s. Thanks to support for the fast PCI-Express 5.0 interface, performance is excellent. The Legend 970 is rated for sequential read speeds of up to 10,000 MB/s and 10,000 MB/s write; random IOPS reach up to 1400K for reads and 1400K for writes.
At its launch, the SSD was priced at 330 USD. The warranty length is set to five years, which is an excellent warranty period. ADATA guarantees an endurance rating of 1400 TBW, a typical value for consumer SSDs.
