The ADATA SE900G is a solid-state drive in the M.2 2280 form factor, launched on February 3rd, 2021. It is available in capacities ranging from 512 GB to 2 TB. This page reports specifications for the 1 TB variant. With the rest of the system, the ADATA SE900G interfaces using a PCI-Express 3.0 x4 connection. The SSD controller is the SM2262ENG from Silicon Motion, a DRAM cache chip is available. ADATA has installed 96-layer TLC NAND flash on the SE900G, the flash chips are made by SpecTek. To improve write speeds, a pseudo-SLC cache is used, so bursts of incoming writes are soaked up more quickly. The SE900G is rated for sequential read speeds of up to 2,000 MB/s and 2,000 MB/s write.
At its launch, the SSD was priced at 160 USD. The warranty length is set to five years, which is an excellent warranty period. The TBW rating for the ADATA SE900G 1 TB is unknown.
