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 512 GB 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 handled 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 100 USD. The warranty length is set to five years, which is an excellent warranty period. The TBW rating for the ADATA SE900G 512 GB is unknown.
