ADATA Legend 800 500GB M.2 NVME Gen4 Solid State Drive ( SSD )

The ADATA Legend 800 500GB is a PCIe Gen4 x4 NVMe solid state drive built on the M.2 2280 form factor, making it compatible with both desktop and laptop systems that support the NVMe 1.4 standard. It delivers sequential read speeds of up to 3,500 MB/s and sequential write speeds of up to 2,200 MB/s, providing a substantial performance uplift over PCIe Gen3 and SATA-based storage solutions. Built with 3D NAND flash memory, the Legend 800 balances performance with endurance. The drive is rated for 300TB of total bytes written (TBW) and carries an MTBF of 1,500,000 hours, reflecting a strong reliability specification for everyday and creative workloads. SLC caching and Host Memory Buffer (HMB) support work together to maintain consistent throughput during sustained operations without requiring a dedicated DRAM chip. Data integrity is maintained through hardware LDPC (Low Density Parity Check) ECC technology, which detects and corrects bit errors during read and write operations. The drive's compact heatsink design — measuring 80 x 22 x 2.65 mm with the heatsink attached — assists with thermal management under sustained load, keeping temperatures within the rated 0°C to 70°C operating range. The Legend 800 is backward compatible with PCIe Gen3 slots, providing flexibility across a range of Intel and AMD platform generations. Shock resistance is rated at 1500G over 0.5 ms, and storage temperature tolerance spans -40°C to 85°C. The drive ships with ADATA's free SSD Toolbox software, enabling S.M.A.R.T. health monitoring, temperature tracking, capacity reporting, and firmware updates.
