ADATA XPG SX8000 512GB MLC NVMe SSD (2026)
The ADATA XPG SX8000 512GB is a legacy enthusiast NVMe SSD with true MLC NAND and 256 MB DRAM, rated for 2,500/1,100 MB/s on PCIe 3.0.
Controller & Memory
The 512 GB SX8000 uses the Silicon Motion SM2260G controller with ADATA MLC NAND and 256 MB of Nanya DDR3 DRAM. It's a PCIe 3.0 x4 NVMe 1.2 drive in the M.2 2280 form factor.
ADATA rates the 512 GB model at 2,500 MB/s sequential reads and 1,100 MB/s sequential writes, with 160,000 random read IOPS and 140,000 random write IOPS. The 1,100 MB/s write speed is the main limitation — by modern NVMe standards, this is quite slow. The MLC NAND provides consistent write performance without relying on SLC caching, but the overall throughput ceiling is low.
The SX8000 line is available in 128GB, 256GB, 512GB, and 1TB capacities. The 512GB model is the most practical for modern use, though the performance is identical across all capacities.
ADATA backs the SX8000 with a five-year warranty. The drive is rated for 2 million hours MTBF.
The SX8000's main competitor is the ADATA XPG SX8200 Pro 512GB, which offers 3,500/3,000 MB/s for a similar or lower price. Other rivals include the Samsung 960 EVO 500GB and WD Black SN750 512GB. All of these outperform the SX8000 in sequential write speed.
The SX8000 is a legacy product. It was a good value when it launched in 2017, but modern NVMe drives offer substantially better performance at similar prices.
