The days of the high-performance SATA SSD may be dimming, thanks to NVMe M.2 drives' ever-smaller physical sizes and prices and their higher overall performance. In a couple of years, most new enthusiast systems will probably boot from NVMe drives, relegating SATA ports to handling hard drives for bulk storage. Adata thinks there's still life left in high-performance SATA drives, though, and its XPG SX950 SATA SSDs are designed to deliver high performance storage over the SATA 6Gbps bus. The SX950 is the company's first 2.5" SATA SSD to use 3D MLC flash memory, which the company says allows for higher density, increased performance, and higher durability over its other offerings. The drives are available in the usual 240GB, 480GB, and 960GB capacities.
Adata claims that all models can achieve peak read speeds up to 560MB/s and peak write speeds close to 530MB/s, depending on the drive capacity. The drives can do up to 90K random read IOPS and should hit up to 90K IOPS when writing. The controller is manufactured by SMI, though Adata doesn't specify the exact chip used. Those high performance figures are likely a result of the drives' SLC cache and DRAM buffer.
The company touts an endurance rating of "up to 800 TB," which we assume is the figure for the 960GB model. All models are rated for two million hours between failure, and are backed up with a six-year warranty.
Adata says the XPG 950 SSDs will be sold at TR favorites Newegg and Amazon, though the e-tailers don't appear to have the drives listed just yet. The 240GB model will be priced at $140, the 480GB version will go for $250, and the 960GB model should set you back $450.
