ADATA unveiled its newest performance-segment consumer SSD, the XPG SX910. The new product appears to be a slightly improved version of the XPG SX900 the company launched back in February, 2012.
According to the company, the NAND flash chips used in the XPG SX910 are put through an improved screening process, picking the best performing ones out for building these drives. In industry jargon, the process is known as binning. It's likely that this change enhanced the product warranty. The XPG SX910 comes with a longer product warranty of 5 years, compared to 3 years of the XPG SX900.
Despite improved NAND flash chips, the rated sequential transfer rates advertised for the XPG SX910 haven't changed from those of the XPG SX900. The drive reads at speeds of up to 550 MB/s, and writes at speeds of up to 530 MB/s. Its maximum 4K random read/write performance is rated at 50,000 and 85,000 IOPS, respectively. Perhaps the improved flash chips result in improved "performance yields" (the performance you actually end up with).
The ADATA XPG SX910 is driven by LSI-SandForce SF-2281 processor. It comes in three capacities, 128 GB, 256 GB, and 512 GB. Unlike with the XPG SX900 series, a 64 GB model is excluded. The drives also take advantage of a reworked over-provisioning scheme by LSI, which results in higher unformatted capacity. The drives are built in the 2.5-inch / 9.5 mm-thick form-factor, with SATA 6 Gb/s interface.
The 128 GB variant sells for US $189.99 (S $242), the 256 GB variant for US $379.99 (S $485), and the 512 GB for US $749.99 (S $957). The three will gradully phase out older XPG SX900 models from the market.
