Should you have purchased a SandForce 22xx-based SSD from ADATA, they have new firmwares available. Genric rule of thumb here though is, don't update if it aint broke okay ? The models include all volume models of the SX910, SX900, SP900, SP800, S511, S510 and S396. Version 5.0.7a improves TRIM performance, which affects the drives' write speeds. The firmware is also said to fix other "minor issues," although the company didn't detail them. The firmware is available as both the EEPROM binary image, and as an updater for popular operating systems. Grab it here.
