A-Data's long stoped S501 SATA 6Gb/sec SSDs have finally broken cover getting impressive read speeds to the 2.5in form components thanks to a Marvell controller and speedy multi-level cell NAND flash.

Present in 64GB, 128GB, 256GB, and 512GB,add 128MB of DDR3 cache and are beautifully aimed at the greater end of the market in case the inclusion of a speedy SATA 6Gb/sec interface wasn't sufficient of a idea in that regard.

As you would want A-Data has tried to take full interest of the rise in data transfer capabilities given by the SATA 6Gb/sec interface pushing the Toshiba MLC NAND chips to their limit through the Marvell-based controller and offering speeds of 480MB/sec read and 310MB/sec write although the firm warns that these figures will suffer if the drive is joins to a SATA 3Gb/sec controller.

While the speeds quoted by A-Data don't come anywhere close the impressive capabilities of PCI Express-based SSDs such as the OCZ RevoDrive X2 which can move 740MB/s, they're impressive nonetheless and come from a general 2.5in form component which add full support for working enhancement TRIM technology.
