AMD today announced its Radeon R7 line of mainstream solid-state drives. Built by OCZ, the drives feature Toshiba-made MLC NAND flash, and OCZ's Indilinx Barefoot 3 M00 processors. Built in the 7 mm-thick 2.5-inch form-factor, the drives feature SATA 6 Gb/s interface, and are available in three capacities, 120 GB, 240 GB, and 480 GB. All three offer sequential read speeds of up to 550 MB/s; while the 120 GB variant offers up to 470 MB/s of sequential writes; the 240 GB and 480 GB ones offer up to 530 MB/s. Their 4K random read performance numbers are up to 85,000 IOPS, up to 95,000 IOPS, and up to 100,000 IOPS, respectively; while the 4K sequential write performance for all three are rated at up to 90,000 IOPS. The Radeon R7 is essentially an OCZ Vector 150 with lighter processor clocks, and could be priced accordingly.
