The 2.5-inch drives use SandForce SF 2281 (120 GB, 240 GB) and SF 2282 (480 GB) controllers and Intel-manufactured MLC flash memory chips. According to the manufacturer, all drives are rated at 60,000 IOPS and deliver a maximum read performance of 550 MB/s and a write performance of up to 520 MB/s via a 6G SATA III interface.
The drive is targeted at the professional segment, but is marketed toward enthusiast users as well. We have seen the 120 GB version for a street price of about $220 and the 240 GB model for $385. The 480 GB model is not yet available.
