The 510 series will use the same 34nm NAND MLC flash chips as the second-gen X-25M and will debut in two capacities: 120GB and 250GB. Both will use the familiar 2.5-inch x 9mm form factor. According to VR-Zone, the 120GB model is supposedly priced at about $280 while the 250GB is $580, but at least one online retailer in the UK has listed them at £227 (~$366) and £475 (~$767).
With nearly double the read speed of Intel's second-gen X-25M, it goes without saying that the new drives are aimed at performance buffs. The 510 series touts peak read and write rates of 470MB/s and 315MB/s, though it's unclear if those speeds are limited to the largest capacity model. By comparison, the quickest X25-M G2 has read and write rates of 250MB/s and 100MB/s.
