Corsair is using Silicon Motion's new SM2246EN SATA III 6Gbps controller along with 128Gbit Micron L85 20nm ONFI MLC NAND for the Corsair Force LX lineup. This combination gives the Corsair Force LX series a maximum sequential read speed of 560MB/s, which is as good as it gets for SSDs using the SATA III interface. When it comes to write speed the Corsair Force LX 128GB drive has a maximum sequential write speed of 150MB/s and the 256GB model is rated at up to 300MB/s. Read on to see how the Corsair Force LX 256GB drive does when we put it to the test!
