CES: the Vertex 2 SandForce
Written by Damien Triolet

A whole range of Vertex 2 SSDs based on the very promising SandForce controller will soon be available from OCZ. The basic version, the Vertex 2, will be based on 34nm MLC memory and the SF-1200 version of the controller, limited to 9500 IOPS (4KB random) and will be available in 50, 100, 200 and 400 GBs. Up the range, the Vertex 2 Pro will be similar but equipped with the SF-1500 that can go up to 19000 IOPS at slightly higher speeds (280/270 MB/s reads/writes as against 270/260 MB/s). Lastly, the Vertex 2 Pro EX will use 50 nm SLC memory with the SF-1500. With identical speeds to the Vertex 2 Pro, they will be available at 50, 100 and 200 GB, the 400 GB version not possible here given the lower density of SLC memory.
