Saturating the Bandwidth
Jan 06, 2011
Today at CES, OCZ previewed its first SF-2000 based drives: the Vertex 3 Pro and Vertex 3 EX. Both are based on SandForce’s SF-2582 controller, the highest end offering in the SF-2000 family. The drives won’t see the light of day for months (sometime in Q2) and what OCZ is showing today is very, *very* early silicon and hardware. The drives are using 32nm Toshiba toggle-mode NAND (effectively DDR NAND), however OCZ will go to market with 25nm Intel NAND when the drive is ready.
The early, impressive benchmark:
When running highly compressible data (pseudo random in Iometer) at low queue depths, I get 518MB/s sequential write speed and nearly 500MB/s for sequential read speed. Remember this is the very first version of the drive and there’s months of tweaking ahead to get it ready for production. Performance may even increase by the time OCZ actually ships the drive. Furthermore, this is the performance of a single drive with a single controller - there’s no funny on-board RAID going on, we’re just talking about the performance of a single drive.
The vast majority of computers have SATA 3.0 connectors which means they're limited to a maximum of 300MB/s transfer rates. That's okay for hard drives which rarely push 150MB/s but not with lightning fast solid state disks which will debut later in 2011.
