OCZ delivers some astonishing performance numbers with its latest generation 2.5: SSD

It seem as though each day is better than the next when it comes to new product announcements here at CES -- especially when it comes to the hot field of SSDs. Everyone is in a game of one-upmanship, with Micron announcing its 415/260 (read/write) RealSSD C400 on Tuesday and Corsair announcing its 480/320 Performance 3 Series yesterday.

Now it's OCZ's turn to blow everyone out the water with its new Vertex 3 Pro. The Vertex 3 Pro is based on SandForce's SF-2582 SATA III/6Gbps compliant controller, and delivers read speeds of a whopping 550MB/sec and write speeds of an almost equally blazing 525MB/sec.

When paired with a SATA III controller, the real world numbers are equally impressive. Anand Shimpi of AnandTech was able to record a maximum of 492MB/sec sequential read and 518MB/sec sequential write using a prototype drive.

"Performance may even increase by the time OCZ actually ships the drive," said Shimpi. "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 Vertex 3 Pro SSDs will be available in capacities ranging from 64GB to 512GB. We'll get your some up close and personal pictures of the SSDs (and hopefully a word on pricing) later today.

RE: Incompressable data - 260MB/s

You can store compressed data on an SSD, it's just the SandForce controller gets a lot of its relative speed from compressing and abridging data when it does writes. That is, the controller has to write less for a compressible chunk of data, so it appears faster. For data that's already compressed, the controller can't compress it further, so writes are now at their real speed.

No other SSD controllers do this, so what speed they have is the same over compressed and non compressed data, regardless.

It begs the question though. If you were to turn on, say Windows' filesystem compression, how would it compare to other SSDs?

If the speed is similar, in all honesty I think I would rather than the OS handle compression. That way I can turn it on/off on a directory-by-directory or even file-by-file basis. And I always know exactly how much real space each file takes on the drive, in case I ever need to clear up space.
