AS-SSD Incompressible Sequential Performance

The AS-SSD sequential benchmark uses incompressible data for all of its transfers. The result is a pretty big reduction in sequential write speed on SandForce based controllers.

AS-SSD performance is pretty impressive as well. We see a huge advantage over a single Vertex 3.

    Would be nice to see one of these against a Fusion IO drive. Those are enterprise PCIe SSD's but I wonder how they'd compare.

    You should try to get one for Johan and test it under vSphere.

    a more direct comparison would be with the LSI Warpdrive. TBH, OCZ still isn't ready for prime time in the enterprise regardless of who's ASIC they're using. If they want to play with the big boys, they need a solid support staff and design team in place.

    one quick quirk with this card is the full height, half-depth design + daughterboard. in a card-dense chassis (esp. 1U systems), this won't fly. An LSI WarpDrive, for contrast, is half-height, half-depth @ 300GB.

    I don't know why you think enterprise means they need 'solid support'. This may be true for some organizations, but probably does not apply to the companies that would actually be interested in seeing these benchmarks. Reply

    I think as in support for (server) OS's other than Windows. These things could be nice for desktop virtualization. There you typically don't need lots of disk space but you need massive IO when people start working and stuff. Bootstorms kill VDI. Reply

    This card wouldn't do a bad job at bootstorms for VDI use cases but the WarpDrive's forte is going to show up there pretty strongly. ;) Reply

    OCZ is deciding to move upmarket and not just focus on consumers and SMB anymore. when that move occurs, they need to have an ecosystem that will support the inclusion of these devices in systems, not just try to price themselves into systems. OCZ also has a storied history of reliability issues that are going to impact this as well. Reply

    Storagereview.com has it compared to the LSI Warpdrive.

    interesting review with the knowledge that most of the workloads i've used the warpdrive for are shown to be it's forte...and it's still a generation behind in ASICs (SF-1200 vs SF-2xxx). I know there'll be a refresh of that part. ;) Reply

    Storage Review just did a side by side review of the Revo and Warp cards although they are intended for different markets. For a fraction of the price the OCZ Revo outclassed or matched the LSI Warp in most real world benchmarks. The only areas where the Warp led were due to it having HW RAID with six SF1200 processors tied to SLC memory along with a $8000-$10000 price tag.

    The results show that the design team at OCZ utlizing a custom virtual controller and async MLC memory created a product that offers a great deal of performance for a pretty good price.

    I was about to include that in my post but saw you beat me to it. Would definitely be interested in that as well. Reply
