There's a new PCIe SSD in town: the RevoDrive 3. Armed with two SF-2281 controllers and anywhere from 128 - 256GB of NAND (120/240GB capacities), the RevoDrive 3 is similar to its predecessors in that the two controllers are RAIDed on card. Here's where things start to change though.

In the past OCZ used a PCI-X RAID controller to keep costs down, but that's now gone. OCZ won't disclose the name of the controller vendor but a quick look at the card shows that it's native PCIe. The RevoDrive 3 itself is a PCIe 2.0 x4 card, however OCZ wouldn't confirm whether or not the controller was running at 2.0 or 1.0 speeds - just that the interface wasn't a bottleneck.

 
The other big improvement is that OCZ made some modifications to both the SandForce and on-board RAID controller firmware to allow everything from SMART data to TRIM to be passed through to the system host. In the past RevoDrive users were stuck with a PCIe card that couldn't be TRIMed, but with the 3 you get full TRIM support. Formatting the drive under Windows 7 or deleting files off of will result in those LBAs being TRIMed by the SF controllers. 
 
OCZ is promising up to 900MB/s reads and 700MB/s writes (highly compressible of course). Random writes are spec'd at up to 120,000 for 4KB transfers. OCZ expects the 240GB capacity to sell for $599.
 
In addition to the standard RevoDrive there's an X2 version with twice the controllers:

 
With four controllers the RevoDrive 3 X2 is good for up to 1.5GB/s reads and 1.2GB/s writes. OCZ is quoting up to 200,000 4KB random write IOPS. Again all of these figures are using highly compressible data. Just like the base RevoDrive 3, TRIM/SMART reporting are now supported on the x2.
 
Capacities start at 240GB ($699) and go all the way up to 960GB.

    599$ for 240GB isn't that bad. Any idea on the price of 120GB version? Reply

    If it follows suit with what they usually do, probably a bit more than half. $349-379? Reply

    Don't be silly, the 120gb will cost $299.5 Reply

    I've been waiting for this for a long time. Right product, right price.

    Bootable PCIe drive with RAID support and the current generation of SandForce controller.

    Hope it's compatible with my Gigabyte GA-X58A-UD7 motherboard!

    If so, it should be a great improvement over my Intel x25m G2 160GB SSD, currently the limiting factor in my computer's performance.

    What's the deal with linux on these things? It SHOULD just show up as any other HDD/SSD, but does it? I thought that some of the first ones confused Linux too much to boot from it. Reply

    I don't think so. The standard HDD/SSD shows up under Linux since they're powered by the SATA interface, not a PCIe interface. The nature of the driver structure under Linux kind of makes that somewhat impossible.

    Unless the drive shows up as a "PCIe controller that has a SATA controller built in" type of an arrangement, and does the appropriate translations in hardware.

    I'm definitely getting the 240GB x2 version.

    Gonna combine this with an OCZ vertex 3 with whatever capacity I can afford and possibly another high capacity HD as part of my new uber build!

    This is seriously overdue... how did OCZ of all people manage to pass TRIM commands through a RAID controller?! Reply
  • GullLars - Tuesday, May 31, 2011 - link

    Custom firmware. Considering it's RAID-0 and likely a HBA, it's probably a bit easier than more complex RAID sollutions. Reply
