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.

It’s Indilinx’s first 6Gbps controller, good for up to 520MB/s reads and 410MB/s writes (but “only” 20K 4KB random write IOPS). The reference drive features two supercaps as its power loss protection circuitry. Everest will start at 64GB and be available in configurations of up to 1TB at customer request.

Given that OCZ owns Indilinx, I’m expecting some pretty aggressive pricing from these controllers. Still no word on a new consumer based Indilinx drive. OCZ did have a Vertex Plus on display, which is the old Barefoot controller but with new firmware that allegedly improves performance up to 500%. I have yet to test the aforementioned firmware so I’m not really sure how accurate the claims are.

It’s clear that Indilinx based drives aren’t going to be outperforming SandForce anytime soon, but the question is whether or not they’ll get good enough to be a value alternative.
