OCZ Launches New RevoDrive 3 (X2)

by: admin Friday, July 15th, 2011

OCZ has launched its latest PCIe solid state drives for the enthusiast consumer market, the RevoDrive 3 and RevoDrive 3 X2, along with promises of exceptional performance. The new lineup is based on the latest SandForce controllers (SandForce-2281)–two or four of them working in an internal RAID 0 configuration to boost performance. TRIM support is also present and the speeds offered are up to 1.5GB/s and 230,000 IOPS.

OCZ is focusing on the most demanding consumers with the RevoDrive series–the main difference between the two new models is that the RevoDrive 3 uses two controllers, which the X2 version comes with four SF-2281 controllers to achieve even higher performance. The capacities range from 240 GB to 960 GB.

The big news with RevoDrive 3 is called VCA, Virtualized Controller Architecture, which uses a proprietary SAS RAID circuit that divides the data and sends different parallel I/O to the various controllers. This makes it possible to get the same performance as with RAID, while maintaining support for TRIM.

The problem remains that TRIM in Windows 7 has a well-known limitation that prevents it from issuing the TRIM command over any SCSI/SAS controller and this is a problem only Microsoft itself can solve. A solution is expected in the next generation Windows Server, but when the TRIM command will operate on the RevoDrive 3 together with Windows 7 is still unclear.

It is said to work with most Linux distros, as long as it is capable of sending out the TRIM command to a SCSI / SAS controller. None of the units are available on the market at this writing, but the price for RevoDrive 3 X2 will be $ 699.99 (240 GB), $ 1699.99 (480 GB) and $ 3199.99 (960 GB).

[Update: Thanks Albatorsk in the comments for pointing out the apparent fact that Linux drivers are missing and the link that confirms it:]

You should make some review of RAM SSD, such as HyperDrive5. They are the only mass-produced products with actual high IOPS regardless of the patterns and usage time.
I personally consider using some of them as a fast storage for some of my server databases, due to its reliability, actual speed and endurance. Their only problems (in the terms of reliability and performance) for now is low-speed controller and interface.

Good idea. The HyperDrive would definitely be interesting to take for a spin. It’s too bad about the SATA II interface, it looks like a RAID card and a dual drive setup is practically a must.

For RAM SSD any hardware RAID will do, including built-in, because the cache doesn’t provide any considerable benefit over the already fast RAM.

You should leave out the last part about Linux since it’s not true. The RevoDrive 3 does not work at all under linux, as there are not drivers available. They (OCZ) are not planning to make any either.

Does it mean that the device is incompatible with any common storage driver for Linux ?
Well, I’m not planning to use it (RevoDrive) for my servers anyway. For me it is either dedicated system with loads of RAM or RAM SSD or SAS or SATA NAND SSD, but not PCIe SSD cards.

Unfortunately that’s correct. None of the SCSI/SAS drivers in the linux kernel works with the RevoDrive 3.

A new product possible with “enterprise MLC NAND” from Micron with 30000 erase cycles – as implied by its warranty terms (about 18k erase cycles). Though should SLC be reasonably cheaper (it is unreasonably 2.5x overpriced), it would be more reasonable to use SLC there. At least the product seems to be much more usable compared with “normal” (low erase endurance) MLC.
I wonder when those PR and marketing games would finally settle down around SLC and MLC NAND.

Thanks Albatorsk for the Linux info! I’ve updated the post to reflect this.
