OCZ shows off PCI-E RevoDrive SSD

While most new SSDs come in a 2.50-inch laptop-friendly block, OCZ has just demonstrated what can be achieved if you spread out an SSD's components over a PCI-E card.

The company's new RevoDrive features not one, but two of Sandforce's acclaimed SF-1200 controllers on a PCI-E card. Having connected these together via RAID, OCZ claims that the card gets close to doubling the performance over standard drives with just one controller.

According to PC Perspective (opens in new tab), OCZ is making some impressive claims regarding data transfer rates. The company reckons that it's capable of a sequential read speed of up to 540MB/sec and a sequential write speed of up to 490MB/sec.

As a point of comparison, a standard single-controller SandForce drive, such as Corsair's Force range (opens in new tab), reads at up to 285MB/sec and writes at up to 275MB/sec. Of course, you'd achieve roughly the same effect by linking together a pair of 2.5-inch drives that both used the same Sandforce SF-1200 controller, but this option is potentially cheaper for desktop owners.

Tech Connect (opens in new tab) reports that the drive will be available in 120GB and 240GB capacities, costing €433 (£361) and €757 (£631) respectively. Given that a single 120GB OCZ Sandforce drive currently costs £310 inc VAT (opens in new tab), you could be looking at just an extra fifty quid to double your drive's performance.

OCZ has previously dabbled with PCI-E SSDs, with its Z-Drives commanding astounding data rates and capacities at equally ball-breaking prices (opens in new tab) (£6,580 for a 2TB drive). Although the RevoDrive won't be able to match these speed demons, it will certainly be much cheaper, and also more than fast enough for your average desktop owner.

Interestingly, the photo also shows a connector behind the two controller chips in the middle, plus several mounting holes, which suggests that a further expansion daughterboard may be available at a later date.

The RevoDrive requires a four-lane PCI-E slot (or a standard 16-lane graphics slot), and is expected to start shipping at the end of this month.
