SSD + HDD + PCIe = OCZ RevoDrive Hybrid
OCZ has announced the RevoDrive Hybrid, which pairs a 2.5" hard drive and a cache SSD onto a single PCIe add-on card. Read on for more details and some performance numbers.
OCZ is going all in for their SSD business. Apart from their power supplies, they've pretty much dropped everything else. Nearly their entire Computex booth is dedicated to SSDs, where a few years ago you would have seen mostly memory and power supplies.
Today, OCZ announced the RevoDrive Hybrid. As its name implies, the SSD now acts as a cache for an onboard 2.5" hard drive. The SSD part of the RevoDrive Hybrid uses four SandForce SF-2200 controllers in RAID 0, which should make for some blazing fast performance.
The card will come bundled with the 2.5" drive – It's not clear whether it will be possible to swap the drive out for another. The RevoDrive will be available in capacities ranging from 240GB to 960GB, though the SSD cache size was not stated. Like previous RevoDrives, this one also works off PCI Express x4.
Quoted speeds are 575MB/s read and 500MB/s write. OCZ had a live demo running ATTO, which yielded 740+MB/s read and 540MB+MB/s write. Of course, ATTO represents a best-case scenario, especially for SandForce controllers which use on-the-fly compression.
The RevoDrive Hybrid is expected to be released in July. This will be a very interesting alternative to Z68 and Marvell/Highpoint controllers.
