Fusion-io has launched the ioDrive Duo, a new version of its PCI Express SSD that more than doubles performance in some cases up to 1.5 GB /s for read speeds and 1.4 GB /s for writes for the 320 GB version.

To get these performances, the ioDrive Duo combines two ioDrives through RAID, and it should be noted that it is possible to get them to function in mirroring rather than stripping, with performances that will of course be halved. For now the ioDrive Duo is available in 160, 320 and 640 GB versions and a 1.28 TB version is planned for the second half of the year. Heaven knows how much it’ll cost!
