OCZ is continuously raising the bar for today’s Solid State Drive technology and after launching the first SSDs with an integrated RAID controller the time has come for the next big step; an external storage system connected via the PCI-E interface. OCZ has dubbed the product Z-Drive and is simply a SATA-RAID card paired with no less than four SSDs configured to run in RAID 0.
Judging from the specifications the drives are four OCZ Vertex harddrives each sporting 250GB storage capacity, which adds up to 1TB all in all, plus a local cache at 256MB (4x64MB).
Together with a hardware-based RAID controller this “little” things can achieve some impressive numbers, or what do you say about read speeds up to 700MB/s and write speed close to 500MB/s.
This is far higher than any SATA SSD can do in theory, not the least because of the limitations of the SATA interface, but at the same time it is less than what we originally expected from four OCZ Vertex harddrives in RAID 0. In theory the drives should peak close to 1000MB/s since Vertex has a specified read speed at 250MB/s, but then again some losses were expected.
OCZ 1TB Z-Drive will cost around 1,500 USD, which sounds far too cheap considering that OCZ’s 250GB Vertex harddrives cost $800 each in stores.
