Placing a pair of Indilinx controllers (the same used on the Vertex drives) in an internal RAID is enough to saturate SATA on sequential writes and helps with random writes as well. Adding *another* pair increases random writes even further. These figures show OCZ is working hard to get their internal RAID solution working well with their Indilinx units. Ryan saw the early models of the Colossus in-person at Computex 2009:
We’re looking at a simple 3.5″ form factor SATA drive. The early word was there would be only 2 Indilinx controllers inside, but it seems OCZ has figured out how to shoehorn 4 of them in there. More to follow once samples are available to us.
UPDATE: We did get a couple of clarifications from OCZ on this as well as a few stock images to show as well in addition to my images from Computex above. The Colossus does in fact use a custom PCB design – this is not simply Vertex drives jammed into a 3.5-in hard drive case. For the higher-end Colossus(4x) product it will have FOUR Indilinx controllers each acting as a “virtual drive” working in tandem with the other controllers via an integrated RAID controller. Also, the RAID controller that stripes these logical drives together is from Silicon Image – OCZ seems to have ditched JMicron for that purpose for now at least.
Even more important is this: OCZ is ramping up production and these drives MIGHT be available for purchase in as little as 3 weeks. Pricing is going to be competitive, but not earth shattering:
- 128GB – $299 – $2.34/GB
- 256GB – $649 – $2.53/GB
- 512GB – $1199 – $2.34/GB
- 1TB – $2199 – $2.14/GB
