OCZ to release 1TB SSD this month

Colossus solid state drive has up to four controllers

OCZ Technology Group Inc. said today it will release its Colossus solid-state drive (SSD) in the next couple of weeks, delivering the first 3.5-inch form factor SSD with 1TB of capacity.

The drive is aimed at external storage and desktop computing applications, and should be particularly attractive to gamers because of its high capacity and impressive performance.

Like OCZ's midrange, consumer 2.5-inch Vertex SSD, the Colossus uses an Indilinx controller. But unlike the Vertex, the new Colossus drive comes with an option of two or four controllers, and can be configured for internal RAID 0 for data resiliency.

OCZ said that each controller in the Colossus will act as a virtual drive, working with the other controllers through a separate RAID controller from Silicon Image Inc.

Using ATTO Disk Benchmarking software, in a four-controller configuration the Colossus has a maximum sequential read rate of 261MB/sec and a maximum sequential write rate of the same, OCZ says. Using the IOMeter benchmarking tool, the drive turned in 223MB/sec sequential read rate and 224MB/sec sequential write rate.

Bottom line on performance: No matter how you look at the numbers, this drive purportedly screams.

The Colossus will be available in 128GB, 256GB, 512GB and 1TB capacities for $US300, $US650, $US200 and $US2200, respectively.
