OCZ Colossus SSD boasts RAIDed drives

The OCZ Colossus SSD implements two RAIDed drives on a single PCB.
These sort of drives were earlier seen for the high end systems, specially servers. However, OCZ has now moved these drives for the consumer market. The drive actually implements two SSDs as a single drive in a 3.5 inch package. The main idea is to add their data bandwidth to obtain high throughput. The controller on the drive is rated at 260 MB/sec, which will be sustained by the drive.
The main bottleneck for the drive is SATA II 3Gbps interface which saturates at around 260 MB/sec. However, with the new 6Gbps SATA controllers, such drives might be able to produce higher data rates.
More extreme solutions can be made with this idea such as Colossus 4X and 8X that can produce mighty data rates. However, due to increased chips and complex design, the prices of such SSDs becomes even higher.
Initially, the available capacity of these drives varies from 128GB to 1 TB. However, at $299 for the 128GB model, these drives are still a luxury which many can’t afford.
