FUD Zilla spotted uber fast OCZ Vertex 2 solid state disk prototypes at CES 2009. During a demonstration, the drive reached a read speed of around 535MB/s and write speed of around 470MB/s!
The site says these drives will be launched later this quarter, but you'll need to wait for SATA 3.0 as the SATA 2.0 specification can't do more than 300MB/s.
This is specially the case with big files and in reality at this speed you might copy a 20GB file in just 41.66 seconds, and we are sure that video editing guys are going to love these numbers. In order to achieve thee speeds you will have to get to SATA 3.0, as SATA 2.0 is maxed out at 300MB/s per device. SATA 3.0 on the other hand gets you all the way to 750GB/s which will be enough even for Vertex 2.
