OCZ today formally launched the Colossus, its first solid-state drive line aimed primarily at the desktop. The 3.5-inch SATA II disks are designed both to fit directly into desktops without a mounting kit but also to provide performance above even some notebook SSDs. OCZ has raised its speed claims beyond early estimates and now says that the fastest Colossus drives reach peak read and write speeds of 260MB per second and sustained write speeds of 220MB per second.
