Western Digital acted on a two-month promise by shipping its range-topping MyBook Thunderbolt Duo drives. The desktop external disks use the headroom of the 10Gbps spec, along with RAID, to supply speeds faster than most individual internal drives, even on a system like a MacBook Air. In a hands-on (above) with a RAID 0 stripe, we saw real speeds of 750MB per second in reads and 640MB per second in writes, rendering it faster than a high-end solid-state drive.
