Accessory maker Qnap is showing a prototype of a four-bay Thunderbolt JBOD drive case at Taiwan's Computex trade show. The JTB-400 is capable of holding either 2.5- or 3.5-inch drives. No hardware RAID controller is installed, and the SATA bridgeboard is controlled with a Marvell controller. Pricing has yet to be announced for the rollout of the chassis, expected in the third quarter.
