The CalDigit Thunderbolt T2 Drive Link
The T2 by CalDigit looks like a great Thunderbolt drive. It supports 2 disks as well as SSDs. It’s called a “native” Mac drive which means no special drivers and it’s bootable.
As is popular now, you can sign up for a spot on their waiting list. No price given.
As for Thunderbolt, the speed is nice but it feels like another Apple boondoggle similar to Firewire. February will mark 3 years since it was released and we still have waiting lists for basic Thunderbolt drives.
