Thunderbolt Supports Booting From External Disk
With Apple's Thunderbolt cable and the first third-party drive systems hitting the Apple Store yesterday, Apple posted a few support articles outlining some of the Thunderbolt functionality, but failing to disclose any booting capabilities and thus leaving potential customers still in the dark about compatibility.
It now appears, however, that we do have confirmation that booting over Thunderbolt is supported, as we received word yesterday from a reader who had received multiple confirmations from LaCie representatives that the feature will indeed be supported. Meanwhile, AnandTech has already received one of the new 12 TB RAID systems from Promise and confirms that booting over Thunderbolt is supported.
