But a report from The Mac Observer indicated that booting from disk would be supported over Thunderbolt.
Thunderbolts speed will make running an OS from an external drive much faster than previously possible; however, it will still be a while before consumer grade Thunderbolt accessories are available.
Note: iclarified posted that AnandTech received a Promise Pegasus R6 Thunderbolt RAID system and confirmed the news on Twitter.
@anandshimpi BTW, can you boot from Thunderbolt? That is the biggest concern of mine atm.@HellhammerMR yep, it is bootable:)
