Earlier this year we had the opportunity to review the Seagate GoFlex Thunderbolt adapter designed for Seagate's portable hard drive range. Seagate has since released the GoFlex Desk Thunderbolt adapter which can be used to upgrade its USB 2.0 and USB 3.0 desktop GoFlex drives. The concept is a good one - pay a little more for the Seagate GoFlex drive upfront, but you then have the flexibility to upgrade to a faster I/O as the technology becomes available. So is it worth upgrading your USB drive to Thunderbolt and is it worth the $190 price of admission?
