I've done some searching and reading both here and Google but haven't found the answer. I also read the specs for the Seagate Backup Plus Thunderbolt at Seagate.com but didn't find the answer. I'm trying to determine if the Seagate Backup Plus Thunderbolt like this one at Amazon.com will work with an SSD larger than 512GB. I'd like to put a Crucial 960GB SSD in the Backup Plus Thunderbolt adapter and connect it to my mid 2011 iMac 27 to use as my system and storage drive in place of the internal HDD. I'd then use SuperDuper to backup the SSD to the internal HDD in case of a failure. Any advice on the max capacity SSD I could use would be appreciated. Thanks in advance.
