Answer to "Upgrade HDD to SSD"The first linked Thunderbolt enclosure, the Seagate Backup Plus Portable Thunderbolt Adapter, is limited to ~320 MB/s read speed and ~380 MB/s write speed. For me, this was much faster than the base 1TB 7200RPM HDD; however, I bought the brand new Samsung 850 Pro, which is rated roughly 550 MB/s read and write speeds. So, keep those limits in mind when buying a thunderbolt adapter. I cannot comment on the Delock. I read that the Lacie Thunderbolt drive had a much faster I/O limit, and one just removes the original Lacie HDD included inside the enclosure. I'm researching now wether or not I can just remove the included 1TB HDD and replace it with my 2.5" SSD with the appropriate 2.5" to 3.5" bracket adapter. I'll update here.
