The criticism is not quite understandable to me.

The "normal" hard drive can not use the full possibility of Thunderbolt connection, each should be clear that something has studied the matter. Only SSDs are fast enough to fully unlock the potential of 3.0 Thunderbolt and USB. Unfortunately cost SSD drives several times a SATA disk.
Not without reason, costs the same housing with a 256GB SSD hard drive is more than twice as much as this version with 1TB SATA disk.

Nevertheless, one can use this bundle excellent when they are used for. B. on a MacBook or PC with Thunderbolt port. Since the hard drive is still in a rather significant data values ​​that can be seen better than on a FireWire port.

If someday SSD drives are cheap, the plates one can still exchange.
