DDE Thunderbolt SSD

I use a MacBook_Pro Early_2011 limited to USB-2, but with a Thunderbolt port. I substituted my original HDD trays to a Crucial SSD 2.5 "1 TB. In order to have external media (DDE) a clone of the volume of my OS" Yosemite 10.10 "and other OS bootable, which do not put forever to load via the combination: HDD-2 x USB, so I made the emplette this DDE: x Thunderbolt SSD Lacie.

Excellent results: starting the clone on the SSD of this DDE_Thunderbolt is almost as fast as my original OS on rmon internal SSD SATA connection, 10 "near it would be possible for someone whose non handyman. HDD would be released and would like a bootable external system that does not put forever to load and where the read / write process have a decent speed, to use such DDE without seeing a difference with an internal SSD. Of course, compared the OS of an original internal drive remained HDD, this SSD external Ssytème x Thunderbolt would be incomparably faster to use.

The only criticism that can be done to this machine is its price, more than pretty - so I was led to buy the product "new opportunity", which enabled me to get it almost half the price. Given this cost, the purchase of the DDE is unrealistic for a single use document storage (texts, images, videos). By cons, it is advisable for any need of a high-velocity external media: bootable system and / or storage of very large files that have to be operated by powerful internal software OS without loss of efficiency. It can, from this point of view, be regarded as the equivalent of an internal SSD with no significant differences in velocity.
