If at the time you bought a MacBook Pro Retina or a MacBook Air but fell short in terms of storage, the Transcend company has already announced the launch of its upgrade kits JetDrive SSD for MacBook Air and MacBook Pro Retina Display.
The JetDrive kit is designed for those who seek to improve performance and the ability of your MacBook in addition to including an external case to insert your 'old' SSD easily and quickly and thus turn it into an external USB 3.0 drive.
First of all, also clarify that they are designed for the generation that still used the SATA III interface in contrast to the models newer that use PCI-e.
This leaves the read and write speeds at about more than a respectable 560 MB / s, which I know situates a point above what the standard ones provide us.
Upgrading to a Transcend SSD JetDrive translates into faster boot-up and access times, while offering a pretty decent number of memory reads and writes to memory degradation. On the other hand, the newly introduced SSDs will be available in capacities up to 960GB offering the perfect combination of speed and storage capacity.

In just a few simple steps, our original SSD is installed perfectly and the old SSD or HDD can be transformed into a new elegant USB 3.0 external storage device for storing and backup documents such as photos, music or movies. The housing is made of aluminum and this results in a design that is strong, ultra light and easy to transport as well as including a practical travel bag to protect the unit against scratches during transport.
Last Transcend you have not forgotten to include a software to enable TRIM on the SSD and thus 'avoid' as much as possible the degradation of the drive due to the number of writes and reads on it.
