HYBRID DRIVE: Instantly add 128GB of lighting-fast onboard flash memory storage to your 15" unibody  MacBook Pro with Retina Display. TarDisk combines with internal volume to add this storage space directly to your SSD. HARDWARE: Seated inside of a precision UniBody Aluminum enclosure, TarDisk takes advantage of next-generation flash memory controllers developed for high-definition 4k filming. The cooling effect of the Aluminum enclosure enables the use of premium, high-density, MLC flash memory modules to be used -- the same as those found in many SSDs. PERFORMANCE: When "installed", performance is matched to the standing performance of your existing Hard-Drive. This is achieved through dynamic storage, allocating frequently used files to your pre-existing Hard Drive and caching any large file before it is written to the TarDisk. With these processes occurring in the background, the user experience is seamless. PLUG-AND-Play: Slide TarDisk into the side of your MacBook computer and you are done. No tools necessary for installation or removal and no effect on existing AppleCare. TarDisk is the worlds first plug-and-play Hybrid Drive: a Semi-Permanent Storage Expansion Drive. SUPPORTS: This TarDisk supports any 15" Retina Display unibody-aluminum MacBook Pro with an SDXC port.
