TarDisk Pear is an internal hard drive upgrade for Macintosh Computers. Pear provides a unique implementation of a hybrid drive which combines a specially designed solid state TarDisk and your existing solid state drive to provide a single managed logical volume on your MacBook. As the first product of its kind to offer the public access to plug-and-play hybrid drive technology, TarDisk Pear is a combination of the custom designed TarDisk Solid State Disk Hardware and the TarDisk Pear software package installer.
Above is an excerpt from Wikipedia showing a DualDrive Hybrid Drive system similar in layout to a Pear'ed TarDsik
Once TarDisk is installed and "Peared" (a.k.a. the Pear Software is run on a host machine), the Solid-State hardware of TarDisk is merged with your existing Hard Drive to form a single Macintosh HD.
Performance tests taken with BlackMagic, GeekBench andNovaBench, intended to quantify as many metrics as possible both before and after Pear-ing, show equivalent or slightly improved MacBook performance.
TarDisk Pear establishes a new class of hard drive options to suit your digital storage needs.
