Enjoy award-winning ultra-efficient Block Management & Wear Leveling technologies that virtually eliminate any speed reduction over long term use of the drive. And with no moving parts to break or fail, the OWC Mercury Legacy Pro SSD offers uncommon ruggedness for notebook users with up to 100x greater reliability than traditional hard drives.
The "Swiss Army Knife" of Disk Connectivity…
The NewerTech USB Universal Drive Adapter is the perfect tool for accessing bare drives without having to install them into a computer or drive enclosure. Being compatible with almost any 2.5-inch, 3.5-inch or 5.25-inch drive from the last 15 years makes it the go-to tool for accessing data on IDE, ATA, ATAPI, and SATA drives.

It's the ultimate add-on to any workbench, small enough to travel in your toolbox or tuck away in a drawer so it's ready whenever you need to access drive data via USB. The Universal Drive Adapter is the "must have" universal data access tool.
