    A good purchase. I wish more were available.

    This was a good and affordable replacement for a failed hard drive. I needed a quick replacement and this fit what I needed. I've been buying from OWC for many years and you guys are the first place I go to EVERY time. Thank you for all that you do. I will be back for more, of course!!! (You even put a big 'ol red heart on the packing before shipping)

    I would recommend this product to a friend!
