Excerpt: One of the original 2TB drives failed on a Friday morning. My DROBO is about 3 years old and this is the 2nd drive that I have replaced. B&H advised to get this 4TB drive as a replacement as well as assisting me in arranging for Saturday delivery.
Pros: Easy To Install, Fast, Highly Compatible, Quiet, Reliable
Summary: Do some looking around; there were 4000+ reviews for this item last month; the seller has changed the listing so all those reviews no longer show up.. Just as well; nobody can read 4000 reviews. BUT, keep in mind other sellers offer this drive with a full warranty and Oceanside does not.
