Warranty

The best warranty is one you never have to use - but should the need occur - we're proud to provide a superior level of support and service coverage to our customers.

90 Day OWC Replacement Warranty
OWC is proud to offer an extended replacement window of 90 days on new internal hard disk drives. Once a return authorization number has been issued and we receive the problematic drive back, you will get a brand new replacement drive, rather than a factory refurbished drive.

5 Year Toshiba Warranty
After 90 days, the drive is fully backed by the manufacturer to be free from defects in material and workmanship for the remainder of the five year warranty period.

Rating: 5/5 So far...excellent. November 21, 2017 I put this HD into the case that looks like the MacMini. I chose this drive because of it being an Enterprise drive. I looked at overall reliability on the interweb and this brand has the best reliability. I installed it, formatted it and started downloading my photos from my Master external dual drive "Mr Big". No problems. I rotate this drive with one in the Bank's safety box.

Rating: 5/5 Great for storing valuable data February 20, 2017 I bought a pair of these enterprise class HDD's to install into a RAID box. I'm a firm believer in backing up my data (photos, music, videos, applications ... everything) weekly. These drives are designed for use 24/7 in a mission critical environment, and that's the kind of protection I want for my personal data. Overkill? Maybe. The cost is a small price to pay for the peace of mind.

Rating: 4/5 Need a new Elite Pro enclosure October 8, 2014 I purchased this HD to replace a smaller HD in an older Elite Pro enclosure which I found out after receiving it, that the older enclosure doesn't support more than a 1.8 TB drive, so after talking to customer support, I purchased a new enclosure and it now works well. It would be nice if OWC would note this on their website page with a description of the drive!

Rating: 5/5 One sweet drive! August 24, 2014 This is my third internal drive and I suspect it will be my last. Since the second internal drive failed while in warranty, I decided to replace it with an enterprise-class drive. My fear was that my silent iMac would now have an audible drive noise, but that fear was misplaced. Yes, you can hear it moving heads during access, but there's no spinning disc sound. It's fast, it's big, and it has a long warranty from a company I trust.
