I love that feature because in the past I have had photos and family videos that were lost in the abyss somewhere when we had a power outage. This unit helps protect against such an event. Its price is the same as my old one that was bigger and it works much better. I am very happy with this unit and would buy it again if I need to, and the seller was awesome as well.

Eventually, I tried moving it away from the RAID unit and the noise stopped completely. I only thought of this when I remembered I had a TRS-80 external floppy drive that clicked and whirred every time a fluorescent light above my desk came on!

With 18 different doctors and an extensive history, I can’t take a chance of losing those files. The peace of mind having this stand-alone backup, is worth its weight in gold to us.
