Fast, somewhat quiet, and basically what I look for in a drive. But, it’s missing a tool to update it’s firmware, I’m on an old firmware, and I don’t seem to be able to find a way to update the firmware even though they have released a .bin file with the latest firmware for it.

I have 5 of these running in my Synology DS1520+. I used WD Developer tools to format them to 4Kn Native disks which improves the performance even further in the NAS. Excellent drives. No DOA.
Mario Mueller (verified owner) –
Great drive with a lot of capacity at a great price.

As always Western Digital rules in the HD Department!!!
Ava Crooks (verified owner) –
Can be formatted with WD tools to native 4Kn. Huge performance gains in the NAS with this setup. More reliability than WD RED Drives.

I ordered four drives for a NAS, and the worst I can say about the drives so far is that they’re remarkably loud. If you’re not running these in a rackmount server they’ll probably be the loudest part of the system. Otherwise, they were recognized by the system and have comparable performance to other hard drives I’ve used, and contrary to some of the other reviews all four of my drives had full warranties. I would buy these again, under the provision that they’re not near my desk.

Moving from 3x8TB 5400 to 2x18TB 7200 is a modest bump in space while reducing drive count. Had planned to use 3x but B&H limited purchase to 2 and I was on a time crunch. The amount of noise these drives make is double the slower drives. They are also faster and more spacious, so it’s a mixed bag. If they didn’t live in my office where I spend most my time I’d probably like them more.

For $500 I got 18TB of fast and expansive storage – using in my Drobo to give me more space before I transition to Synology. So far it is quiet and running smoothly
