I bought this WD Elements 6TB drive for attaching to a Synology DS220J NAS as a backup service. My DS220J NAS uses DSM (DiskStation Manager) V7.1, which supports backing up of the NAS contents to a USB locally-connected drive. It was important for me to install a local backup service for my DS220J NAS, because I use it as a local cloud facility for storing application files. This is instead of storing these files locally on individual computers and using the NAS itself as backup. This arrangement allows me to share application files across several computers, i.e. the DS220J NAS acts as a central storage facility for all network computers. The WD Elements storage drive fulfills the NAS backup role admirably, with the DS220J DSM software managing backup scheduling ... MoreI bought this WD Elements 6TB drive for attaching to a Synology DS220J NAS as a backup service.

The WD Elements storage drive fulfills the NAS backup role admirably, with the DS220J DSM software managing backup scheduling without placing a burden on the network. The WD Elements drive is woken-up and put to sleep by the DSM software, as required for the backup schedule. As the WD Elements drive is only active for 20-30 minutes, twice a day, purchasing a WD Red disk was not necessary.

After a week of detailed formatting of one of your 16 Tb machines, I found it operated perfectly. I installed about 5 Tb of my data for the past 20+ years and ran it with no problem. I soon bought one of your 18 Tb units, detail-formatted it in a day (using a faster home computer) and copied the same date to it. I now have two machines which PROBABLY will operate forever without any problem; but, if one fails, the other will compensate. Two machines also allow me to work simultaneously on my two Windows and Ubuntu home computers. I am an experienced WD owned, who previously was using two 5-Tb "Easystore" units for my backups, but they were almost entirely full. Before them, I was using a 2 Tb and a 4 Tb Seagate machine. However, years ago, an older Seagate went dead ... MoreAfter a week of detailed formatting of one of your 16 Tb machines, I found it operated perfectly.

The "Yes" "No" buttons above don't really allow for a proper summary. The drive itself is good quality, I cannot fault it, it works great. However the power adaptor is not good quality. I have 2 of these drives now, my first one came with a power adaptor made in Cambodia which is good quality and no issues. However, the adaptor that came with this one is cheap made in China garbage, comes with a slip-on adaptor that goes over the 2 prongs so it'll fit Australian plugs. It will not stay in the power outlet plug when the outlet is vertical mounted, like on a wall or vertical mounted powerboard. It keeps disconnecting the drive from the computer because of loss of power. The only way to use it so it works correctly is have the plug/powerboard it goes into horizontal. ... MoreThe "Yes" "No" buttons above don't really allow for a proper summary.

Probably a cost cutting excercise by WD I guess, as a lot of these companies seem to do, but all they've done is made the total product worse for consumers by swapping to this cheap power adaptor. Would I purchase again? No, not if it comes with the same adaptor I received with this one.
