Customer Ratings & Reviews

Works great, but the install instructions were non existent. Also there is no off/on button or power light, so you really do not no if it is on or off.

Bought this drive to backup a Windows PC. Ran WD sector test and test failed. Called WD and they said there was probably a bad sector on disk. So I exchanged for another one at Best Buy. Next one passed test and works fine.

Great computer. Works really well and has a fast speed and turn on . I have always liked Dell products.

Bought this to replace an external hard drive where the power supply had failed. Working great thus far.

Bought this to use as an external hard drive tor store pictures while editing in PS and LR. Read/write speeds are good and have no issues with transferring files.

The computers in my home are not networked so this hard drive with enormous storage allows me to store all my photos and mp3s on a single drive then access them on any computer I choose.

It does automatically backup my files most days. However, lately it has been missing some days. On those days, I have to start the backup manually.

Really needed this. I had a another external hard drive and the usb connection came loose and had trouble accessing data. This one seems more durable.

Works perfectly. The new/different pattern on the case allows me to quickly distinguish this external hard drive from my other Western Digital external hard drives.

Looking for extra storage that is reliable. Try the Western Digital 4TB External Hard drive with compatible USB connections. Find many Western Digital External Drives at Best Buy!

Bought two for my kids to store all their music photos so they don’t use up computer space. Plan on purchasing an extra one for myself.

The WD My Book 4TB external USB 3.0 hard drive is great purchase. Plug and play setup. Transfer speed is really good. I was able to replace 2 drives with this one unit.

It works most of the time. Then it says there is no room for backing up the computer's hard drive. However the WD My Book has more than 10 times the space it needs for a backup.

WD makes the best in my opinion. I use this for permanent backups, only plugging it in when needed.

Looking for an external hard drive that will allow me to back up my photos and my videos. In the past Seagate has failed me so I decided to go with this model and I'm very pleased

I like the amount of storage but i have to disconnect it from my Win10 pc often. PC wont boot up sometimes if I leave it connected all the time.

This drive runs cool. I believe it's a WD Blue Mainstream drive inside, but I haven't opened the case to confirm.

This product definitely within the specs required for business purposes. Like the diversity of the Cloud as well as regular backup storage.

Yet another backup for my photographs. Seems I can't have too many. And.....they all work great !!

Am happy with this .. it was preformatted exfat but thats ok works like a charm... the one thing that i really like about it is that it ejects quickly.
