Customer Ratings & Reviews

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

Wanted a powered external drive for Mac Mini Time Machine backups. Well, though I do hear some noise during disk access.

My WD 4TB external USB 3.0 has been okey so far, not as fast as what i was expecting but manageable and its quite (compared to my other external drive). Keep in mind it needs to be powered separately to work.

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

Easy to use product. Just plugged into my laptop and was able to back-up my information immediately.

Works great for achiving my desk computer and laptop. Still have a problem with Norton backups with a Netgear Router with USB Port. I sgreat value for the money and it may just be time to replace with acompatible Router.

I have used it on WIndows 7, when I connect using usb hub it didn't start up. I had to reboot computer and tried again. Not sure why it doesn't start immediately. Maybe learning curve but as usual no booklet to seek help.

Needed a larger drive for my Xbox One X. Data transfer from smaller drive was smooth, no issues. I'm optimistic that this drive will hold up long term.

I needed some extra storage and these 4tb My Book drives offer some good performance and capacity for the money, especially when you find them on sale.

I have a couple WD external hard drives. This one is just like the others and gets the job done.

I had a hard drive starting to fail so I purchased this to back up my data. It connected easily, windows found it immediately, and the data transfer was fast!

for being a mechanical hard drive ,it is the fasted i have ever seen .speed is around 180's to 190 mbs. even out performs the passport from W.D.

I am a big fan of WD drives and this is no exception. My only complaint would be that Western Digital has eliminated the power/activity light on the drive. I really don't understand the logic behind that decision.

Works great! I am still trying to fill this thing up with xbox downloaded games!

I love the product, if anyone is interested in this product you won't be disappointed.

After reading all the reviews, I bought this drive to add capacity to my Xbox. Setup was easy, response time is great. Strongly recommend this device.

This hard drive doesn’t take power or I should say use electricity makes it easier on the power bill and also unhooks and move to another computer making it great to use work on the hard drive on the go

Makes noise when backing up that normal. Periodically make noise without backing up, is this normal?

Works the way that it should, can't think of anything bad to say about it...

Really good so far. Fast on 3.0, which helps for editing video, etc. Always trust WD Black.
