Customer Ratings & Reviews

My book 4tb external hardrive is very fast and quiet. Ive had it for over 3 weeks and i dont even hear it. Im using ut with the invidia shield as an external hard drive. Im using plex. Everything loads up very fast. I would recommend to anyone for invidia shield.

Works great as an external HDD for my PS4. Was able to buy it during a sale and saved about $30. Only downside is that it requires an external power source, so make sure you have an extra outlet. Good purchase, no regrets.

Easy to use but slow wish the transfer speed was faster still good buy

Easy to use and install.. easily able to recommend this product

This external hard drive is great. Very helpful to save images.

I've had very good experience with Western Digital hard drives over many years. The My Book line of drives for Macintosh have served me well, and Western Digital stands behind them with a strong warranty. I was quite pleased to see this 4TB MyBook available for less than $100 on sale.

This unit works well no problems so far, would buy again!

Bought this For a backup while I was using windows So far it has weathered the storm. It can be formatted to use windows and Mac. No problems like the previous ones I’ve purchased in the past. I would definitely recommend.

Very happy with this as a backup external drive for my iMac at my home. Was able to partition for time machine back ups as well as store files. Scored one on sale so happy especially if it lasts me a few years

It was pretty much plug&play. Computer recognized it immediately, it works perfectly. Would give five stars if it had an "activity" light so one could tell when it was on, and/or working,

While I have used these as external drives, most of the time I quickly pop these apart for the 3.5" drive on the inside. It's takes about 30 seconds if you watch the YouTube videos and they're typically $10-20 cheaper than the internal, plus you get a free USB cable out of it.

I really like the 4TB capacity of this drive, but wish WD would have kept the LED activity light from previous generations. It's a visual reminder that the drive is powered on and let's you see from a distance if it's done copying or not. By leaving it out, probably due to cost, it makes you begin wondering what else they're cheapening up inside the drive.

Good, solid product that is easy to use. For some reason, this Seagate places itself ahead of my boot drive, tho, requiring me to unplug the dive if I powerdown. It is fast, Inuse it to hold raw file images which are accessed by other processing software. Saving and upload is quick.

Works great. Small foot print to keep it hidden or stored away.

Small. Fits on desk perfectly. Out of sight out of mind....

My hard drive new out of the box only came with 3.6 tb of storage available. Not quite the full 4 as advertised (maybe they rounded?) other than that it runs smooth and is very quiet. Things download very fast also.

Backed up my 2TB drive quickly and seems to work great.

Good hard drive and easy to store info. Good price

Seems to be working as advertised. No complaints so far:-)

I needed to upgrade to a new drive to make certain I had one that continued working, and this one is working well enough. Unfortunately it can be a little noisy, but I'm guessing that may be partly due to the fact that it's been dropped a few times. Yet the fact that it's still working afterward is a great plus.
