Customer Ratings & Reviews

This external hard drive has preformed excellent over the first 30 days of operation.

I got a 2 x 8T to replace my previous one, one drive of which failed, and apparently, had not been mirroring. The price makes it attractive, and WD has a long reputation -- I've used their drives over the years. Here's the thing, if you know about RAID, how it works, what to expect, etc., this could be great solution if you don't want to spend the BIG money. But, be aware, it comes with no software and no manual. So your first task will be to search for those. The user manual on the WD website is OLD (the list of operating system compatibility ends at Window 8 (pre 2015) and Mac OS Mavericks (2013)) and the manual references obsolete WD software to manage your drives (WD SmartWare). So, you are on your own unless you already know what you need to do. So, this might suit you, otherwise, be prepared to educate yourself. BTW, WD support never replied to my support request.

I can not say enough. I bought this drive and am very happy. It performs very well and without issue. The speed is comparable to having the drives internal to my pc. Never have I found that. I get the same speed regardless of the connector or cable I have used. It is roughly 200MB/s. The USB hub feature works great. Just remember to have the main drive recognized before you connect your external drives. The software, everything is top notch. Came with two RED NAS drives with the 256MB cache made in Thailand. It is a newer RAID software so it did not accept a WD RAID built in another WD device. That was not expected.

It's an external hard drive and does what it is supposed too. This is my 3rd one and it works great. The first two where of the older design. The first thing I did was change the configuration to RAID 0 so I have 8TB mirrored instead of 16TB striped. This gives me data protection without having to run a separate data backup process. Data transfer is fast and they have been very reliable. They are on 24X7 and I have not had any issues since purchase a couple years ago.

I bought this to replace a pair of 6TB drives that I had been manually keeping synced. Seemed better to have a mirrored drive and more space at the same time. Now I have one cable and one power supply. I haven't had this unit long enough to truly rate it. However, this is my 2nd one of these. I bought one a year previously. I use this first one as my media drive. After 10 months it reported that one of the drives had failed. As a mirrored unit, it continued to work with no loss of data. But I had no clue which drive had failed. The WD Drive Utility would not tell me and WD Support told me it was supposed to, After too much time on the phone with the helpful Support person, he decided I should return the drive. I backed it up, shipped it to WD, and received a "new" refurbished one in return. I give these drives a good rating since I lost no data and WD honored their warranty. I also like that the WD Drive Utility provides so much more information that you can normally get for an external drive on with MacOS.

I bought this as a backup drive. When it is formatted in RAID 1, there is about 7.5TB of space. For me that is plenty. In terms of value, most people will want to stick to a lower capacity version unless they absolutely need all of the space.

this is a very good hardrive doesn't overheat much and it has tons of space

If you need lots of storage or solid direct attached backup solution this is it. Can be set as RAID 0 or 1. It’s data transfer rate is significant with a USB-C interface.

Easy Setup. Easy Storage. Raid 1, Safety for all my digital pics. Good product.

Worked without a hitch. Fast. Included all necessary cables. And VERY good NAS Red Drive included. NOT a cheap one.

After years of dealing with multiple external hard drives to back up 7 TB of data (plus, more hard drives to backup my backup), I love the RAID system! 1) My Book duo gives me the storage capacity I need with fewer cords and less required plugin space than multiple external hard drives. 2) The ability to set up a "mirror" effect so the second hard drive automatically backups the first hard drive is pure genius, thanks to the RAID system. 3) If one hard drive dies, I can remove it and install a new drive. 4) Plus, this system seems to transfer data faster than the 8TB or 10TB external drives I used in the past. All in all, I'm a happy camper :)

The is super fast USB Type-C storage and a lot of space with 16 TB's. I transferred data from 8 TB's on the old system, and transfer speed was amazing!

This large drive dies offer lots of storage and the downloadable software allows great options for back-up and drive synchronization. The 2 additional USB ports on the back Allow for even more redundancy if you decide not not oration the drive and use a raid array. The only down side it the noise. Not so much that is a distraction with quiet music playing but it is noticeable when the drive is being accessed.

If you’re looking for redundancy or simply a very large storage solution, this RAID is an affordable option. However, there are faster competing products out there for performance driven applications. My results on transferring a 480GB file via USB c were average in terms of speed.

Pretty happy with the speed and durability of these driver. My only complaint is they are a little expensive but have been great to work with for an edit drive.

I purchased this hard drive for the RAID configuration. I purchased the 16 TB version. Setup was easy and quick. It has a USB C connection which is very fast for data transfer. I’ve connected this to my existing NAS and it works like a charge. There is a pulsing LED light on the front of the device when data transfer is happening. Finish of the case is classy.

Works well once going, but after reboot of the computer, the drive is not reconized by the system until I unplug the drive from power, wait awhile, and power it up again after the computer is fully booted up first. Does not work to just unplug usb cable and an plug back in. Drive itself has to be restarted to work. Not a huge thing for me since my computer is mostly running all the time. Otherwise, works well once recognized. A ton of storage space.

Here's the deal - I own the previous 12GB 3.0 USB model which gives a Write/Read speeds of about 180mbs/190mbs reguardless of cable length - Now this drive has USB-C and isn't thunder bolt you get about Write/read speeds of 220mbs/240mbs only if you use the 1meter gen 2 cable. If you use a longer cable - speeds drop to around write - 20mbs/ read - 30mbs.... USB-C - the only advantage of theis drive is the USB-C connection, go buy a true Thunderbolt 3 drive which I did after I returned this.

Lots of storage and great backup solution. Easy to setup and use out of the box.

Works perfectly well, silent enough, fast enough for what I needed it.
