3 out of 5 eggsBefore you Buy....

Pros: Fast. Fairly simple installation, with some issues (see below). Not especially fast as an SSD or spinner, it wont win an award in either- but it is both, and in a 9.5mm package... that has value.

Cons: The partitioning software is total junk. I bought a pair of these to put in the same laptop- understanding there wasnt going to be RAID- and the partitioning tool (what others here are calling a driver) that unlocks the 1tb spinner portion for use only noticed one of the drives. Even support at WDC failed to realize it was a failure of the tool, not the drive- and so just before I dropped in the box for RMA, I tried to partition the drive we all thought was broken by itself while not in a computer booted to the other drive- and it worked fine. I can understand no RAID, but it also wont span or pool under windows, which is a bit cheesy, IMHO. If it worked for storage space pools under windows 8, I'd give back a star. If the partitioning tool didnt make me work for 24 hours to have two functioning drives, they'd get back another.

Other Thoughts: New Egg was wonderful when we thought I had a bad drive.

1 out of 5 eggsNot worthy of WD Black stellar reputation.

Pros: Good disk copy software. Pretty package.

Cons: Extremely slow. I was expecting a drive worthy of the WD Black name. This product falls way short of that.

Other Thoughts: I would not recommend this product to anyone expecting speedy performance. No ! I would not purchase again.

Manufacturer Response:

Hi William. Thanks for the review. I’m sorry to hear about the slow performance that you experienced with the drive. We do have a firmware update that improves power management and spinup/spindown. Sometimes there could be a delay as the drive spins up, which could cause performance to be a little slower. I included a link to the firmware update below if you wanted to try it out.

5 out of 5 eggsDon't call me a Hybrid

Pros: * Easy to install
* Reliable
* Inaudible
* Fast

Cons: * Its pricey
* 1TB Might not be enough anymore

Other Thoughts: I have been using this drive now for almost 2 months. It has been running 24/7 since it was installed. So moving along, this drive isn't like a hybrid. After installing the dedicated drivers from WD it actually shows up as 2 separate drives: a 120GB SSD and a 1TB HDD. If you don't install the drivers it will only show up as a s single 120GB SSD. There is one thing I should point out here and that is while the 1TB HDD is visible in a Windows environment it wasn't visible in the BIOS. Not sure if that is an isolated thing but I am running the latest BIOS in my ASRock Z77 Pro3.

The idea with this combo drive is to install the operating system and core programs such as Office on the SSD and everything else on the HDD. I installed Windows 8 on the SSD and installed Steam, Origin and Uplay on the HDD and its working great. Booting into Windows 8 is a breeze usually taking 7-10 seconds. Running through Windows 8 is smooth and fast as expected with an SSD. Remember when installing your gaming software like Steam to select the HDD or else you will fill up your SSD really fast. I also created a media folder on the HDD and loaded my movies, music and personal photos. Lets move on some speed tests and a final verdict. These speeds were taken from the SSD.

Sequential Read: 321MB/s and Sequential Write: 110MB/s. These aren't mind blowing by any stretch but they are respectable for what this product is. Daily users will be satisfied with more than adequate performance. The drive as a whole is inaudible. Using it for almost 2 months now I have had no issues to speak of. Overall I am very impressed and I am still using it as my daily driver in my gaming machine. If you are someone that doesn't want to hassle with buying 2 separate drives then this is a good choice but only if you can find it for around $200. I have a hard time recommending it for anything above that price. You can easily find a 120GB SSD and 1TB HDD for roughly $160 combined if you look around. That isn't to take anything away from what WD has done with this combo drive. It simplifies using an SSD with HDD together and its an excellent choice for someone that doesn't want to haggle with 2 separate drives. Its the first one I have ever used that has successfully combined 2 drives into 1. Backed by a 5 year WD warranty which I have personally had to use on previous WD products you are in good hands as they are one of the best in the business. Aside from the price tag its a 5 egg item.

5 out of 5 eggsSo far, it's great!

Pros: 2 drives in 1, a SSD to boot to, and 1 TB of hard drive space for data storage. Seems fast, installed easily.

Cons: I think the only con I can say is the price, but since this is a new concept, I am sure they are recouping R&D costs. Also, the fact that you do not see the 1TB until you install the driver can be frustrating until you read that this is required.

Other Thoughts: I think most laptop internal SATA ports do not support port multipliers, so I think this is the reason you need to install the driver to see the 1TB of space. (so the internal drive logic does the port multiplier for you) That is my theory at least. Luckily, when I used an Acronis boot disk, I was able to see the 1TB of space, so this worry was not an issue (I usually image from a boot disk, even though Acronis 2014 does not require you to use a boot disk to backup the boot partition). I have not ran my benchmarks, but the boot time seems just as fast as my Samsung 840 I replaced. I had a Samsung 500GB 840 drive that this WD Dual Drive replaced, the Samsung was almost 1/2 full. I did not "need" this drive, but the idea and concept made me want to try it out. I had the Samsung partitioned as 100GB/400GB, so it was easy to image this over. The drive comes with Acronis to adjust the partition sizes and clone your existing partitions. Also available are the firmware update software and some other diagnostic utilities, all free of charge. My final config was all 120GB to boot part, 700GB for data, and the final 300GB for the Acronis Secure Zone to store my backups. If the price drops below $200, I would say this is "THE" laptop drive to have, getting both the space and fast OS boot. With 120GB, that is enough to hold Office and the OS, plus a few games like my WoW and WoT installs. Even as it is now, this seems like a great drive and a well thought of idea.

5 out of 5 eggsGreat Drive!

Pros: This is a great drive,
-Easy to install
-Easy to setup
-Fast SSD+ spacious HDD
-Mildly increased battery life.

Cons: None
It runs perfectly smooth.

Other Thoughts: Used to upgrade my aging HP DV7 4100 laptop, from a slow SATA 2 HDD.
Wanted to copy the original windows partition from HDD, but was not able to shrink partition to a manageable size before transfer.
Had to fresh install windows using a spare install disk, and the original product key, I was eventually forced to activate by phone, but it has run perfectly since.

It's increased boot speeds from well over 1 minute to about 20 seconds and completely rid myself of HPs "bloatware" even though I was able to install it's Drivers from the HP website. Still have close to 50GB of space left, and an extra 30GB left available for a future Ubuntu install.

Very happy with this drive and is great for anyone needing the speed of an SSD and space of an HDD.

5 out of 5 eggsVery Pleased!

Pros: Fast boot up and operation. Quiet. Painless to install.

Cons: Though I had plenty room to install my many programs on the SSD, I would have preferred to have at least 200GB on the SSD for the room.

Other Thoughts: I just completed installing this WD Black-2 Dual Drive onto my Dell XPS 1645 laptop and am very pleased! As indicated in the video on the WD site, you can either do a clean re-install or do a clone of your existing HDU. I opted to do the clean install. Tho I knew it would take considerable time, I'm glad I did. The 120GB SSD comes up as the default. I installed the OS to the SSD, then put the "key" that comes with the drive into a USB. It took me to their site and automatically downloaded and installed drivers to recognize / set up the 1TB Black 2nd drive. I created the same type of folders on the 2nd drive as on the primary (i.e., Program Files (x386), Program Files, Users, etc.). I reset my library folders (Win7) to folders on the 2nd drive (simply right-click on your user folder [e.g., Documents, Music, etc.], click on "Location" and select a folder on your 2nd drive - it migrates everything their automatically). You can do the same for the "Public" folders but have to boot into Safe Mode to modify these folders. I copied all my data from old drive (WD gives you a SATA to USB pigtail to use) to the new folders on the 2nd drive (i.e., Documents to Documents, etc.). I then re-installed all my programs. I even reset the temporary folder (under System folder in Control Panel) to use the 2nd drive. I have a lot on my laptop and still have nearly 50GB left on the SSD drive! It boots much faster and runs remarkably smoother.

5 out of 5 eggsTotally Awesome.

Pros: Speed, storage capacity, size.

Cons: Price. (For now...)

Other Thoughts: This is an incredible evolution of SSHD technology. Before this drive if you had a laptop with only one drive bay you had to either settle for an average sized SSD or get a huge HDD that was sluggish by comparison. Now you get a perfectly sized SSD for OS + lots of programs and tons of storage for everything else! It comes at a steep price for now but for early adopters with a laptop that has only one drive bay but a screaming processor and 8+ GB of RAM, this will future proof that thing until all of its hardware is obsolete... The included Acronis was ridiculously easy to download and install and cloned my laptop's SSD in about 5 minutes! Then the WD software enabled the 1TB HD and I am cooking with gas with a laptop that appears to have (and works just like it has) two hard drives! It boots just as fast as the SSD alone, but the WIE went down in Win7 from 7.8 to 5.9... Odd, it must be taking the 5200rpm HDD into account because performance has not been hurt in the slightest and programs load as fast as any SSD I own. Everyone else has done file transfer speed reviews so I'll just let you read their reviews for the numbers. This drive is a dream come true. I used a WD Raptor for almost 6 years and loved it because that sucker booted, ran programs, and transferred files like no other HDD (still have my whole OS on it in a drawer for emergency recovery) but went over to other brands' SSDs when they got cheap. Now I can see if WD Black Squared is as reliable as the Raptor. IF you have the money and the laptop for it, buy it. Period.

1 out of 5 eggsIncompatible with my laptop?

Pros: If it worked, this would be a great combination of SSD for the OS partition and spinning disk for large storage capacity.

Cons: After three+ weeks and one RMA'd drive I've yet to get it to work properly in my laptop, an Acer 3820TG. Specifically, the drive fails the WD Data Lifeguard express test with a "drive reset" error, hibernating causes a blue screen, random freezes occur and chkdsk tends to run at boot and find errors. While timely in their responses, WD support has not been very helpful (the latest after the new drive showed issues: "Please try with a different SATA cable or port" which is a pointless suggestion on a laptop that doesn't have SATA cables and has only one drive bay).

Other Thoughts: When imaging over my existing install didn't work for the original drive or the RMA'd one, I decided to do a clean install of Windows 7 x64 Home Premium. After this the drive actually passed the Data Lifeguard drive "Express" test which it wasn't doing before. It also was able to hibernate. Once I installed my graphics driver, however, the drive went back to failing the test and blue screening on hibernation. So, I'm thinking that there is an incompatibility with my system. WD Support is offering to RMA again, but I don't think my problem is defective drives.

Overall summary: This drive may be a great compromise between space and performance if you can get it to work with your system (note some laptops are listed as incompatible, but mine wasn't one of them).

Manufacturer Response:

Hello bjohanso,
Thank you for your feedback as it is greatly appreciated. We are sorry to hear of the difficulties experienced during installation and configuration. The Blue Screen and hibernation issues may not be due to the Black2 drive, especially if you didn’t encounter the issue until the video driver was installed. We would suggest trying a different driver version of the video card if possible. Usually it can be downloaded from the computer/video card manufacturers website and they typically have different versions, or “revs” available. If the driver came from Windows update try the manufacturers site and get the latest version from them. In addition, we are always here to help so please do not hesitate to contact us via phone or email at the following link: and mention this Newegg review so we may route your case appropriately.

4 out of 5 eggsCool concept but only for primary hard drive

Pros: Preliminary note:
To test this I used the USB cord provided with a USB 3.0 port. I use Windows 7 64 bit already running a SSD for my primary drive. I did not install a new OS on this drive, I was trying to use it as an expansion drive (not great for that, read cons).

-Fast SSD
-Easy installation (with new or old OS)
-Cool concept
-Good as single drive option
-Good USB cord

Fast SSD:
Here are the average benchmark tests.
Large files (1-3 GB): 450-750MB/s
Small files (0.1-15MB): 70-130MB/s

Easy installation:
The drive with the software gives you 2 options. You can either install your OS from scratch or you can even clone your existing OS. I would personally recommend reinstalling your OS but I doubt you would see a huge difference with which ever option you choose. I would suggest (if you don't want to reinstall everything) to clone your OS and if things start getting funky, just reinstall your OS at that point. No reason to try to prevent problems that may not happen.

Good as single drive option:
If I were to get a new laptop, I would use this drive. It is a great idea, having a fast OS portion with large storage space. Even if I had a place for 2 hard drives, I would probably just use this one (and maybe the one the laptop comes with as a secondary).

Cons: Overview:
-Very specific use
-Cannot use as expansion drive

Only use:
I tried using this as an expansion drive for my already installed OS. Unfortunately, I could not install the software to let me use the HDD portion of it, only the SSD. It appears that you can only access the HDD portion if you have the OS installed on the SSD portion, otherwise the installation software cannot find the HDD. Since this can only be used as your primary drive, I do not know why they have a USB cord that comes with it. Just about every one would put their primary hard drive inside their computer.

Other Thoughts: Overall, I do like this drive but you basically need to use it as your primary hard drive. It is a great, fast, and large single drive option but I am not sure if that can justify the price for everyone's needs.
