5 out of 5 eggsAmazing laptop drive, Perfect functionality

Pros: The drive works wonderfully. Initially installing the OS, the computer will only see the SSD so you don't have to worry about installing it on the mechanical drive accidentally. It requires Western Digital software to enable the 1TB HDD which was a quick and simple installation (less than 5 minutes), and I've never been bothered with it since. Having an SSD on my desktop, I will say the bootup speeds are pretty much identical around 15-20 seconds.

Ascetically speaking, the drive looks wonderful and the packaging is great (not that you see it in a computer). Comes with a USB to SATA/Power Connector adapter so you can pull files off your old laptop drive if you need to.

Cons: None for my uses. I have heard that the SSD on it must have the OS installed on it for the HDD to be accessible. So Using this as an expansion drive would not work well, but that isn't the purpose of the drive.

Other Thoughts: I used this to replace the drive in my laptop that was damaged and causing all sorts of issues. Was originally going to just buy a 250GB SSD, but this is much better and cheaper.

4 out of 5 eggsWestern Digiral Black Squared SSD/HDD

Pros: Using an SSD for the OpSys greatly improves computer performance as would be expected. Boot times are much shorter for example.
Since most laptops have only one drive bay (some exceptions), if you want to have SSD performance and lots of space, there are not many reasonably priced options.
By placing the OpSys and programs on the SSD portion of the drive, you get significant performance over any regular rotating disk laptop drive I have tried. Data such as a Word document for example can be stored on the 1 TB rotating part of this drive, and you give up very little in performance vs. buying an much more expensive large SSD.

Cons: As delivered, the drive spins down almost immediately after accessing the rotating part of the drive. It is then very slow accessing data when it has to spin up each time you want some information on that part of the drive. This is solvable to a large degree by running a firmware update available from Western Digital. However, this update must be run by DOS booting the computer so you have to make a DOS boot-up USB drive, reset any BIOS settings to allow this boot to occur, make the update, and then reset everything back to normal. If you don't mind taking this on, then the drive is a good solution for fast speed and large storage for a laptop. (minus one egg)

Other Thoughts: At full list price, and based on the space needed, there may be some better options. If you want / need the full 1TB of rotating drive space plus the120 GB SSD for speed, it is a good solution but only with the firmware update. Otherwise data access is far too slow.
Also be sure that drive access in the laptop is reasoale before taking this on. For example, some of the new HP laptops no longer have user changeable HDD's. In these, drive change out is a major task.

1 out of 5 eggsDead after a week

Pros: Great Idea! loved the drive while it was working

Cons: Drive died after about a week of use - Was running win 8.1 no problems and then boom! all i could hear out of the drive was the seek arm making the infamous "clicking" noise - Would be cool if the HDD fail the SSD still worked but now i cant even get back in to windows

Other Thoughts: I am a systems admin and i was very excited for this drive - I tested a Hybrid drive and was not impressed - i do store alot of data on my laptop so i didnt think a normal SSD would work - so lets test out this drive! and to my dismay within a week of Super light use the drive was dead - unable to boot or anything -will try a firmware update but i am not very optimistic at this point

Manufacturer Response:

Hello Joseph,
Your feedback on the Black2 drive is appreciated and we thank you for bringing the unexpected concerns to our attention.
If possible, we recommend running a diagnostics on the drive either with the DOS bootable version of our software or by connecting the drive to another system as a secondary drive. We have provided a link to the software download and procedure below.
“How to check an internal drive for defects, problems, corruption, or a power issue”:

Should the drive pass the test and is also recognized on another computer as secondary drive, please run the firmware update on the drive and then write zeros to it to clear out any residual configuration on the drive potentially causing the issue.
“Firmware update for Black2”:
“How to low level format or write zeros (full erase) to a WD hard drive or Solid State drive”:

If the drive returns an error or is not able to be tested, we would like to replace your device for you directly and receive this one back for further testing and analysis. You may contact our Support Team by phone or email below and reference your Newegg review with the first agent you speak to.

4 out of 5 eggs

Pros: All in one package. If you are using a small form factor or laptop this can be the drive for you.

Cons: Unlike Samsung 840 Pro I own the WD Black Dual Drives doesn't have a protective outer shell and more susceptible to ESD which makes it less than ideal for those wanting to switch out between drives. Slower SSD performance, should have reviewed performance ahead of time.

5 out of 5 eggsExcellent as Fusion Drive !

Pros: I just entered the world of Mac by purchasing a Macbook Pro Mid 2012 with 4G of Ram and a 500GB HDD. First order of business was to upgrade both the Ram (to 16GB with Crucial Ram) and upgrade the HDD. I found this drive to be perfect for setting up a "Fusion Drive". The install instructions are lengthy so you need to be patient, but it works like a champ !! My Macbook Pro lists it as a "Fusion Drive". I wonder if WD will come out with one of these drives, but with a 256GB SSD (or larger) instead of the currently integrated 120GB. WD has easy to follow install instructions and the necessary files needed to prepare this drive for compatibility with Mac OS X systems. I did a clean install of Mac OS X 10.10.1 Yosemite instead of cloning the original HDD that came with my Macbook Pro. Now I just have to get familiar with running a Mac instead of Windows, which I've been doing all my life.

Cons: As of this moment (5 days installed) absolutely no issues ! If there are any glitches, issues or problems, I'll certainly update this post, hopefully there won't be !

Other Thoughts: I'm glad that my first entry into the Mac computer world is at a time when upgrades on some of there products are possible. This was one of the primary reasons I stayed away from Macs, even though most Apple/Mac users raved at how great the technology was. The ability to "tinker" with these things is appealing to many Windows users and, while most "die hard" Apple/Mac users claimed this is not necessary for the Apple/Mac products, I'm sure there are plenty that are excited about the fact that they now can.
This product is the only HDD that I could find which can simulate a Fusion Drive for use in a Macbook Pro (at a much cheaper cost), I hope WD launches an updated model with a larger integrated SSD than the 120GB currently part of this WD Black2.

4 out of 5 eggsGreat drive, but watch out!

Pros: Works great in a single drive setup.The SSD is fast and reliable, while the HDD has great storage and highly reliable. However remember its slower cause its a disk drive and disk drives need time to spin up.
Great customer support.

Cons: If your device supports 2 drives. The WD Black² Dual has to be your primary in order for you to use the 1TB HDD.
Does NOT support RAID.
Drive will only function in IDE mode.
Personally these are major cons for my situation.

Other Thoughts: A pro or a con depending on your situation. This is a non standard hybrid drive.

3 Eggs for creativity
1 Egg for reliability
Removed 1 Egg for compatibility.

5 out of 5 eggsWorks great in a Macbook but requires some work

Pros: SSD and large storage in compact package - perfect for a laptop running iTunes. Once the drive was set up the install went smoothly

Cons: Set-up for a Mac is intensive but not hard. Standard HD is a bit slow to start after sleep but that is expected to me when compared to a SSD drive. Requires "Trim" management software in OS X.

Other Thoughts: Takes some significant steps to make this work on my late 2008 Aluminum Macbook as an iTunes server. Installed in a Win7 tower to install software and active drive. Transferred drive to Macbook and used the Mac Drive utility to divide the drive into two partitions - 120GB (SSD size) and 1TB (regular drive). Installed OS X on the SSD and moved the Music folder to the 1TB partition. Also, remember to tweek the OS X settings for a SSD drive and install software to manage drive "Trim"

4 out of 5 eggsGreat Upgrade

Pros: Great form factor size. the ssd side of this is blazing fast. and the hdd side of it is working great now! (see Cons as to why I used that wording).

Cons: when I first started using the hdd side of it for my gaming, I was more than I little frustrated. it would hiccup every 15-20 seconds and act like a network delay. I know its not my network because I wasn't playing anything online. I was close to sending it back, but like a good tech head I started digging a bit online and found out there is a firm ware update. it fixed it perfectly! the fact that I had to do it is the reason I only gave it 4 eggs. and because its my main os drive you can't do a exe file to fix it. you have to boot from a flash drive to fix it. rather time consuming.

Other Thoughts: I had been watching this combo drive for quite some time. and was glad it finally dropped to a reasonable price. glad I bought it! well worth the frustration of the firmware!

2 out of 5 eggsUpdate (Drive freezes)

Pros: So I have had this drive for quite a while now. It is currently in my laptop running Windows 7. In general it works fine but there is a major problem.

Cons: The huge problem is it keeps freezing. I will be using my laptop like I always have been but about once every 3 times my computer is running, it freezes to the point where I need to hold the power button to turn it off.

I have been thinking of going back to my old HDD. In my opinion, it is not worth the current $150.

Other Thoughts: I like the concept and everything but with the last update about 3/4 of a year ago, I do not know if WD is going to keep going with this product.

4 out of 5 eggsGreat buy for your one drive bay laptop

Pros: Pretty fast SSD
1TB of HDD for storing large files.
2.5 inch form factor
Cool design
Easy install (software side)

Cons: 5400RPM HDD
Slow write speed for an SSD, and read speed is also slower than most.

Other Thoughts: This drive is great for a single drive bay laptop. Although I would prefer (and many people have given this drive a ton of flak for this reason) to have a SSD and HDD separate from each other, that is not possible in my laptop. I got this drive from Newegg (which has always been great to me in the past) for an amazing price which was the equivalent of a separate HDD and SSD. I couldn't refuse it. So far I have no complaints!
