Summary: Hard drives have gotten bigger faster than their sustained read/write speed has increased. At its average write speed it will take about 12 straight hours to fill this drive - typically longer with a lot of small files or a slower external interface. Also, you really need another offline 4TB backup space to which it can be rsync'd periodically to feel safe with this much data on one drive.
Pros: Fast transfer rate for a HDD, low power consumption, 8GB hybrid cache to reduce seeks, large capacity. Makes a solid single-drive online data store.
Cons: lots of data in one place! An even larger cache is always welcome.
Excerpt: The SSD/HDD combo seems, thus far, to be a great bang for buck option. Although getting it to work with windows with the 4TB was a hassle, but it has paid off. I am running this hdd as my main drive and I can report power on until desktop takes a consistent 20 seconds apposed to minutes. My current virus scanner seems to negate some of the speed once running, but that's a given.
Excerpt: Our iMac was getting really slow. I didn't want to invest in a full SSD drive for a 6 year old computer. So after doing a lot of research, I decided on this drive. It's definitely brought our iMac back to life! There's a slight delay (3-5 seconds) when you first "wake" the computer up for the hard drive to get up to speed but after that, it's smokin'. And now we have gobs of space to put all of our iPhone pics and videos!
Summary: I must have ordered the OEM version because all that I received was the disk drive itself. There were no instructions, cables, software, etc. That said, it was easy to install and get up and running. I had no problems at all. Benchmarking its performance is inconsistent because of the nature of hybrid drives, but it seems to perform very well. It is clearly faster than my old drive (which was a 2TB Samsung drive).
Pros: Boot time seems noticeably faster, good price.
Cons: Besides the fact that you have to specially partition this on windows to have it recognize it as 4tb and not 2tb, the noise that the hard drive makes is VERY annoying. Started up after a day or so of usage, I know most drives make ticking noises as the spindle moves, but this drive is extra noticeable and irritating. If something else in your build is making noise to cover it up, aka fans whatnot then it might not be a problem but my case has 4 fans total and on max s...
Nice Upgrade!! Inexpensive speed booster for Photoshop.

Summary: This was purchased to replace a 2TB Barracuda XT, I did a fresh install of everything not a transfer from my old hard drive. I noticed a nice improvement on the boot up time, and after a few days it keeps getting faster, being a wedding photographer I find myself sitting at my computer editing for hours and I've noticed a huge improvement in Adobe Bridge and Photoshop speeds, I'm not a hardcore computer guy so no serious tech talk on specs or speed measurements, it's...
Summary: If you are looking for a fast, high capacity, low cost and cool to the touch drive, this is the drive you want. Unfortunately, I got a humvee drive where the motor emits a constant low level noise between the sound of a hum and a vee, so I am calling this a humvee drive!! I can't stand the humvee noise after a few minutes of being 5 feet away from the enclosed and internally sound padded desktop case.
Cons: Drive motor below expectation, emits a sound between a hum and a vee noise
Summary: I bought two of these, one to serve as a backup drive (and later to be allocated to a new PC). The only issue is that my external drive enclosure only supports 3TB, not 4TB. Purely my fault for not researching, but for some this could be a con to purchasing this size drive. If you plan to use this drive (or any other 4TB drive, make sure you verify your enclosure supports 4tb+). Most as of this writing have a 3TB cap.
Pros: Very fast reads due to 8GB SSD hybrid. I installed this on my old iMac Mid 2007 and everything is considerably faster. Boot times went from 1:43 to 0:33 on a fresh install of Mavericks. Writes are still about the same as any hard drive, but on par with other current generation hard drives.
Summary: I got this to complement my SSD system drive. I moved all the program data files and MyDocuments to this drive plus all the normal data files I use. Most file it would read in normal use are within the limit of the flash memory so I should see some improvement over a normal HD.
Pros: Works - that is always good for a hard drive. Packing was pretty good but I am sure the delivery company can overcome any packing. Haven't exhaustively tested it yet but HD Tune Pro reports 3 to 4 times as fast as 4 TB drive depending on transfer size and it maintained transfer rates of over 150 MB/sec for all transfer sizes over 1 MB.
