  • A reliable beast for creatives
Capacity: 8TB
I've been using this hard drive for several weeks now, and it has truly exceeded my expectations. If you work with large files like video projects, renders, or game libraries, this hard drive is an excellent investment. Loading and transfer times are fast for an HDD, and the 256MB cache makes a huge difference when moving large folders. It's a SATA drive, so don't expect the speed of an SSD, but within its category, it performs very well. I have it mounted in a tower for video editing and storing old projects, and so far, I've had zero annoying noises or overheating. It stays cool and stable. Something to keep in mind: this model is more expensive than a regular hard drive, but it's clearly built to last. If your workflow is demanding or you want a robust drive for your game or media library, the price is justifiable. ... show more

  • Reliable drives
Capacity: 2TB
This review is for the 2 TB black hard drive. I have owned several different brands of hard drives and several different versions of WD’s hard drives over the years, including the greens, reds and purples. I have only have had one failure in that time, which happened to be worked hard, operating on a security camera server for a few years before failing. This is my first black as I wanted a reliable drive for backing up my desktop. These hard drives have a great 5-year warranty, which is one of the big reasons, I purchased this. I connected this drive to my Windows 10 computer with no issues. It took less than a minute to get setup and going. It was pre-formatted, so it was quick to a drive letter and get going. File transfer speeds are fairly speedy for a large size drive. I do think the drives are a bit pricey, but have come down in price over the last couple years. I currently have three of the black drives, this 2TB, a 6 and a 8TB....all have been reliable so far. Overall, other than being slightly pricey, these are great hard drives with good speeds and good warranty that I expect to be reliable over the long term. 4.5 stars ... show more

  • This is a "better" quality, very fast Western Digital drive that works with eSata or USB 3.0 in an external docking station.
Capacity: 2TB
Western Digital hard drives are my choice when I pick a new hard drive. I used to live near their California HQ and was a former head of a large PC user group and learned WD has good quality. This drive is more expensive than others because i researched which one was good for handling heavy graphic read and write's when using video editing software and the file was on an external drive. This is a SATA drive and runs the faster 7200 RPM with a large cache. You have to either install this an internal drive, or buy an external drive case for this, with cables, etc. This is a do it yourself product and not for novice users. This drive is NOT a consumer product. You have to go to the website to get the instructions on how to format this drive, etc. That is what they mean by Bulk/OEM labels - it lacks any extras included with consumer hard drives in a box. You have to order the cables you need, and download the configuration software from the WD website, which is fairly easy to do. If you don't want to configure a drive like this, find a consumer external drive with the CD, cable, etc. and buy it instead. You need to know if your PC will handle large partitions, ie. 2 TB, or you have to format it with several partitions due to older operating systems. I did not buy a separate external drive box, but bought an Anker external open case with power supply and capability to connect to both USB 3.0 AND eSata connections. I did that because using the eSata port on my old laptop was much faster than 2.0 USB. But, I can move the box and drive to my desktop which has a USB 3.0 add in card. Both eSata and USB 3.0 are much faster transfer speeds than USB 2.0 and this drive can handle it. I have included pictures of the drive working fine in the Anker case so you can see both in use. Note: Hard drives have standard connections to the case or internal slot for power and data transfer. The ability to provide USB 3.0 or eSata connections is built into the case, not the hard drive. Both USB 2.0 and eSata require special cables, so don't forget to get them if you do this. In my case, since I used the external "open" Anker docking station, I didn't need cables. I just slid the drive into the docking slot and the connection for data and power was made. The Anker unit also has an on off switch. Of course, if you use this drive internally in your system, that is a different process and involves other tasks if you make it your primary drive with an operating system. I did not do that, so mine is used primarily for a video data file drive and has not been setup with booting capability. You can't go wrong with Western Digital. (Unless they sell out to someone,then watch what changes in quality). You can get this drive in 1 TB, 2 TB or 3 TB versions. I got the 2 TB version and it cost about 30% more than WD drives with lower speeds and features. ... show more
