I recently found myself spending so much time juggling how I was storing my data in order to get it to fit on a combination of a 2 TB and a 1.5 TB external hard drive, that I thought it might be worthwhile to revisit getting a 3 TB external drive for backup. I decided against getting a 3 TB drive when they first came out, in part due to AnandTech’s unfavorable review of the only 3 TB drive on the market at the time, Seagate’s GoFlex Desk 3TB. The big turn offs for me were the poorly designed enclosure resulting in very high temperatures, high $/GB ratio and a host of compatibility issues. Since that time, both Western Digital and Hitachi have gotten in on the game as well with 3 TB offerings of their own. I opted for the My Book Essential 3TB, since it seemed to have the best designed enclosure of the bunch, offered the cheapest $/GB ratio of any of the 3 TB drives on the market at $165 via Newegg and gave me a chance to try out my USB 3.0 port on my Asus P6X58D motherboard.
Installation of this drive was decidedly NOT a breeze. I ended up having to update my motherboard’s bios, USB 3.0 controller sub-firmware and USB 3.0 drivers just to get the drive to be recognized and then had to install and then update Western Digital’s included Smartware software in order to update the drive’s firmware in order to get it working properly. I wouldn’t recommend this to clients as a “just plug it in to gain 3 TB of storage” device, but once I got it working it has behaved like any other external hard disk drive and has stayed comfortably cool via strictly passive ventilation and worked reliably through multi Terabyte initial data copying and subsequent daily backups.
Western Digital doesn’t exactly go out of their way to advertise it, but this drive spins at something below 6000 RPM (hence the assorted eco-branding). Even with the fast USB 3.0 interface, this drive performs considerably below any 1.5 or 2 TB drive I’ve owned, even with those drives being in USB 2.0 enclosures. This drive is decidedly for bulk data storage purposes only.
One other thing Western Digital doesn’t advertise is that the drive used in the enclosure is the same WD30EZRS series drive which they sell for ~$35 MORE as a bare OEM drive sans enclosure. Popping the drive out of its enclosure is relatively straightforward, although you are likely to pop a couple plastic clips in the process, voiding your warranty. Still, if you are looking for a 3TB internal drive on the cheap and don’t mind potentially voiding your warranty coverage, this is about as cheap as you can get one.
I ended up picking up a second unit to use as an internal drive. I kept it in its enclosure long enough to update it to the most recent drive firmware and then popped it open. I am keeping the enclosure in case I ever need to apply another firmware update. It has functioned like any other non-boot drive in my system, save for that the performance characteristics are such that if you have more than a few apps contending for I/O attention from the drive, throughput drops enough that HD video streams start breaking up. This can be problematic if you are trying to watch a movie and a backup job starts in the background, for instance. To reiterate, this drive whether used externally or internally should be used for bulk data storage only.
