About this product
- Product DescriptionComputers use a lot of energy, and the WD20EZRX minimizes your machine's power consumption and carbon footprint. It also boasts a great deal of speed as an energy-efficient drive. This is one of WD's respected Caviar Green drives designed to help reduce computer energy use by up to 40%. If you have multiple computers or are watching those electric bills closely, that is a big savings.Whether you are repairing or building a computer, the Green HDD is a great option for all. This particular 2 TB hard disk is compatible with Windows 7, Windows 8, Windows 10, and Mac OS. Roughly the size of your palm, it measures 5.78 inches long by 4 inches wide. It is also 1.08 inches tall. You'll find that the four-pound piece of hardware is built to be strong and long-lasting. Installing this large capacity drive can be done in a few steps.Just mount these Green drives in a spare 3.5-inch form factor hardware bay on the front of a desktop. You'll need to use four mounting screws either in the sides or bottom to hold it securely. This 2 TB drive uses SATA cables. Provide energy with a SATA power cable or a legacy ATA-4-pin Molex power connector. You can also use your SATA data cable to access the drive.A Dual Stage Actuator on the 2 TB 7200 RPM Western Digital allows for higher precision motion. This means you'll get two times the data performance and increased drive reliability. NoTouch Ramp Load technology also keeps the recording head from touching the disk media. Enjoy increased reliability and reduced head wear and tear on these drives.These drives bring plenty of performance to the table with a hefty 64 MB cache and 7200 RPM rotational speed. The 3.5-inch internal drive is specially tuned to maximize power efficiency and quiet operation. A big power draw with any high-RPM hard drive is the motor that spins the platters. Intellipower on the Western Digital Green stops the platters and parks the heads after 8 seconds of non-use. The WD20EZRX relies on its large cache to handle its spin-up time, seamlessly producing the files you want while conserving energy. You won't sit there waiting for the hard drive to recover must-have files. Plus, the result is a quieter and cooler system that sips less energy. For a break from the sound of your HDD whirring frequently, Caviar Green drives are a solution.The Western Digital WD20EZRX is a good solid choice for a home or work desktop. It can open your files quickly and efficiently. With 2 TB of storage, you'll have plenty of room for all of your media. You can store up to 1,000 hours of movies and video or up to 620,000 photographs. Music lovers can save about 34,000 hours of songs too.

Very poor primary or boot drive, excellent storage drive (read the text)
Disclosure: I bought two of these. Initially I was VERY unhappy. Then I reasearched what I had purchased and changed my mind. Overall, there are three types of data on your computer: (1) the stuff that you need immediate and absolute rapid access to - the OS and the swap space. (2) the applications, and the current project(s)). (3) the stuff that you need later. In my case, 10% of the My Documents directory are the current project. The other 90% of it and all of the offline backups (i.e. the USB external drives) are in the category of stuff you need later. These WDnnEXRX series (where nn are any digits) are NOT what you would use as the boot disk drive in a computer - i.e. the the OS and the swap space. For the OS and swap space you want a solid state disk. For the applications, and the My Documents you want a 7200 (or 10,000) RPM WD "Black" drive (or the Segate, etc. equivalent). These WD "Green" drives are what you want for "the stuff you need later". NOTE: No mattter what the ebay (and other) sellers say this drive is NOT a 7200 RPM drive. It is a VARIABLE speed drive that has a maximum speed of 7200 RPM. While it's being accessed it ramps the speed up to 7200, when it's not being accessed it saves some DC power and ramps the speed down to 5400 for a while, and after a period it actually spins the drive down to a dead stop for maximum power savings. This behavior is controlled by a complex algorithm that you CAN'T override. The WD literature says that the "Green hard drives reduce power consumption by up to 40% and offer best-in-class acoustics and operating temperature". Read that as saying that the algorithm controls the drive power, speed and performance to maximize the "greenness". Translation: It's a low power drive that will have real sluggish response when it's in the max power saving mode. The WD literature also says that the "IntelliPower" algorithm implements "A fine-tuned balance of spin speed, transfer rate and caching algorithms designed to deliver both significant power savings and solid performance". Note that is doesn't mention anything about optimizing the transfer rate. Yes, it does 6 gigabits per second - but only for what is in the 64 MB buffer. Once it has to go outside the buffer it has to spin the drive up (if it's halted), or wait for the platters to come around. Translation: It's a low power, sluggish drive. The WD literature also mentions "IntelliSeek - Calculates optimum seek speeds to lower power consumption, noise, and vibration." Well, "seeking" in a drive involves moving the disk heads. Drives designed for any level of performance move the heads as fast as possible - if you could see through the walls of the disk drive the head carrier would look like it had a incredibly bad case of the muscle twitches. These movements obviously use power and any moving any mass results in vibration. Noise is a given in any device that has moving parts - be it car, a drive spindle or a head carrier. If the "IntelliSeek" algorithm modulates the seek speed to lower the "power consumption, noise and vibration" it's an admission of low performance - another reason to NOT use this drive as a primary drive. Translation: It's a low power, sluggish drive. On the other tentacle, all of the above are GOOD reasons to use these drives in any non-RAID external storage drive housings (USB, etc). They would also be ideal in a solar powered data collection system or any type of battery powered system. Read full review

WD drives are a good value for home media servers and desktop hard drives.
I bought this drive because I was in need of a new 2TB hard drive (at Christmas Time. I always like this type of drive for desktops and home media servers to store my files on. The quality is very good for a desktop drive. Watch out that you don't pay more on a used drive for the price of a new one. Overall a very good value for the dollars. One thing though I would suggest that all used drives have listed on them the powered on days and hours count so that you know what the real life span is on the drive.

I bought them because they are "Green".
I bought two of them because they are "Green". Since I have four internal HD in my Mac Pros, I use one 2TB for an internal Time Machine. I am happy enough with both. I have many WD HDs and they work, except for one WD Black (the fastest one they say) which never worked (yes I tried it in different ways).

Excellent Hard Drive For The Money!!!
My hard drive works very well for the money. I had to format it on another PC, because the Pc I installed it in wouldn't install the Windows installation files. It work out very good and I'm very happy of it's performance.
