Review of the WD Caviar Green 2TB SATA Hard Drive

You could easily argue that a hard drive is the most important component of your computer or storage device, and personally I agree with that. After all, it is the hard drive that stores all of your important data and serves it up to you when you ask for it.

Hard drives come in all shapes and sizes, and recently Western Digital released the worlds first 2TB SATA drive, the Caviar Green 2TB drive, WD20EADS.

Well I certainly couldn’t pass up the opportunity to play around with one of these drives. The drive itself consists of 4 separate 500GB platters – seriously, how do they manage to fit them into the same size that only a year or so ago was 1TB!

The “Green” element of the drive refers to the fact that it has a reduced power consumption of up to 40% compared to standard desktop drives but rather than reel off a lot of features, I will just paste them below from the product description.

Product Features

Reduced power consumption — WD has reduced power consumption by up to 40 percent
compared to standard desktop drives with the combination of WD’s IntelliSeek™, NoTouch™,
and IntelliPower™ technologies.

Helps enable eco-friendly PCs — By using environmentally-conscious PCs with our
WD Caviar Green drives on board, large organizations with many desktop computers can
minimize their carbon footprint and save real money on electricity costs.

Cool and quiet — GreenPower™ technology yields lower operating temperatures for
increased reliability and low acoustics for ultra-quiet PCs and external drives.
Perfect for external drives — External drive manufacturers can eliminate the need for a fan in
a high-capacity product with a WD Caviar Green drive, the coolest and quietest in its class.
IntelliPower™ — A fine-tuned balance of spin speed, transfer rate, and caching algorithms
designed to deliver both significant power savings and solid performance. Additionally,
WD Caviar Green drives consume less current during startup allowing lower peak loads on
systems as they are booted.

IntelliSeek™ — Calculates optimum seek speeds to lower power consumption, noise, and
vibration.

NoTouch™ ramp load technology — The recording head never touches the disk media
ensuring significantly less wear to the recording head and media as well as better drive
protection in transit.

StableTrac™ — The motor shaft is secured at both ends to reduce system-induced vibration
and stabilize platters for accurate tracking during read and write operations. (2 TB model only)
Native Command Queuing (NCQ) — Server feature for performance in random I/O
transaction environments. It aggregates many small random data transfers and allows the disk
to reorder the commands in a sequential order for faster access.

Perpendicular Magnetic Recording (PMR) — Employs PMR technology to achieve even
greater areal density.

Low power spin-up — WD Caviar Green drives consume less current during startup allowing
lower peak loads.

Advanced power technology — Electronic components deliver best-in-class low power
consumption for reduced power requirements and increased reliability.

Thoughts and Conclusions

My first thing when playing with this drive was to put it into my Windows Home Server and use it as part of the storage pool. The size of the drive is great for increasing my available space, and the fact that it uses a lot less power and produces a lot less heat than most other drives would be perfect. But then I decided that it might be even better to use it as the primary drive on my main desktop machine, so that is exactly where I put it, and where it is right now.

It has been running now for a few weeks and I haven’t had a single problem with it. In fact, it really is so quiet that you barely know its there! The speed of the drive is great as well – ok, it is not the fastest hard drive on the planet, but it also doesn’t claim to be. Now don’t get me wrong, it isn’t slow either! In fact, I would be hard pressed to find anything bad to say about the drive (except maybe the price, and even then it wouldn’t be a complaint as much as a quiet grumble).

I can highly recommend this drive to anyone who wants to increase their storage capacity, or even someone who just wants to use a more “eco” friendly drive.

Sorry Western Digital, you are not getting this little beauty back. Any chance of a few more – for research purposes of course 🙂

The WD Caviar Green 2TB SATA Drive retails in the UK for around £180 (including from Amazon)   and around $299.99 in US. Whilst it certainly isn’t cheap, it really isn’t that expensive really considering what you are getting for the price. And like a lot of technology, this is the only “one” on the market right now so expect the price to drop eventually.

  1. NewEgg is quite clever controlling their online system.

    Number of clicks on a specific item combined with stock level

    etc. can change he prices within a natter of hours.

    BTW.

    The 1TB Green WD goes for $79

    http://www.newegg.com/Product/Product.aspx?Item=N

    So if I have a case with few spots for HDs it means 2TB for $160.

    Or two of these get you 3TB for $240

    http://www.newegg.com/Product/Product.aspx?Item=N

    Otherwise (for special occasions) the Green 2TB is a nice touch.
