This isn't actually mentioned anywhere, but these disks spin at ~5400rpm.

These are great for storing large amounts of data, but I wouldn't use them as my main hard drive.

Nice price. Normally I put a lot of faith into WD drives.

But... I dunno. While one should always take reviews with a grain of salt, there's a lot of reviews reporting bad drives. I'm a little wary of these...

If you're just storing movies or other things that are easily replaced (entire Steam games collection?) and you're okay with them being a little slower, then sure. But I wouldn't trust them for more critical data without a frequent backup plan.

Warning: These drives are not for use in servers or in RAID arrays of any kind.
They intentionally lack a feature variously called "TLER" (Google it). Without it, any internal data error that happens, and they do happen, will often cause the drive to drop off the RAID array.
The reason is because the hard drive will spend seconds, minutes, or even hours trying to make sure it gets the right data from the damaged part of the platter. It won't respond to the RAID controller's polite requests during this time, so the RAID controller will assume the drive has died.

This is all in an attempt to get people to buy their overpriced "RE" series drives, which are physically the same as the consumer drives. Their firmware merely has a shorter timer set for error recovery, all for only an 80% mark-up.

I can't find it for $99.... What's the deal?

oh nevermind- I found the code!

bought 3, 2 with errors within half yr.

I've purchased a couple of these, the 1TB not 2. One died within a few months, I'm still using the other one, but only for storing movies, etc... I'm starting to get errors on that drive now as well. I wouldn't use this as a primary drive. I got them strictly for the price, but you get what you pay for.

@charlesburns: Check out the WDIDLE and WDTLER utilities. Both can make these green drives work beautifully in raid arrays. It should also be noted that most software raid, including linux MD and windows software raid, are able to handle the drive not responding for a short period of time, and typically only drop the drive it it reports lots of I/O errors.

I have 12 of their predecessor, the WD20EARS, in a raid6 array. After a year of heavy use only one has a few bad sectors, and Western Digital's RMA process was quick and painless. Their online drive registration program makes keeping track of warranties easy and RMA consists of clicking a button, explaining your problem, and getting a new drive.

When Newegg say you'll get a "Bare Drive" they really mean it! The hard drive I received was sitting on the bottom of a cardboard box, with a little obligatory padding on TOP to keep it from shuffling around. If the box was dropped or thrown anytime during shipment, there would be exactly 1/8 inch of plain fiberboard box protecting the drive.
Would you install this in your computer? Not me, I sent it back.

While these drives are not recommended for RAID (an extra hundred bucks will get you a few twiddled bits in the firmware), it doesn't stop people from using them. I bought two WD20EARS (previous revision of this model) 18 months ago for use in a NAS device and have not had any problems. They were $90 back then so this is a good deal.

On the flip side, I don't access the device all that often so it is turned off for days or weeks at a time. Also, I ran the WDIDLE3 utility on them to disable the power saving feature where it parks the drive heads every 8 seconds; allegedly this increases the lifetime of the drive and also prevents delays when accessing content when the heads are parked. Not sure if this is supported on this newer model, though.

Speed was a non-issue for me since I'm accessing them exclusively over a 100Mbit network. For boot drives or gigabit networks faster drives are probably preferable. For my use case they are fine and I would buy them again.

Worked well for about 8 months, then just had one of these fail on me a few days ago during a data transfer. Sector 0 corruption - disk became completely inaccessible, though still visible in disk management. Cannot initialize, no success recovering data via software (testdisk, etc). Also not the fastest drive out there, though it ran decently. Wouldn't buy again.

I have one of these drives filled to the brim and it functions flawlessly. The nice thing I've found with the "Green" drives is that when they're not in use, the drive spins down and the heads are locked, making it power friendly & increasing the life of the drive. It only takes about 3-5 seconds to "wake up" and I have no problem streaming video off it over the network (wired and wirelessly). It is excellent for mass storage as a secondary drive.

Just ordered another! :)

For reliability, stick with WD's black series. Also 5600 really doesnt matter if they are adding more plates for the higher storage, not making the plates larger.

I won't use a Western Digital hard drive. Too many problems. I like seagate.......

contrary to many other comments here, I thoroughly enjoy every one of my WD HDD's!

For the record, they're nearly all "desktop" models(3.5" AC powered USB 2.0[all mine] drives in external enclosures) and 1 lonely "portable" type(2.5"[aka laptop] USB[again mine is only 2.0] powered drive in an external enclosure). To date, the only problem I've encountered with any of them was/is solely due to gross stupidity on my part, the drive itself cannot be blamed(I half-awake made the mistake of reversing my laptop & HDD power cables-a mistake I'm unlikely to make again)

Beyond that, I will grant that it is good to know what the specs mean when buying any HDD and suggest taking the time to learn before complaining things don't work like you want them to when it lacks the capabilities to do so, and yes, on occasion the 5400 speeds are "laggy" or inadequate to meet your needs, but often times 5400 is just fine & you should test the performance of your computer hardware before blaming the drive.
