Verified Purchase
I was skeptical at first.

But I bought two, and put in a RAID1 mirror config, in a 8-drive raid box with 2 x multilane infiniband interfaces and a RocketRaid card.

The 64MB cache is noticeable, totally. It is not hype. On average, I get 100MB/sec copying across a gigabit network in the LAN from one machine to this RAID volume. In a similar test (using the same source machine, to a volume of 750GB AAKS', I get ~82MB/sec across the wire. Again, the cache is noticeable in my tests.

I am amazed at the quality of this drive.

I recommend these drives to anyone who needs to use a RAID config, and needs capacity, and reliability.

I only use WD, period.

I currently own 46 hard drives, all WD.

The only WD hard drive I ever had fail, was a green 750GB one.

The older AAKS series was phenomenal, and these are the new ones to get!

(I have had drives fail a great deal using other manufacturers)

I'm not normally a fan of SATA drives, I've worked extensively with SAS/SCSI drives for servers/etc for the last 20 years and only used ATA/SATA when required.
Still, I've had some projects come up recently where the only option was SATA and high capacity was required.

After some bad experiences with the WDC Cavier Black 2TB, I gave the RE4 a try. It's been great. I've now had 5 of them running for the last six months and the SMART monitoring reports still show the drives as in almost new condition...no errors, no need for sector changes, no unusual increases of load cycle counts, etc. Performance has also been very good....surprisingly good for a mere 7200rpm device. Not to mention, the drives seem to work nicely in both software and hardware raid. I'll probably end up buying another 5 of them soon.

I'll be very happy if I can keep the failure rate to under 4%/yr....this historically is a good rate for SATA/ATA.

I'm not sure what to think about WDC.....I generally prefer seagate, but the RE4 drives certainly seems to be able to back up its claim as an enterprise SATA drive.

I bought this to replace a Seagate backup drive that lacked enough room for drive images. The WD5003 is quiet and speedy and comes with a 5-year Enterprise warranty. No problems with it at all.

Buyers have been complaining about Amazon's poor bare-drive packaging in many of the reviews I've read. However, this drive was packaged properly in a box of its own made by WD, with plastic end caps suspending the drive over the bottom of the box. This package was put in another box with the rest of the items I ordered and a couple of air pillows. Perhaps Amazon has listened to the well-founded complaints and revised their bare-drive shipping accordingly. Then again, it might only apply to this particular hard drive.

Do not buy this drive from XBRdepot. For starters, this is the cheaper WD1502FYPS RE4-GP drive and the drives they sent me were pulled out of an external enclosure, model WDBAAU0015HBK-NESN which is the WD Elements Desktop. That drive carries a 1-year warranty as opposed to the 5-year warranty these drives should carry by the model number this vendor is trying to sell. CHECK YOUR SERIAL NUMBERS ON WD's WEBSITE AS SOON AS YOU GET THE DRIVES!!! This will ensure you have received the proper drives and allow you to fix the problem before you are stuck with them. Don't be a victim of fraud!

I installed the HDD, initialized it under Win 7/64bit and ran Western Digital's Data LifeGuard (from their website as a free download). Drive passed SMART test and short test. I then ran the extended test twice. Both times, the test aborted due to an excessive number of bad sectors. I returned drive and asked amazon to send a replacement.

The replacement drive was sent with NO protective packaging and their shipping method did NOT meet Western Digital's requirements for shipping hard drives. I posted picture of how drive was shipped. The drive is on its way back. A third drive has been ordered.

I'll update review when I receive and test third drive.

EDIT 27Nov2012: The third drive passed all WD LifeGuard tests, was installed into the new desktop, and has been operating perfectly. This third drive has a "5 star rating".

I ordered 4 (amazon prime fulfilled) and one of the disks appears to be refurbished, not new. It was not packaged in a WDC factory box and when I try to register it with WDC the page says "No Limited Warranty". The other 3 came in an original factory box and I was able to register the 5 year warranty. Whenever you receive a drive you should register the warranty to make sure it is fully covered -- 5 years for RE4s. I own 26 of these drives (12 bought from amazon) and like them. But shame on amazon for pulling a trick like this.

Amazon is sending a replacement and it should arrive very shortly. Assuming it is a new drive I will revise this review and update the rating.

Update: I received a new replacement drive and was able to register the 5 year warranty.

This drives are fast for a SATA II drive. In a 6 drive RAID 6 configuation using a 4805SAS 8CH Sas Raid Ctlr Sgl Pcie 256MB Sas/sata/sataii HD Rohs controller (write-through with battery option) I get 360-380 MB/seconds R/W as measured with the ATTO Bench 32 program.

Ordered two of these drives from Aeon Micro that were heavily used and had no warranty from Western Digital. Listed as New with 5 years warranty. The S.M.A.R.T. table on the drives, outside stickers and Western Digital warranty checker state:

hours 1394 s/n WCAW32746976 start/stop count 20 manufactured 07 AUG 2011 warranty "Out of Region"
hours 1393 s/n WCAW32743942 start/stop count 11 manufactured 07 AUG 2011 warranty "Out of Region"

You can use a free program, Speccy created by Piriform, to see the S.M.A.R.T. data on any drive connected to your PC using Windows. With the low start stop count these were probably from servers or some other devices that are on for long periods.

The drives looked new on the outside so had been cleaned and were in sealed antistatic bags that were different from the ones new drives come in from Western Digital. Clearly having been made to look new.

They offered to replace them with new drives with a different model number but I did not do that. I took a full refund. They did pay to ship them back and refunded the entire original amount but I wasted more than two hours of time unpacking, checking the drives, emailing back and forth with Aeon, repacking, labeling and taking them to the shipping drop-off.

These are USED Drives!!! The listing is marked as new, they come packaged "OEM" style but the package seems home made and not factory. The contacts seem discolored just like when they have been exposed to the air. I bought 2 drives and after doubting their "NEW" condition I ran a SMART check on them 1 drive has about 6800 hours that like 285 days of non stop up time and the other is 1000 hours!!

Well, if you think you are buying cheap WD RE4 HDD, you are wrong, just like me.

The model # is MB2000EAZNL. When I googled it, it's HP HDD, not WD. This doesn't bother me at all.

What really bothers me is the power on time is 22,784 hours (31 months 19 days 8 hours).

I thought I was buying a new HDD, but I guess the seller is playing us.

As mentioned in other reviews, if you buy this hard drive be sure to verify that the advertised 5 year warranty is valid. The one I received was not packed like other new Western Digital drives I have purchased, so I immediately suspected it being not as represented. The Western Digital website correctly identified the drive from the serial number and listed the complete specification. However, they indicated NO warranty. I immediately repackaged it and and returning it.
