THE QUICK TAKE: The WD10EARS is a new (shipping 12-2009) version of Western Digital's popular and successful WDxxEADS Caviar Green series of drives. It's a very good drive, but may need more thought than usual about whether it's the right drive for you.

The Caviar Green drives offer low power consumption, low noise and moderate operating temperatures, while still maintaining performace good enough for many applications, such as networked storage. This new WDxxEARS series uses more dense 500GB platters - so a 1TB drive has just two platters, and several drives up to 2TB are available. The new models have 64MB of cache.

ADVANCED FORMAT: There's another change as well. WD is using this series to transition to 4KB sectors on the hard drive; they call it WD Advanced Format technology. The long-term goal is to improve the efficiency of large hard drives, but as a transitional move they still trying to accomodate the 512B sectors that Windows XP uses. So the drive emulates that, using 512B logical sectors. However, they still claim that Advanced Format provides an improvement in burst speeds.

ISSUES WITH XP: While that sounds like all good news, it turns out that many XP users need to use the WD Align software to setup the drive, which can be time consuming and create some potential issues in formatting and partitioning the drive, and in finding tools to do that.

The exception is if you are using a single partition for a clean install - then there is an option to set a jumper on the drive before installing.

I purchased this drive to replace the drive in my Wife's computer that was running out of space. The PC was running Windows 7 and the drive being replaced was a WD3200KS 7200RPM drive.

PC the drive went into: Stock Intel Q6600, Gigabyte GA-EP45-D3SL, 8GB DDR2, and a ATI HD4870.

The Windows install wasn't that old and I didn't really want to mess with getting her all her stuff back so I used a Clonezilla Live CD to clone the old drive to the new one. I then booted straight into Windows 7 off the new drive. Windows asked me to restart so I did and the system was up and running without incident. I then went into the Windows 7 disk manager and extended the partition to fill the whole drive.

Knowing this was an Advanced Format drive but unsure if the alignment would be correct due to the cloning, I downloaded the bootable image for the align utility from the Western Digital site and burned it to a CD. I ran the utility and it indicated that the partition was aligned correctly and there was nothing that needed to be done.

The old drive showed as a 5.4 and the new one as a 5.9 on the Windows Experience Index. I didn't think that was too bad coming from an older 7200 RPM drive to this. I was a little worried it would be slower but that isn't the case. I haven't personally used the PC enough myself to know but my wife says she notices it is a bit faster and things are quicker to load.

This drive for me was a worthwhile upgrade and money well spent to this point. Only time will tell about the reliability as with any drive.

I purchased this hard drive in October 2010. It failed in May 2011, that itself was not enough for 1 star but the fun does not end there. When I tried to create RMA in WD website I got surprising message that warranty on my drive ended few days before I bought it. I contacted them via email to explain that I just bought it few months ago and it was advertised as having 3 year warranty and this is response I got :

"Thank you for contacting Western Digital. I apologize for the inconvenience but we can only accommodate for 1 year of shelf life. The manufacture date of this drive was 20-SEP-2007 and your purchase date was in 2010. Unfortunately, your drive does not qualify for warranty update."

So WD basically told me the warranty starts from the manufacturing date not the purchase date. Very dissapointing attitude.. I contacted Amazon and they agreed to take it back. You may want check the warranty status on WD website if you decide to buy their product anyway. I am personally going to stay away from them in the future.

Avoid these drives like plague as they have high failure rate. I have two of them and one failed in less that 12 months with 750MB data on it after using only for backups.
Luckily the drive was under warranty, but WD requires customer to pay for shipping to replace their defective product. To add insult to injury the replacement was a refurbished drive which I fully expect fail even sooner than the brand new one.

Do not be swayed by the low price of these drives as you will have to buy two and back often. Also save your coins for shipping charges and pray drive fails within warranty period otherway you are left with a heavy paperweight. I also have a failed 160GB version of WD drive.Western Digital Caviar Black 1 TB Desktop Hard Drive (WD1002FAEX)
