While testing the drives we used a KINGWIN KF-1000-BK 3.5" Internal hot swap rack attached to one of the six ASUS P5Q-E onboard 3Gb/s SATA II ports. A hot swap utility was used that allowed us to spin down each drive and swap it out without rebooting.

HD Tach
 HD Tach v3.0.1.0

We began our testing with Simpli Software's HD Tach, which is described on the company's web site as such: "HD Tach is a low level hardware benchmark for random access read/write storage devices such as hard drives, removable drives (ZIP/JAZZ), flash devices, and RAID arrays. HD Tach uses custom device drivers and other low level Windows interfaces to bypass as many layers of software as possible and get as close to the physical performance of the device possible."





The Western Digital Green Power 2 TB delivers impressive results in HD Tach. The read/write, random access, and burst speeds are all great for a consumer hard drive, especially one that employs "Green Technology". It even turns in the best write results among all the drives except for the high performance WD Velociraptor.

Awesome, finally some reviews of this bad boy!! Haven't even read it yet but I NEED 4 of them so I am praying reviews are good and price starts coming down. $299 is way to expensive for a 2 TB drive when 1.5TB are around $120.

Thanks!

 

Any possible plans to review it in a NAS or a RAID array in the future?

I wondered how drives with variable spindle speeds would perform in a RAID config and then noticed that one of the features of the Caviar GP's enterprise sibling - the RE2 is firmware with improved RAID functionality. There is not a 2GB RE2 GP out yet but it would be interesting to see in a heads up raid comparison.

Not at the moment. I'm sure they'll be fine though...the 1TB version of the drive (two fewer platters) works fine in a 4-way RAID 5 configuration in my NAS box.

...As long as your NAS device supports the drive that is...

Good point, I know it currently supports 1.5 TB drives but might need a future firmware update for 2TB.

a good firmware like that have a good price indeed

Looks like it performs better than the 1TB version. I guess the higher density helps with that.

from the article:

"The Western Digital Green Power Caviar 2TB drive features 4 - 500GB platters rotating at a variable speed that is determined by the transfer rate required at any given time. Due to this variable spindle speed Western Digital has not published any rotational speed specifics. "

I cannot believe "journalists" are STILL making this mistake

NONE of the GP drive VARY their spin speed - this would be INCREDIBLY difficult to achieve!!!  Each drive has a fixed speed - so far they are ALL very very close to 5400rpm (its easy to measure the spin speed with an oscilliscope and "listen" to the hum of the drive) - and even under very very heavy load - the spin speeds dont change, at all.

Even another hot hardware article says:

" We know that they are likely spinning at a speed between 5400 and 7200 RPM and that each GreenPower model may use a different, invariable RPM."

docchris, you are correct and the article has been updated to reflect the correct information.

Hummm, interesting.  My NAS already has four WD 1TB Green Power Drives though (Not to mention three USB 1TB External drives plugged into it).  I would end up buying a second NAS if I picked up four of these.  I think I'll hold off until I reach 50% full storage on my current NAS and server before I upgrade again though.  That'll be another... 2.5~3TB of data I think.  I'll check when I get home from work.

Overall though, this looks like a nice little upgrade.
