Power Efficiency (Performance per Watt)

If you divide the streaming read performance by the required power at this workload, you’ll receive these efficiency numbers. Since the performance difference between the drives is less significant than the power consumption variance between the fastest and the slowest drives, power consumption has more impact on the results of the 5,x00 RPM drives.

The same applies to the workstation I/O efficiency test. Keep in mind that the WD RE4 and the 7,200 RPM drives are much faster than the other drives, but they clearly require more power at this workload.
Surface Temperature

No surprises here. More platters translate into higher surface temperature. Rotation speed appears to be of secondary interest.

Drive Noise

More platters again translate into negative results. For this reason, the 2 TB drives with four platters make the most noise, although the subjective difference is smaller than what the charts might suggest.

Definitely evolutionary changes, not revolutionary, but that's what was expected with these drives. A good step in the right direction, nonetheless. I just purchased two of the Samsung Ecogreen 1.5TB drives. They are fantastic drives at a fantastic price. This is great for people that want to backup their entire HD (and SD) movie collection. Thanks for the information, Tom's.
i would still go with the seagate barracuda 7200.12 =D
Woah, Déjà vu! I clicked "next" and got a "Guru Meditation: XID: 275861695" error!
are you guys running on Amiga OS? Or are you just Amiga Fanboys?
Good article up until the Guru decided I wasn't worthy ;-)
Should have thrown in a caviar black and a caviar green for comparison
Doh!... hide the above remark.... I should look at the charts first.
Amazing the performance they're getting out of these slower spindle speed hard drives
wait.... 1tb on a single platter? AMAZING
Are we still on this green thing? Seagate 7200.12 FTW, also Hitachi.. didn't see that one coming. Warranty is important to me because I demand 24/7 on for at least 3 years.
It's about time to step up the RAID array from WD RE2's, tough competition.
Seagate LP performance is impressive but I'm going to have to stick with WD due to Seagate's recent track record.
I'd rather you stick to testing comparable sized drives honestly. I don't care if the 1TB drive is faster, if I have to have a 2TB. Which is what I'm looking for next.
Its too bad you couldn't include the new enterprise class 2TB drive from Hitachi, the Ultrastar A7K2000, that rotates at 7,200 rpm. I assume it would have kicked most of these other drives butts.
I'm also left wondering where the long-ago announced Seagate Constellation ES 2TB 7,200 rpm drive is. With the laptop form factor hitting 1TB recently, I'm starting to wonder if these guys have taken their eye off the 3.5 inch space. Which might be a mistake right now given they're going to get their asses eaten by SSDs in the laptop arena any minute now, and the big 3.5 inch drives might be one of the few areas they're actually safe for a while.
I bought 4 Seagate 2TB drives and the retail package states: 5 year warranty.

See under Overview - Key Features and Benefits.
There is something wrong with the dBA readings for EcoGreen F2 1000GB. Can't be higher on idle.
[citation]we wonder why anyone would still buy the Deskstar if others deliver the same performance at reduced power consumption[/citation]
Not saying I would personally buy the Hitachi, but I also wouldn't buy a drive just because it's a low power model. I'm usually looking for quiet operation, read performance, and low temps. I'm all for making useful contributions to use less resources in life but 3 watts an hour is nothing, I'd never even notice the $0.25 change in my monthly bill. I could save more by not OC'ing my quad which is doing me no good sitting here surfing.
In a laptop low power drives are great, but my desktop doesn't run on batteries.
The graphs of IOPs per queue depth for different load types are surely missing... Not the same for irrelevant PCMark desktop benchies, which are filling a long useless page.
I just bought 1 myself from mwave.com.au @ $299.99 and it works perfectly =)

Bought one what?
I bought the Seagate 2TB one
"High-Capacity Business hard drives" - but only one with business warranty!
So all other are consumer class!
I ended up getting the 1.5 TB 7200 rpm Seagate. It has been amazing. I posted my experience here:http://ellipz.com/?cat=5
I also have the Samsung F1 and the WD Green 1 TB drives. All three have been great.
3 watts per hour might not be much per drive, but if you're running a large SAN with 100s of drives, it quickly adds up to a respectable saving.
