The Barracuda LP (short for “low power”) is Seagate’s latest desktop hard drive. While all other Barracuda 7200 drives rotate at 7,200 RPM, the Barracuda LP stays at 5,900 RPM to help reduce power consumption. This is pretty unique, as the next typical speed would have been 5,400 RPM. Seagate wanted to optimize its low-power drive for performance, and the results speak for themselves. The drive pulls 3.8 to 4.2 W idle power, depending on the capacity—a good result considering the high throughput of almost 118 MB/s for the 2 TB and 1 TB models. The 500 GB version is limited to 113 MB/s. The 1.5 TB drive reaches its limit at only 106 MB/s. Still, the other low power drives are in the same performance range.
The Barracuda LPs show better I/O performance than Samsung’s EcoGreen F2, but both contenders have to make room for WD’s new RE4 2 TB drive, which delivers considerably more I/O operations per second than all of its competition, despite its lower 5,400 RPM spindle speed. Seagate’s PCMark Vantage HDD benchmark results are above average but still trailing the WD RAID Edition 4 in several metrics. Needless to say, we weren’t surprised to see the LP lose out against the clearly-faster Seagate Barracuda 7200.12.
Although Seagate’s Barracuda LP family couldn’t score clear wins in power consumption tests, its 1 TB and 2 TB models achieve the best performance per watt in their class at maximum sequential read speeds. However, the results are entirely different for workstation I/O performance per watt, where others dominate.
Seagate did a great job in catching up with Samsung and WD, as it beats Samsung’s performance and matches WD’s efficiency. The Barracuda LP is solid and efficient, but at this level it is hard to be noticeably better.

Western Digital Caviar Green WD20EADS (2 TB)
This is it: the world’s first 2 TB or 2,000 GB hard drive. It is not a high-performance 7,200 RPM drive, but a 5,400 RPM energy-efficient drive, according to Western Digital’s specifications for the Caviar Green WD20EADS. You may still remember our...

New Desktop Hard Drives: Speed Or Capacity?
Western Digital’s Caviar Green is the first hard drive to offer an impressive 2 TB of capacity. Seagate has also introduced a new drive, the Barracuda 7200.12, but its capacity only spans up to 1 TB. Samsung recently launched its Spinpoint F2 EcoGreen...

Conclusion
Western Digital was the first vendor to release a 2 TB hard drive. The Caviar Green WD20EADS is the best solution if you need maximum capacity as well as maximum capacity per Watt. Due to its more complex structure--it is based on four rotating...
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.
