Seagate Barracuda Hard Drives

The Power of One

Barracuda hard drives from Seagate give you with the Power of One. One terabyte per disc technology. One drive platform for every capacity need and every desktop storage application. One hard drive qualification effort. One hard drive platform to choose from. One hard drive with trusted performance, reliability, and simplicity to deliver the lowest total cost of ownership.

You no longer need to choose between low power drives, mainstream drives, or performance drives. One hard drive with 7200RPM performance and capacity points from 250GB to 3TB makes it easier than ever to choose the right drive for any need.

The Size and Performance You Want
The Size and Performance You Want

You get more bang for your buck with 1TB per disc technology. Increasing the capacity per disc means the highest capacity drives like 1TB, 2TB and 3TB become more affordable, needing fewer discs to meet your capacity needs.

Your drive is up to 45% faster than the last generation thanks to Seagate OptiCache technology. OptiCache technology combines the latest advances in hard drive microprocessors, DRAM, and proprietary caching algorithms resulting in great performance improvements for you.

No-Hassle Transition to 4K Technology

Product Description

By now the world knows that Seagate Barracuda 7200 drives, from the world's premier storage provider, deliver years of reliable service and high performance. The ideal choice for workstations, desktop RAID, gaming PCs, high-end PCs, mainstream PCs and USB/FireWire/eSATA external storage. After years of pioneering research at Seagate, perpendicular recording is now a proven technology. It increases capacity and dependability by storing data vertically, rather than horizontally. And vertically stored data bits mean increased data density which means higher performance to increase productivity. This drive delivers excellent power savings without sacrificing drive or system performance, giving customers the ability to manufacture PC systems and external storage systems that meet energy savings requirements. Seagate hard drives have long been produced with the environment in mind, and not just with low power consumption. With Seagate and the Barracuda drive, our customers can have the best of both worlds, top hard-drive performance and the satisfaction of knowing they are using a high-capacity drive with a very small eco-footprint.

Size Name:2TB
ok, so this drive is listed as the "Seagate ST2000DM001" and guess what, other than that it sports 2 Terabytes, it tells you nothing whatever about what drive you'll end up with, because Seagate has chosen to obscure and omit relevant Data between different builds, with vastly different performance.

The short advice: Only purchase the WxExxxxx version of this model. This was made in Wuxi, China and uses 2 platters and 4 heads.
This performs 30% better than the version with 3 platters, which has a WxFxxxxx or similar designation.

You'll need to contact the seller and ask them to check the code on the drive. If they can't verify, don't buy it, better to get a drive from Western Digital, where its not a surprise game of whats in the box.

S - SU - Suzhou China
W - WU - Wuxi China
Z - TK - Korat Thailand

F = 3 platters with either 5 or 6 heads, while E = 2 platters.

Weight info received in a comment here, suggests that the 'good' 2-platter drive weighs 534 grams, while the 'bad' 3-platter drive weighs 624 grams.

Seagate used to embed the information about their drives in the model number, but now they obscured it, so they can pawn off whatever they want. Send a WxE model to Publications who test drives, and then ship the crappy WxF model to unsuspecting customers who may never realize they're not getting what they thought they were buying. This should really be illegal.

.

Note 1: This was written for the 2TB drive. It turns out Amazon also shows this review for 3TB drives. This info does not apply to 3TB drives, the 3TB drives always have 3 1TB platters.

Note 2: comparison test results here[...]

Note 3: A relevant post on Seagate's forum stating that these Barracuda have been crippled through redesign [...]

Note 4: Someone commented that Seagate removed any reference to the 2 platter version of this drive in the manual (something which is usually only read after the purchase)

Note 5: Someone explained that Seagate made this change due to the flooding of their plant in Thailand. This is not quite correct since chinese 2 platter 2TB drives are also in circulation.

Seagate's real reason for the change is being able to use lower bin or older tech platters that can only hold ~670 GB, so they use 3 platters. This is a fine business decision, but an honest company would give it a new Model number/name, as its a different product with lower speeds, lower reliability and higher weight.

But why be honest, if you can cheat and make a few dollars extra per drive, by selling it under the same name as the better drive, which has been reviewed extensively and lauded for its higher speeds?

5.0 out of 5 stars 3TB for Synology NAS January 17, 2012
Size Name:3TB
This is one of the select few 3TB drives approved by Synology for use in a variety of their NAS devices, so I put 4 of these in a DS411 in SHR with one disk redundancy (basically RAID 5). While anyone will tell you enterprise hard drives are better in RAID 5 or 6 configurations - and they are right, for the most part - it's hard to deny the big price difference in going enterprise: 3TB enterprise drives are well over $550 right now due to the recent Thailand flood and it may be some time before that price drops significantly. While these drives weren't as cheap as the 3TB WD Caviar Green varieties, I will NEVER put Caviar Greens in a RAID 5 again, so the ST3000DM001 quickly rose to the top of my admittedly short list.

I think it's important to point out that IntelliPower (WD) and CoolSpin (Hitachi) technologies are not really ideal for any kind of RAID array using parity. WD Caviar Green drives, especially, are known to sometimes not power up when needed, ultimately resulting in them getting dropped from the RAID array. A good NAS like the DS411 will put the drives into hibernation after 10 minutes of no activity, so you don't really need the benefit of "eco-friendly" drives in this kind of RAID anyways. Plus, with 7200RPM you will get speed improvements, so it's a no brainer to pick a drive like this over those.

That said, of course these do not have TLER, RAFF and other advantages of enterprise-class drives. So you run the risk of more errors, RAID rebuilds and potential failures by choosing a consumer drive like this. But even though the risk is greater, it's not really worth the extra money to go to 3TB enterprise-class, so I feel this is a good compromise of risk vs. value.

5.0 out of 5 stars So far, so good. April 17, 2012
Size Name:2TB|Amazon Verified Purchase
I've dealt almost exclusively with WD for the last 10 years....I had a string of bad luck with Seagate before that, and had sworn off of them. Well, times have changed, and I'm willing to see if Seagate has improved over the years. Post-flood WD seems to be sticking to the absurd prices after other makers are slowly going back down to reasonable prices. And I have to say price played a BIG part in these recent purchases...I REFUSE to pay more for a WD GREEN drive than I did for a Black drive twice the size a year ago...I just refuse.
In a non-raid environment, this 2TB drive seems to be snappy, worked out of the box, and has had no errors...so far so good. Just ordered 2 of the 3TB variety on the strength of this one.

I've been seeing A LOT of neg reviews lately for ALL manufactures in ALL price ranges, it's my belief that the many DOAs have more to do with how the drives are handled in transit, than quality control. I've SEEN the way carriers toss the packages around to get to others, and have even seen them STAND on packages....no bubble wrap is going to compensate for that kind of abuse. Still other complaints I've seen have more to do with ignorance than anything...who in their right mind expects to drop a 2TB-3TB drive in a 10 year old machine and expect it to work out of the box, without using the manufactureres tool? Or expects lightning speeds when a SATA 6GB drive is plugged into a SATA 1.5GB port? And if I read one more review where a clueless person can't understand why a 3 TB reports as less than 3TB in Windows...I'll scream!

I think it stinks that warrantys have been cut, and there is still the question in my mind if post-flood drives are being rushed out to meet demand before factorys are up-to-snuff, or if all that fresh new equipment means a better product....guess we'll see.
From a one week perspective, I have no complaints with this drive. In the weeks to come, if I DO....I'll let ya know.
