Seagate Barracuda Conclusion

IMPORTANT: Although the rating and final score mentioned in this conclusion are made to be as objective as possible, please be advised that every author perceives these factors differently at various points in time. While we each do our best to ensure that all aspects of the product are considered, there are often times unforeseen market conditions and manufacturer changes which occur after publication that could render our rating obsolete. Please do not base any purchase solely on our conclusion, as it represents our product rating specifically for the product tested which may differ from future versions. Benchmark Reviews begins our conclusion with a short summary for each of the areas that we rate.

Beginning with performance, the new Seagate Barracuda ST3000DM001 3-platter hard drive has proven itself worthwhile. In all file transfer tests, three disc platters usually outperformed five. However, when it comes to operational I/O performance, the opposite was true and the older Seagate Barracuda XT outperformed by a small margin. Using PCMark Vantage as a real-world performance benchmark, the new Seagate Barracuda ST3000DM001 excelled at video editing with Windows Movie Maker and Windows Media Center. Overall, the new Seagate Barracuda ST3000DM001 proved itself to be a solid replacement for the older Seagate Barracuda XT ST33000651AS series.

Previously the Barracuda XT touted a five-year warranty, which helped position the series ahead of most other storage products. The new Barracuda ST3000DM001 arrives with a much shorter two-year warranty, although the low operating temperature and power saving rotational shut-down features may make a long-term warranty moot. Since spinning mechanical storage technology is so mature, especially from a company like Seagate, there are no issues with the Barracuda in terms of compatibility or firmware functionality... UEFI-based systems can utilize all 3TB right out of the box. Seagate delivers industry-leading quality and construction in all of their products, and the high-performance/high-capacity Barracuda series is the end-result of years of proven industry experience.

Available as of 1 November 2011, the three-platter Seagate Barracuda ST3000DM001 hard drive presently sells for $170 at Amazon. This works out to less than $0.06 per gigabyte of storage capacity, which is pennies on the dollar in comparison to SSD technology. To put things into perspective with SSDs, a hypothetical 120GB Barracuda HDD would cost less than $7 - or roughly 5% the price for any solid state drive of the same capacity. For storage-hungry gamers and performance enthusiasts wanting performance and high-capacity storage, the Seagate Barracuda is an exceptional drive with plenty of value.

Based on the current condition of today's desktop storage market, it's still very much a hard drive friendly world. While SSD technology will eventually replace hard disk storage some day soon, there's no evidence as to when solid state storage can match capacity at the same price point. The 3TB Seagate Barracuda Hard Drive ST3000DM001 resists that forthcoming change for at least a while longer, and its massive three-Terabyte capacity paired to the future-proof SATA 6Gb/s interface will certainly help punctuate this. The affordable cost to capacity ratio puts the Barracuda ahead of SSDs by a long-shot, while still offering respectable bandwidth performance speeds for enthusiast computer systems. Now capable of 1TB platters, it won't be long before we see 5TB hard drives.

I just finished retesting my two Western Digital Caviar 640 Blacks and used a lot of the same tools you did. (My reasons weren't to compare this drive but other tests I was doing unrelated.)

One of the things I wanted to do was test using real files. I chose to use a folder with 6GB of jpg/RAW/and video files. I then compressed that entire folder into a solid RAR archive and tested with that as well. Synthetic benches are fun, but real world file transfers can tell a different story.

All in all a tight review, but I'm wondering why you didn't test the drive using real files, say reading from an SSD and writing to it?

I could have used real files, but felt I already had enough tests completed to illustrate performance. When you use real files, they must be the exact same files every time. Compressed files (mov/avi/mpg/etc) also skew results depending on the SSDs used.

When you say "skew" results, you mean because SSDs take into consideration compressible files as opposed to uncompromisable files? If so, that's why I created a compressed RAR file and the folder with loose files in it. It would have just been nice to see two real world file transfer scenarios, as per above. Maybe I'm off base here. If so, disregard.

I've done some comparisons like this during my NAS tests: "Instead of one 10 GB file, the green portion of the chart shows what happens when transferring 4,793 items totaling 6.5GB from the PC to the NAS. If you're going to use any NAS for basic backup duties, this is the kind of action it's going to see." My informal tests showed that the real-world examples introduced too much variation in the results, making comparisons difficult and/or misleading.

Still, I get your point, and I also wish there was a way to use a standardized set of test files, that everyone could agree on.

Since here only two drives were being compared to each other, the same files could have been used for both drives. One, as explained above, multiple file, and the other one large file. Because as you point out, drives act differently depending on what is being transferred.

I suppose you could save those same files and use them to test other drives also, albeit, with the same drive and rig set up. Or, one could test a number of drives using the same files on any rig, as long as the host drive, to prevent bottlenecking, is faster than the drive being tested. That SSD Olin tested recently would have been a good contender for the host drive, since it is the fastest SSD currently commercially available to the public.

does this drive work with sata 2 raid controllers?

Yes, SATA 6Gb/s is backwards compatible with SATA 3Gb/s and 1.5Gb/s.

I have both the Workstation and the Sabertooth motherboards with the P55 chipset and if they are the same as the X79 the Sabertooth compared to the Workstation are the same my p55's. The Sabertooth was able to OC 300 mhz more then the workstation 4.3Ghz for the Workstation comaper to the Sabertooth able to clock to 4.6Ghz.
