Touting a perfect 5/5 score in recent tests at Club Overclocker this past week, the latest Seagate nearline drive, the Constellation ES wowed their reviewers with its 6Gb/s SAS performance. Tested in a real-life nearline environment, the multiple drive solution outperformed the expectations of this savvy test team calling the Constellation ES a “no-brainer”. “RAID 0 test results with 3 hard drives were nothing less than amazing … data transfer rates just keep increasing by leaps and bounds”.
Driven by the LSI MegaRAID SAS 9260-8i RAID controller in this test, the Constellation ES with its SAS interface not only provides higher levels of data integrity and proven scalability, but you can expect “monstrous” performance the more drives you add to your system — Up to 51% performance increase in sequential reads when you move from one to three drives in the Crystal Disk Mark read/write tests. The HD Tune average read test saw an increase of 71% in average MB/s in the three drive configuration over a single drive configuration. 
And as the article points out, the best part is you get all this performance while keeping your environmental footprint at a minimum with its low power consumption.
Read the article for yourself and see why the writer comes to the conclusion of: “If I were to build a server or high performance workstation, SAS 2.0 would definitely be my 1st choice.” While Seagate’s enterprise development team knows that nearline SAS is the most robust solution for high capacity, multi-drive systems, we hear the rest of the competitors may finally be catching on. How sassy is that?
