In recent years, however, Serial ATA drives spinning at a mere 7,200RPM have become increasingly popular for applications that favor storage capacity and cost over performance. Seagate and sustainabilityOffering convenient personal banking & business banking solutions like checking, savings, lending, mortgages, online banking & mobile banking, and more.Enterprise storage used to be dominated by expensive SCSI solutions with lofty spindle speeds. In fact, Pipeline HD drives support a comprehensive sustainability value proposition. And Seagate is committed to environmental stewardship that goes beyond reduced power consumption. Pipeline HD hard drives meet a rising demand for energy-conserving consumer electronics without compromising performance.

Get it as soon as Wed, Aug 18. These drives are based on desktop models, but they tend to undergo more stringent reliability testing, benefit from additional features, and come equipped with firmware tweaked to improve performance with demanding enterprise workloads.99. Standard desktop drives simply wonвЂ™t do, which is why hard drive manufacturers have developed SATA drives with enterprise-class credentials. Enterprise customers are a discerning lot, and theyвЂ™re particularly, er, particular about reliability, power consumption, and suitability for multi-drive RAID environments.

Seagate technically makes versions of the ES.2 with 16MB of cache. There are also differences when it comes to cache all ES.2 capacities enjoy a full 32MB, but with the 7200.11, 500 and 750GB flavors are also offered with 16MB. 96The ES.2, for example, is available as a single-platter 250GB drive, while the lowest 7200.11 capacity is 500GB.

Seagate says PowerTrim has no impact on overall performance, and given the companyвЂ™s own power consumption specifications, it appears to be implemented in the Barracuda 7200.11, as well. To help improve its energy efficiency, the ES.2 features a dynamic power optimization scheme called PowerTrim that can selectively shut down portions of the drive that arenвЂ™t in use. SAS models are rated for idle power consumption of 10.2W, with typical power consumption pegged at 13.0W.Power consumption is an important metric for enterprise customers looking at running not just one drive, but servers, racks, or even rooms filled with them.

Both drives are covered by a five-year warranty however, the ES.2 is rated for a mean time between failures (MTBF) of 1.2 million hoursвЂ”much longer than the 7200.11вЂ™s mere 750,000 hours. Interestingly, the ES.2 owes much of its vibration tolerance to firmware tweaks that you wonвЂ™t find in the 7200.11.The ES.2 also differs from the 7200.11 when it comes to reliability specs. Such interruptions can degrade performance, which is why Seagate is quick to claim that the ES.2 has the highest rotational vibration tolerance in its classвЂ”12.5 Rad/secВІ at 1500Hz, to be exact. If vibrations become too severe, drives may interrupt operation to prevent catastrophic head crashes. When you have multiple drives sandwiched together in the same enclosure, vibrations produced by the mass of spinning platters and seeking actuators make it more difficult for drive heads to stay on track.

The other drives arenвЂ™t explicitly labeled as NCQ drives because theyвЂ™re not available without NCQ support.Finally, we should note that our WD1500ADFD has a slightly newer firmware revision than the Raptor X sample weвЂ™ve had since February 2006. To avoid confusion, weвЂ™ll be listing their capacities in parentheses in each of our graphs.Since Seagate makes versions of the 7200.7 both with and without NCQ support, the 7200.7 in our tests appears as the вЂњBarracuda 7200.7 NCQвЂќ to clarify that itвЂ™s the NCQ version of the drive. Our Intel 955X-based test platform doesnвЂ™t support TCQ.We have test results from several versions of Western DigitalвЂ™s Caviar SE16 and RE2. The WD740GD does support a form of command queuing known as Tagged Command Queuing (TCQ), but host controller and chipset support for TCQ is pretty thin. That sounds impressive, of course, but an order of magnitude in this case is the difference between 10 15 and 10 14.Note that the 250GB Caviar SE16 and the Raptor WD740GD lack support for Native Command Queuing.

Most of our analysis will be limited to how the ES.2 compares with its direct rivals, so it should be easy to follow along.All tests were run three times, and their results were averaged, using the following test system.Radeon X700 Pro 256MB with CATALYST 5.7 driversWestern Digital Raptor WD1500ADFD 150GB SATAThanks to the folks at Newegg for hooking us up with the DiamondMax 11 we used for testing. We also have two sets of IOMeter graphs: one with all the drives, and another with just the Barracuda ES.2 and its direct rivals. YouвЂ™ll also find results from the Raptor WD1500ADFD highlighted in pale yellow to illustrate how the ES.2 compares to an enterprise-class SATA drive spinning at 10,000RPM.
