Conclusion

This test session has produced expected results. Newer HDDs are faster than older ones, consume less power and offer a better price/capacity ratio. Thus, it is the right decision to choose newer HDDs for your data storage system (if you consider them reliable, of course).

When choosing a SAS drive for a workstation, it is the acoustic characteristics that may be the crucial factor, but we have not tested them and cannot thrust our subjective opinion about the appeal of particular drives on you. But generally speaking, SAS drives of latest generations can be used in desktop PCs with enough comfort.

The Seagate Cheetah 15K.7 is the indisputable leader of this test session. Its fantastic mix of high performance and large capacity leaves a strong impression. The Cheetah NS.2 must be noted, too. Its lower spindle rotation speed is made up for by higher recording density. So, if you are looking for an HDD for your enterprise data storage system, but do not trust SATA disks, you may want to consider the Cheetah NS.2.

The intriguing performance of the Maxtor drive which despite its respectable age was sometimes competitive to newest models will be discussed in more detail in one of our upcoming reports.

We would like to award the winner of our today’s roundup - Seagate Cheetah 15K.7 - with our Editor’s Choice title as the fastest SAS hard disk drive:
