“The Seagate Cheetah 15K.7 is a remarkable product, no matter if you see it as an enterprise tool or through the eyes of an enthusiast...” - TweakTown, November 2009 “In conclusion, the Seagate Cheetah 15K.7 SAS drive has demonstrated a dominance over existing Enterprise storage solutions and improved file transfer speeds at the same time as it saves electrical energy costs.” - Benchmark Reviews, October 2009 “So after taking a look at the Seagate Cheetah NS.2 and Cheetah 15K.7 I can say one thing without a doubt, these are two of the fastest hard drives we have seen. In fact the 15K.7 is just short of SSD performance with the reliability that only 53 years of development can give you.” - Lanoc Reviews, October 2009

	“For users looking for the most advanced technology to create new premium systems, or those who are looking to extend the life of their existing systems, the Cheetah® 15K.7 delivers the low TCO and promise of easy integration for businesses of all sizes...” - Joe Cousins, vice president of marketing, Bell Microproducts

5.0 out of 5 stars 2010 Storage Speed and Size, October 30, 2010

By 

Christian Girard "SuSEKing" (I am a citizen of the world taking refuge in the USA) - See all my reviews

In 2010, this drive is the fastest, production spinning disk drive that money can buy. Often you read a disk drive's specifications and glowing online reviews, but when you install the drive in your system, the drive is mediocre or a minimal improvement. I guarantee that situation is not the case with the ST3600057SS. I ran a pair of Fujitsu 15K rpm SAS drives for several years. Nearly two years ago I upgraded to a Seagate 15K rpm SAS 450GB drive, which provided a considerable performance improvement over my trusted Fujitsu drives. Last year I purchased a ST3600057SS and was astonished at its performance. When I say performance, I am basing it output from seeker v2.0, hdparm -t, and my subjective impression from using the computer. The seeker program reveals all of the 15K rpm SAS drives to have 3 - 5 ms average access time, which is to be expected for a 15K rpm SAS drive. The Fujitsu 300GB drives averaged 136 MB/s, the Seagate 450GB drive averages 166 MB/s, and the ST3600057SS averages 201 MB/s. To put the ST3600057SS' performance in perspective, my 64GB SSD Mushkin MKNSSDCL averages 235 MB/s.

A caveat here is that I am using an LSI 3GB/s controller card and I believe that the performance slightly increases with a 6GB/s SAS controller card.

The ST3600057SS is the quietest 15K rpm drive that I have ever owned. I seldom hear it during normal use. The drive's temperature average is 36 C, but it is in a fan cooled drive cage. I have had absolutely no bad sectors or any drive-related problems with the ST3600057SS. However, in 6+ years working with SAS drives, I have not experienced a failure or fault. The 15K rpm SAS drives are enterprise quality so you get exceptional reliability.

This year I added a second ST3600057SS so that I could run a BTRFS RAID0 configuration. My only comment is WOW. I wholeheartedly recommend this drive. You get SSD-type performance at a much better $/GB ratio.

Got 4 of these from Amazon at very good price. Drives are super fast, running HyperV with a bunch of VMs.

I see lots of people benchmarking their drives, getting insane speeds. This one tops at 150-170MB/s dropping below 100 at the end of the platters in HD Tune on a SAS 9260-8i controller, Supermicro motherboard and dual Xeon X5650.

Windows 7 disk score was 5.9. It's been reliable for a couple of months, no problems here.
