CHEETAH 15K.7 SAS 600GB 16MB

Comment:
I bought this to replace my old hard drive, and it works great so far. You also get lots of space to work with.

Considerably quicker than something more than SATA when comparing IOPS, random read/writes, and continuous information reads.Value/GB is justified for enterprise-class.Really high compatibility with any SAS card/board.When in the brown-box, really nicely packaged for shipment. They do run a tiny warm - in a hot-swap SAS6 cage with close to-forced induction they run in the low 40's under any load. They aren't SSD-speed (or RevoDrive) speed...

This drive is one of the fastest spinning disk drives that you can buy, period. When you want ultra-rapidly, they you acquire SSD, but the $/GB is really high. When you want super-rapidly, but huge capacity, then you acquire this SAS drive, which has a far better $/GB ratio, but is a lot more expensive than SATA. On my openSUSE 64-bit box, random access time (using seeker v2.) are five.7 ms whilst throughput (using hdparm -t) is 201 MB/s. Those results are for a single drive, not a RAID0 mixture. The drive is incredibly quiet for a 15K rpm drive. I have not heard any high-pitch whining and definitely no clicking. This is the ideal disk drive that I have ever owned. There are no cons with this drive, none. There are two considerations: Ƒ) cost, but that is consistent with an enterprise, high-efficiency drive. ƒ) heat, my unit sits in a disk cage that has a 120 mm fan and the disk temperature (smartctl command) is 37 C. I am unsure how significantly this temperature would enhance if you did not force air around the HDD. I have had this unit for 13 months with totally superb efficiency. My system drive is a Mushkin SSD and I have two of these Seagates in a BTRFS RAID0 as the user space. I have utilized the earlier version of Seagate, HItachi, and Fujitsu SAS drives, and this latest version is by far the fastest.
