    SATA 15K vs SCSI 15K vs SAS 15K ?

    Hi,

    I wonder which drive give the best performance? Look like they all have the same 15000 rpm. :d

    Any experience?

    Where are you seeing 15k RPM SATA drives?

    15k SAS and SCSI will generally give equivalent performance, as they're basically the same thing. Only real difference is the dedicated bandwidth on the SAS ports, which would be useful if you're maxing out a SCSI interface, which generally isn't the case.

    There is no such think as a 15k sata drive, there are 10k rpm sata drives, but that is the max.

    The fastest of the 3 are 2.5" 15k rpm SAS (serial attached scsi). The normal scsi drives are still a good option as they are faster than the 10k sata and in some cases they are cheaper than the 10k rpm sata drives.

    Well, that depends. On the 2.5" SAS drives you'll generally get higher access times, but lower max throughput numbers, thus it depends on the type of data being served. That is at least according to a couple benchmarks I had seen.

    I am going by our own tests, all of our tests are in raid setups are most of our clients use the faster drives for DB server or high speed NAS setups. But yes, if its used for raw reads of single huge files, more platters = faster transfers, however this is rarely needed in the webhosting world.

    small 2.5" sas 15k will give you best preformance, especially if you have 8 of them in raid 0
