SAS: Cheatah 6gb/s 15k vs UltraStar 6gb/s 15k

hello and merry christmas to all of you,

i have been wondering about these 2 drives before i buy one, ultrastar 15k600 sas has 64mb of cache, the cheatah sas 15k has 16 mg of cache.....
i will be using 1 sas drive only, i hope to get the ultimate! fastest in these 2 drives.
i understand these are very new drives and hope someone here will know, i dont need a encripted drive.
thank you kindley

which drive is fastest out of these 2.....

  1. The 15K.7 is a BIT faster than the 15K600 (195 MB/s vs 200 MB/s throughput respectively). See article => http://www.tomshardware.com/reviews/sas-hard-drive,2566-5.html

    If you are looking for a fast drive you may be best off with an SSD with a SandForce controller. I.E. => http://www.newegg.com/Product/Product.aspx?Item=N82E16820227604&cm_re=agility_2_90gb-_-20-227-604-_-Product
    Sequential Access - Read:up to 285MB/s
    Sequential Access - Write:up to 275MB/s
    Power Consumption (Active):2W
    Power Consumption (Idle):0.5W

    thanks for that!
    i had a feeling the cheatah 15k sas was a bit faster, but didnt see or find the test for the 600gb drives...
    i already have a crusial c300 ssd........are you an sas person or ssd or both?
  3. SSD > SAS. Lower power consumption and noise are keys for me.

    EDIT: Let me rephrase... SSD > SAS for a single drive. SAS > SSD for RAID 0 configs (price / performance favors the SAS).
  4. just ordered the 600gb 6gb/s sas seagate cheatah 15k drive.....as soon as they come in there gone......$530. total 2nd day delivery.....im just hooked on sas and scsi....i have a new controller from:Atto H608 HBC, im running my crucial c300 thru it not bad at all.....

    thanks for your help......
