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.....

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...

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=N82E168...
Sequential Access - Read:up to 285MB/s

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).
