difference between NAS and Enterprise drives
Hello,
I am looking to purchase a few low cost drives for a RAID array in various servers using either LSI 9271-8i or Adaptec 5805 RAID controllers (i have many of each). What I am trying to determine is what drives I can get away with purchasing. I see NAS drives cost less than enterprise sata drives, my concern is if they will have similar problems to consumer grade sata drives. I have been able to determine that NAS drives have slightly higher vibration and are a little slower than enterprise drives, but other than that, no differences are noted. The higher vibrations limit the NAS drives to a maximum of 4 in an assembly or physical mount to keep vibration from becoming an issue that degrades a volume. Can anyone add to what I have found or for that matter correct me on anything?

@stampel - do you know if NAS drives will have problems with RAID arrays degrading like desktop drives do?

i'll use 4 max. apparently to higher the number of drives the higher the vibration level which can cause problems. I would like RAID5 for the space, but i may use RAID 10 as well. depends on the need.

You can read this article which will explain it better than I can.
