Short version: Other than cost, is there any reason not to use a 7200RPM SAS drive in place of a 7200RPM SATA drive in a server with more than a couple concurrent users connected to it?
Long version: Scenario: SMB Client, 50 users, three physical servers. All physicals running Hyper-V (two with 2012, one with 2008R2) Server1: 3 years old, two RAID1 volumes using 15K SAS drives (SBS 2011/Exchange/SQL/file print for 30 users) Server2: 1yr old, RAID 10 using four 15K SAS drives (file/print for 15 users, remote site from the other two) Server 3: 7 yrs old, RAID 1 with two 7200RPM SATA drives (file/print for 15 users) [And yes, I plan on swapping Server1 and Server2's roles so the faster disk subsystem is the one with SQL and Exchange on it.] Possibly relevant: I use DFSR between servers 1 and 2 and would like to have it with server3 as well. I am replacing Server3 with a three year old 1U and I'm torn between giving it four 7200RPM 1GB SAS drives or four SATA drives. Going with 10K or 15K SAS doubles the price of the drives. Reading various links, I read the 7200 SAS drives are either effectively SATA drives with SAS controller, or they're simply slower spinning, higher MTBF SAS drives. I get conflicting information... Either way, a 7200RPM SAS drive array should handily outperform 7200 SATA drives if 10+ users are connected to it, correct?
