SATA VS SAS
Posted on 2011-05-05
I am trying to decide what kind of Hard Drives would be good for my SBS2011 server ( 2.4Ghz E5620 Xeon CPU with 24-32GB of RAM) – SAS or SATA.
Traditionally I would get SCSI (SAS) w/o thinking too much. But recently I have installed SBS2011 on a on a DELL T110 server with 2.4Ghz X3430 Xeon Processor, 6GB of RAM, Two 1TB 7200rpm SATA HD (RAID 1) for testing and I was impressed by overall performance of the machine. Currently I have several 2003 servers that I manage for my customers all with traditional SCSI HDs (147GB-300GB 10k-15k rpm) running on 4-5 year-old Servers with Xeon CPUs and I think this new DELL server with SATA seems to provide similar or better performance.
That said, I like to hear from people who have installed SBS 2011 on new server hardware - whether or not SATA (either 7200 or 10K rpm) is good enough to run SBS 2011 (with EXCH 2010, but no SQL Server) for about a 20 user network. I was originally considering 600GB 15K 6Gbps SAS, but I am not sure if it is necessary to spend the money on SAS (not that I don't have the money, but I just like to be smart and practical)
Thank you in advance.
