ServeTheHome – Intel Xeon AMD Opteron RAID Controller Reviews

Just to check some additional 15k rpm SAS numbers, I used three Seagate Cheetah 15k.5 300GB drives in Raid 5 to see what the numbers would look like. The drives are 3.5″ form factor units so they run quite a bit warmer than the 15k.1 2.5″ Savvios that are also in this machine. First the chart:

Did some testing this weekend with the new Adaptec 5805. Since I wanted to see what this card could do, I decided to try it with some cheap Seagate Savvio 15k.1 36.7GB SAS drives. Overall performance is fine, however there was a consistently interesting note in ATTO’s benchmark at 64k. I tried every stripe size imaginable, and there was a distinct fall-off every time in read speeds. I also tried the newest firmware, same result. Truly odd indeed.

Notice the dip in read performance at 64k. This seems to be very strange and did not go away with three different firmware versions.

Two 1.5TB Seagate 7200.11 drives on the ICH10R in raid 1 make a nice setup. The ICH10R is an on-board semi-hardware raid controller making it a very cheap option to use in any home server. The Seagate 1.5TB drives are one of the highest capacity drives readily available in Q1 2009 and have the best price/GB available. Raid 1 is probably the best way to gain redundancy when there are two disks in the system.
