1 Can anyone point me to an article or some tips on my I should be setting
2 in hdparm to tune my SATA setup to get some more thoroughput? I have 4
3 Seagate SATA drives plugged into an Escalade hardware Adapter running
4 RAID 10. Here's what I am currently getting from HDParm:
5
6 localhost ~ # hdparm -Tt /dev/sda
7
8 /dev/sda:
9 Timing cached reads: 3244 MB in 2.00 seconds = 1621.90 MB/sec
10 Timing buffered disk reads: 150 MB in 3.04 seconds = 49.40 MB/sec
11
12 localhost ~ # hdparm /dev/sda
13
14 /dev/sda:
15 readonly = 0 (off)
16 readahead = 64 (on)
17 geometry = 0/64/32, sectors = 500116226048, start = 0
18
19 I went through the man page, but its seems like everything there is
20 geared towards IDE drives.(?) Or does it all apply to SATA? Thanks, I
21 really appreciate it. :)
