[sclug] Hard disk performance question

[Neil Haughton]

Hi,

Hard disk performance question here:

I have two IDE hard drives fitted:

Seagate Barracuda 40Gb 7200rpm on Primary Master  (/dev/hda)
IBM Deskstar 60GXP 40Gb 7200rpm on Secondary Master (/dev/hdc)

The IBM is about 50% slower than the Seagate. Any ideas if I can improve 
this by tweaking? Here are the parametrs and performance figures:

/dev/hda:
 multcount    = 16 (on)
 IO_support   =  1 (32-bit)
 unmaskirq    =  0 (off)
 using_dma    =  1 (on)
 keepsettings =  0 (off)
 readonly     =  0 (off)
 readahead    =  8 (on)
 geometry     = 4865/255/63, sectors = 78165360, start = 0

/dev/hdc:
 multcount    = 16 (on)
 IO_support   =  1 (32-bit)
 unmaskirq    =  0 (off)
 using_dma    =  1 (on)
 keepsettings =  0 (off)
 readonly     =  0 (off)
 readahead    =  8 (on)
 geometry     = 77545/16/63, sectors = 78165360, start = 0

/dev/hda:
 Timing buffer-cache reads:   128 MB in  0.71 seconds =180.28 MB/sec
 Timing buffered disk reads:  64 MB in  1.17 seconds = 54.70 MB/sec

/dev/hdc:
 Timing buffer-cache reads:   128 MB in  0.72 seconds =177.78 MB/sec
 Timing buffered disk reads:  64 MB in  1.66 seconds = 38.55 MB/sec
