[K12OSN] new server serial ATA or SCSI

[Matt Loretitsch]

What sort of IDE drives are those on the third server?  Interesting
comparison!

Two WD400BB IDE Drives on a relatively new SOYO mobo (cheap development
server) 1.7ghz celeron chip

Raid-0 through linux i.e. not hardware

/dev/md0:
 Timing buffer-cache reads:   128 MB in  0.85 seconds =150.59 MB/sec
 Timing buffered disk reads:  64 MB in  1.47 seconds = 43.54 MB/sec

/dev/md1:
 Timing buffer-cache reads:   128 MB in  0.84 seconds =152.38 MB/sec
 Timing buffered disk reads:  64 MB in  1.15 seconds = 55.65 MB/sec

/dev/md2:
 Timing buffer-cache reads:   128 MB in  0.84 seconds =152.38 MB/sec
 Timing buffered disk reads:  64 MB in  1.08 seconds = 59.26 MB/sec

/dev/hda1:
 Timing buffer-cache reads:   128 MB in  0.78 seconds =164.10 MB/sec
 Timing buffered disk reads:  64 MB in  1.47 seconds = 43.54 MB/sec

Just some comparison for the group from me.  A big hello to the buffered
reads on SATA!
