The results are interesting:
This is the WD10EARS drive, with both /home and / mounted on it in
separate partitions:
✈ganymede:~$ dd if=/dev/zero of=/home/dotancohen/test.t count=100000 bs=8192
100000+0 records in
100000+0 records out
819200000 bytes (819 MB) copied, 7.96557 s, 103 MB/s
This is an older 160 GB IDE Western Digital drive, that "felt" faster
when both /home and / were on it (also in separate partitions), but
now the whole drive is /home/music:
✈ganymede:~$ dd if=/dev/zero of=/home/music/test.t count=100000 bs=8192
100000+0 records in
100000+0 records out
819200000 bytes (819 MB) copied, 12.1413 s, 67.5 MB/s
This is an older 400 GB IDE Western Digital drive that "felt" no
different than the 160 GB unit, that now serves as a backup drive
despite it actually being in the same case (I move backups offsite
once a month):
✈ganymede:~$ dd if=/dev/zero of=/home/backup/test.t count=100000 bs=8192
100000+0 records in
100000+0 records out
819200000 bytes (819 MB) copied, 13.8581 s, 59.1 MB/s
✈ganymede:~$
So despite the "feel" of the drive, the green SATA drive blows the two
"snappier" IDE drives out of the water. I wonder why this is,
obviously the bottleneck is not the hard drive. I'll run memtest
tonight, we'll see where that goes. Anyway, I hope I haven't hijacked,
but this thread sure was interesting!
