Timing buffered disk reads: 64 MB in 2.71 seconds = 23.62 MB/sec

I would hope that reiserfs is faster then a FAT32 partition in linux or is that just a typo and you really meant sda5.
From what I've read: reiserfs is faster with smaller files, jfs is faster with big files. ext3 is just an ext2 with a journal but you can still use all of the ext2 disk utilities if you remount it as ext2.
ext3 and fat32 always run about the same speed for me. This was not a typo just a messup. I meant to test sda5. I will test the ext3 partition when I get home. But I'm confident that the fat32 and ext3 will be the same. I have tested the ext3 partition 2 days ago against the fat32 partition and they were the same. But I will post the actual results just the same.
Does anyone else care to post some comparisons also?
setting 32-bit IO_support flag to 1
setting using_dma to 1 (on)
setting keep_settings to 1 (on)
IO_support = 1 (32-bit)
using_dma = 1 (on)
keepsettings = 1 (on)
Is there an advantage to having 'using_dma = 3' as opposed to 'using_dma=1' ?
Also, what about setting the read ahead on ? How did you do that ?
And last, does the 'keepsettings=1' function mean that you only have to set things one time ?
Currently, I have the entry 'hdparm -d 1 -c 1 -k 1 /dev/hda' in my 'rc.local' file so that it sets it every boot.

Never had to mess with hdparm to alter the original settings except when I misconfigured my IDE_BLK_DEV in the kernel.
Same for my older P3/Via133a-ATA66, ...which scores in the wherabouts of Dalek's numbers ...iirc, not booted atm.
