I've got 1 10GB SCSI for the system, and 2 30GB in a Software RAID 1
But I do have one IDE drive, which doesn't get much use, telling me this:
hdparm -acd /dev/hdd
/dev/hdd:
IO_support = 0 (default 16-bit)
using_dma = 1 (on)
readahead = 8 (on)

hdparm -t /dev/md0
/dev/md0:
Timing buffered disk reads: 64 MB in 1.58 seconds = 40.50 MB/sec
/dev/hdd:
Timing buffered disk reads: 64 MB in 2.94 seconds = 21.74 MB/sec
I guess that's reasonable.

Anything look amiss?

Well, my X server is pretty hefty, and a bunch of kdeinit: .... stuff
but nothing out of the ordinary I used to have before I made the switch.
And another thing, the konsole doesn't display man pages correctly. Seems
like something is all screwed up with fonts or something, getting little
squares where the dashes should be, etc. And this is an out of the box
installation. And its the same way on my Laptop as well.

I've been using up2date religiously, and sometimes I use apt-get (for
RPM). But I just don't get it.
Should I recompile the kernel or something? Otherwise, does anybody have
another Linux I can use that works well, and updates well?

It recognized everything I need, I believe.
