Not particularly.  That is from my main workstation now (K7 1Ghz) with
the following configuration:

# hdparm /dev/hda

/dev/hda:
 multcount    = 16 (on)
 I/O support  =  1 (32-bit)
 unmaskirq    =  1 (on)
 using_dma    =  1 (on)
 keepsettings =  1 (on)
 nowerr       =  0 (off)
 readonly     =  0 (off)
 readahead    =  8 (on)
 geometry     = 9729/255/63, sectors = 156301488, start = 0
 busstate     =  1 (on)

A lot of it will depend on the drive and the controller.  For instance on my
older workstation (K7 650Mhz), I get the following:

# hdparm -Tt /dev/hda

/dev/hda:
 Timing buffer-cache reads:   128 MB in  0.92 seconds =139.13 MB/sec
 Timing buffered disk reads:  64 MB in  2.81 seconds = 22.78 MB/sec

with an indentical configuration.  However, turning off DMA on both of them
gives:

K7 1Ghz
 Timing buffered disk reads:  64 MB in 27.80 seconds =  2.30 MB/sec
K7 650Mhz
 Timing buffered disk reads:  64 MB in  7.28 seconds =  8.79 MB/sec

I normally use "hdparm -c1 -d1 -k1 /dev/hda", of course you'll want to change
the /dev/hda to whatever drive you're working with.
