thats like uber slow.

here are my results:

ReadyNAS-Pro:~# hdparm -t -T /dev/c/c

/dev/c/c:
 Timing cached reads:   1724 MB in  2.00 seconds = 862.13 MB/sec
 Timing buffered disk reads:  730 MB in  3.00 seconds = 243.30 MB/sec
ReadyNAS-Pro:~# hdparm -t -T /dev/c/c

my iperf is probably faster because i used the option -P4 which spawns 4 parallel streams instead of just one.

i havent got a clue why the hdparm speeds differ so much from yours though.
