I have the following result on my TP A21P 2629-HSF with Ubuntu Breezy
vanilla :
bernard@m90252x:~$ sudo hdparm -I -t -T /dev/hda

device size with M = 1000*1000: 40007 MBytes (40 GB)
Capabilities:
LBA, IORDY(cannot be disabled)

40min for SECURITY ERASE UNIT.
HW reset results:
CBLID- above Vih
Device num = 0 determined by the jumper
Checksum: correct
Timing cached reads: 600 MB in 2.00 seconds = 299.30 MB/sec
Timing buffered disk reads: 62 MB in 3.03 seconds = 20.47 MB/sec
Your figures are better than mine, but I haven't played with hdparm to
tune the disk yet. Don't confuse the cached reads and the disk reads
rates!
