hdparm shows very different results for 2 hard drives
Smartctl shows no errors, but datacenter is suggesting that I switch out the /sda device with a new hard drive. Is that necessary or is there some way I can tweak that?

The hard drive that is in use will obviously be slower. But it looks too slow. There might be something wrong with the drive.
It's either something wrong with the drive, the drive is under heavy use, or the drive is in pio mode. Normally I would expect all drives or no drives to be in pio mode, so my guess is that there's something seriously wrong with the drive. Although it would be worthwhile to take a look at iostat to see if there is just a lot of disk activity going on.
