Well, I think using the high density drives whether it's 1.44 or 1.2
on XT will definitely be slow. First, the disk controller operates
in 8 bits slots as compared to 16 bits in the AT. So, even though
you may have Turbo Speed, you are still restricted to slower bus.
Secondly, the huge amount of data on the high density disk can slow
down the access time significantly. 

The only thing you can do to alleviate the problem without getting
an AT is by using cache program, or use program like fastopen in Dos 3.3. 
Also, if you want to copy the disk to your harddisk, use xcopy program 
instead of normal dos copy. Xcopy reads as much as data into memory and
write it on the target drive. So, you don't have to read and write so
many times. All these methods may improve the disk performance.

I hope it answers your question.
