Just for info, with Enterprise class sata drives, you're right.

For consumer grade sata, they have extended auto retry logic as an
effort not to fail a read from a bad sector.  It can easily take times
like your seeing.  I think the standard drive timeout is on the order
of 30 seconds and then libata sometimes has retry logic of its own.

Especially with PATA drives a 2 minute issue is not out of the
question, since the kernel will step down the i/o speed and retry each
speed as it goes.  And PATA (IDE) has a lot of speeds to try.
