IDE is a paralell bus that can be run at what are by modern standards low s=
peeds. So implementing should be just a matter of reading the specs and ban=

Not going to be easy. It's a serial link and even in it's initial form=20
it's running at 1.5 gigabits per second. That is WAY beyond what any=20

USB would probablly work but i'd expect the software to be challenging
There are also IDE to sata bridges out there which may work for your=20
application.
How much data are you trying to store? IMO given the interfacing=20
difficulties HDDs are only likely to be worth it if you need more=20
storage than a couple of big SD cards can provide.
