[comp.sys.ibm.pc] Hard Disk on a Card?

	Forgive me if this has been brought up here recently. Has anyone
	had any experience with Hard Drives on a card, one that you plug
	into an unused slot? Specifically, what are the limitations of such 
	a device? How would it differ from a "real" hard disk. Having had 
	no luck installing either a Seagate or a Connors drive on my AT 
	compatible, I was wondering about taking this route.

Well, I've used a Plus HardCard 40.  It used to be that Hardcards did not have
the speed or capacity of regular hard disks.  That seems to have changed now,
with Plus coming out with the HardCard ][ 80 MB drive that claims to have an
access time of 19 ms (I haven't used the HardCard ][; I don't know if it's
really this fast).  Still, it's certainly faster than the 40 ms access times
they were giving a couple of years ago.  The advantages of a HardCard are ease
of installation and low power consumption.  The disadvantages are the high cost
compared to regular drives of similar capabilities.
