[comp.sys.ibm.pc.hardware] Hard-drive replacement on PS/2 30-286?

EGQ@psuvm.psu.edu (04/25/91)

     I want to either replace my 20Mb hard-drive or add another hard-drive to
the system.  Is there any advantage/disadvantage of a hardcard rather than an
external hard-drive?  How much does the size of additional hard drive memory
affect the speed of accessing the information, or doesn't it?

     Any information of this subject would be greatly appreciated.
