Re: DASD

[Scott Klement <klemscot@xxxxxxxxxxxx>]

The DASD on the AS/400 are higher quality drives.  Made with better
components, etc.  Engineered for reliability instead of cost.  (You do
know that PC hardware is engineered to determine how they can make it
the cheapest, don't you?)

DASD on the AS/400 also automatically verifies that what it's written 
is what it intended to write -- that the data is not corrupt.   It'd
be like running a PC with scandisk running constantly, except that it's
done in hardware and doesn't take away CPU cycles.

Does that help?
