Some of you will remember the Hardcard 20<http://en.wikipedia.org/wiki/Hardcard>, which you would have found in a slot on the IBM PC (among others) to easily add a hard disk to a floppy-only computer... this was 20 megabytes on a card. Take a look at the new LSI Nytro Megaraid<http://www.anandtech.com/show/5720/lsis-nytro-megaraid-brings-ssd-caching-to-sas-raid-cards>, which will give you a RAID1 capacity of anywhere from 200GB to 3.2TB on a card... that would be like adding (5) zeroes to the original capacity of the hardcard...
