Search this GRE forum for earlier posts about the -800 scanner. There are some good tips, especially from Troymail and Jay911. I had one of these scanners and used a 32GB card. It took several seconds upon powering the unit, as it indexed the files on the card. 32GB will hold alot.....more than you'll likely need. Ever.
Moral = the larger the card and data contained within, the longer the index time.
