High-capacity SD cards are the black holes of digital photo libraries. Eight gigs of storage means months and months of card filling, and (about) zero card emptying. In fact, we’ve become so used to SD cards that we’re now finding ways for our physical prints (yes, people still have those) to live in one too.
The SD Photo Album (currently up for pre-order for 10 Euro or $13.60 American) holds 60 4-by-6-inch prints. That’s the equivalent of about 256 megs of high-res photography.
