These things are getting huge! But I suppose that in 10 years they will be 512TB holographic or something.
I like big cards because I can leave all shoots on them as additional backups when in the field (no need to erase). I download each day’s shoot as I go, leaving it on the card as a backup. See a more in-depth discussion in Downloading and Backing Up Images In The Field in the DAP Workflow section.

I am starting to wonder If these cards might be an alternative to long term storage solutions, rather then optical or tape back up. If a card was tested and stored correctly what would be the usable and safe longevity of doing storage this way. This card is a bit expensive but 256 GB is not too bad.
DIGLLOYD: the spare blocks (“over provisioning”) of a good 2.5" SSD along with its high level of error correction makes them a better choice than camera cards which have far lower lifetime wear cycles as well. The ultimate is something like the OWC Enterprise SSD, which has 28% over provisioning and a 7 year warranty. That’s total overkill though (designed to be “beat up” continuously)—better to buy the regular versions like the OWC Electra SSD, and buy more of them (for redundancy).
But most people want an external case. My favorite here is the OWC Mercury Envoy Pro EX. Or any of the OWC Mercury Elite Pro Mini bus powered variants with a 2.5" SSD inside. But the cheapest option (again think redundancy) are 2.5" hard drives in USB bus powered cases. This is all assuming less than huge storage requirements.
