I'm certainly frustrated by Blu-ray sizes compared to Flash cards.

I've been told that 50GB is a bit more risky for archival because you're then dependent on the laser refocusing for playback on a dual layer disk. 25GB is obviously too small to archive 32GB Flash cards. Sony Clip Browser can split BPAV folders but I have not found the equivalent for AVCHD (BPMV) folders.

I'd really like to see high capacity single layer Blu-ray disk . . . at a "reasonable" price.

BTW from everything I read, Blu-ray isn't at all like DVD when it comes to archival. The Blu-ray surfaces (and the lasers) supposedly are much less likely to impacted by scratches or blemishes that occur over time and the layering process of the substrate to surface is much less resistant to short term decay. While they don't last forever I suspect the claims of 50 years are far more substantial compared to some "bargain" DVDs that could break down after a couple of years or be rendered useless with a single minor surface scratch.
