We know which one we'd rather take -- but alas, we came packing the meager 4GB card in our personal phone as we sauntered up to SanDisk's booth at a CTIA press event this evening, not that juicy 32GB bad boy right above it. At the top there you can see the silicon that goes into each and every 32GB microSDHC to come out of the foundry, and it's pretty insane: 8 layers of 32nm 3-bit-per-cell memory. The SanDisk rep we spoke to said that other companies not capable of pulling off the 8 layer trick will be at a significant disadvantage, since they'll need to go with a higher density at the brutal cost of a lower yield rate -- and as we all know, a chunk of silicon that's failed QA is little more than a paperweight (and not a very effective one at that). We'll take three.
