You are comparing the fastest writable memory available (SRAM) vs biological non-volatile memory that is essentially read only. Samsung's 280 layer NAND reaches 28,5 Gbit per mm^2. I don't know how you would convert that to a volume, but if we simply multiply by 1000x for simplicity, it would be much closer to 0.19 Mbit/μm³, but even then you have to remember that NAND flash is still writable at pretty high speeds.
- FloorEgg 1y agoThis is true, I was only comparing functional information density (unique functional genome bps), not read/write speeds. I was also taking the information from a genome and then dividing it by the volume of a cell, but there are many instances of the genome in a cell. I didn't count all instances because they aren't unique. There's a lot to unpack with this comparison and my approximation was crude, but the more I've dug into this comparison the more apparent how incredibly efficient life is at managing and processing and storing information. Especially if you also consider the amino acids, proteins, etc as information. No matter how you slice it, life seems orders of magnitude more efficient by every metric. I'd like to think there's a paper somewhere where someone has carefully unpacked this and formally quantified it all.
