High-capacity SSD-type devices have more than one NAND chip. Yes, the capacity of a single chip can be lower than that of an array of them. And ECC is mostly done in hardware these days; it's harder to make stupid and conflicting design decisions in different pieces of the software. Although some people can always manage... ☺
"eMMC + F2FS might have decent and reproducible performance, but another vendor SD + VFAT optimised FTL + F2FS might not bring the same benefits ?"
I wouldn't go that far. I'd say that F2FS might have decent performance on the specific devices that it's been optimised for — but another device, even from the same
vendor and even the same
model number, in the future may behave entirely differently. And all your optimisations^H
layering violations might be counter-productive.
