There are lots of strategies for handling the problem. The engineers just need to figure out the trade offs. Robin Fredrik,

Do you see any hopes of IOPS / random write performance increasing as CF/SSD products mature? I get the feeling that this area is moving ahead very rapidly, but perhaps write IOPS is one area where we should not get our hopes up? Really interesting!

I wish Samsung would be a little more forthcoming about their NAND technology. Most of the whitepapers and application notes are several years old.

But, as some multi-giga NANDs enforce the sequential page write constraint, vendors are doing kind-a log based writing operation to avoid writing a whole block every time it gets a page write request. So it doesn't take that much to write a page into NAND. Robin, originally, NAND can write a page rather than a block.
