Nor past nor current. Market is geared exclusively to the profit. So while at past there was huge risks of making incompatible and thus poorly sold product, now it's cheaper to resize sectors than research magnetic recording technologies, because all current versions of major OSes support 4k sector size.

As I sad before "4k sector is not a bad idea alone", because all current file systems have allocation unit size of 4k or even more. And of course it's more efficient to store just one piece of error correcting codes per 4K than for every 512 bytes. But on the other hand, stronger error correction algorithms used more space for error correcting codes and format efficiency gains resulting from the 4K sector structure range from five to thirteen percent only. So while it might be considered as a logical step forward, it is definitely not a silver bullet in storage space advancement. ------------------------------------------------------------------------------ Xperia(TM) PLAY It's a major breakthrough.
