SD card reader write/read single block

We checked some SDHC Card Readers and we noticed that they are using the Multiple Block Write CMD25 for writing a single sector and Multiple Block Read CMD18 for reading a sincle sector. The SDIO protocol has Single Block commands CMD24 and CMD 17 for writing or reading a single sector.

Does anyone know why the Card Readers are not using the single block commands for treating a single sector?
