Iskreno, neznam detalje puno više od vas. Mislim da su to novi EARS (1, 1.5 i 2TB) te AARS (640 i 800GB) modeli. Evo i popisa pa scrollajte do Green serije i proučite specifikacije.

Evo link za koga zanima taj Advanced Format na novim Green diskovima.

For quite some time now, mechanical hard drives have stored data in 512-byte chunks called sectors. That sector size worked for lower capacity points, but as areal densities rise, it's become increasingly inappropriate for new drives. As a result, the industry has decided to transition to a 4KB sector size dubbed Advanced Format.

So-called legacy formatting schemes sandwich each 512-byte sector between Sync/DAM and ECC blocks that handle data address marking and error correction, respectively—and also take up space. You still need those blocks with Advanced Format, but only every 4KB rather than every 512 bytes, which translates to a dramatic reduction in overhead. This approach allows Advanced Format to make more efficient use of a platter's available capacity, and Western Digital expects it to boost useful storage by 7-11%, depending on the implementation. Current 500GB/platter products stand to see an increase in useful capacity of about 10%, which is really quite impressive.
