The latest MG04ACA series from Toshiba is aimed towards enterprise applications and these are available with different capacities: 2TB, 3TB, 4TB, 5TB or 6TB. Depending on the sector size, we have models ending with E, which do also have 512 B sector emulation and support legacy applications and operating environments which require sectors of this size, but also models ending with A, which lack this emulation capability. For the drives which are available to emulate 512 sectors, Toshiba also introduces the Persistent Write Cache Technology for Data-Loss Protection in a sudden power-loss event.
