The new MG04ACA series from Toshiba is composed from drives which are meant for enterprise, mission-critical applications, while sporting higher transfer rates and capacities. The tested sample comes with 128MB of cache and comes in two versions, depending on the applications it is needed for: with 512 sector emulation or strictly with 4K sector. Make sure to choose wisely which drive is for you and your setups in order to bypass any incompatibilities which may arise.

Being enterprise drives, these are thoroughly tested and come with more fail-safe systems than their desktop-oriented variants; Toshiba rates these models for about 1400000 hours, workloads of 550TB/year and are fully approved for 24/7 operations.

Regarding the drive performance, MG04ACA400A performs much better than the drives we have previously tested and this way it justifies the higher price Toshiba charges for this model which is about 368 Euros. Additionally, system administrators can opt in for the 5TB variant which is about 440 Euros or the 6GB which price is undisclosed for now.
