[M] Toshiba P300 6TB Desktop PC Hard Drive Review
 

Over the previously tested P300 4TB, the 6TB version has improvements regarding both read and write speeds, but in regular operation the two drives will perform about the same. What is to be appreciated here is the increased storage capacity, while keeping the noise levels and power consumption to a minimum. We have performed out testing without a direct airflow to the drive, and never seen temperatures raising over 33 degrees Celsius, meaning that the product will operate fine in cases with less than decent ventilation as well.
