RPM of 4TB My Book HD

Hello. Do you know the rpm of the 4TB My Book HD (WDBFJK0040HBK-EESN) works???

I don’t  know if it works at 5.400 rpm, 7.200 rpm or another rpm.


Hello, this type of information is not available. Check the link below for more information. 

What kind of hard drive is inside a Western Digital external product?

 I checked the link and basically assure you the ability , nothing more. Just say : We cannot guarantee a particular internal hard drive model, data interface, rotational speed, or cache size in the external hard drive enclosure.


Thanks anyway. A greeting
