Hi,
There are 2 HDDs with BDE offered as options on the T6x.
I suppose the encryption is performed at the HDD level.
What's the impact on HDD performance?
TY

The last time I checked, Hitachi claimed there wasn't any performance impact. For two reasons:
1. The encryption is hardware based.
2. The AES algorithm is very fast.

i can confirm that.
i have bitlocker running for a while now and there are no noticeable performance tolls. installation/writing/reading are just as fast.
