Samsung SSD: Hardware encryption and speed

I concern about speed changes of the Samsung MZ-M5E1T0BW 850-EVO when hardware encryption/decryption is enabled. I can't find any information in the data sheets. Do you guys know if there is a (significant) loss of read/write speed when the hardware encryption is enabled? Thanks!

Solution 1:

The performance drop with Samsung Self Encryption Drive (SED) is quite small. This review reports SED offers twice the speed of software encryption in this test.

                  SSD no encryption    SED
Large Data Read   178.00               169.33
Large Data Write  170.80               164.50
