I have a Lenovo Thinkpad T530 with an Intel SSD 250GB drive with TPM v1.2.
Installed fresh Windows 10 TP and started BitLocker to encrypt the entire drive.
The encyption have been working for two days now and still only encrypted 4.9%
How long time does it really take to encypt? I don't remember Windows 8.1 taking this long time.
