Does BitLocker slow down PC?
If you are currently constrained by storage throughput, particularly when reading data, BitLocker will slow you down.
Can BitLocker be hacked?
A researcher has found a new attack method that can extract BitLocker encryption keys. As a result, the attack puts the security of the stored data on target laptops at risk of hacking. This attack method requires physical access to the target device.
What happens if I turn BitLocker on?
On a new hard drive, encrypting just the used spaced can be considerably faster than encrypting the entire drive. When this encryption option is selected, BitLocker automatically encrypts data as it is saved, ensuring that no data is stored unencrypted.
