Thanks for the info. Some followup questions:
Can Bitlocker be used with UEFI?
Is it effective on SSDs?
Shouldn't be any less effective from a security standpoint than on a mechanical drive. There might be some other implications though (e.g. I am not sure if it reduces the effectiveness of TRIM).
All of my hard drives are SATA, but some are a few years old. How can I check my hard drives to confirm whether or not they have TPM?
TPM is a feature of the motherboard, not the drives. Some motherboards have a socket for an optional TPM module.
Is it fair to say that Bitlocker (and the others) are good for preventing the casual hacker from accessing my data but not the experienced or persistent one?
Properly used, it should even be resistant to experienced/persistent hackers.
