As far as I know, no other popular full-disk encryption (LUKS, geli, FileVault) delegates to the SSD’s hardware encryption (by default, anyway) as BitLocker apparently does [0]. Anyone know otherwise?
"although one would hope those are actually secure considering how much they charge for it"
Considering BitLocker requires a Windows purchase (unless you pirate it) and LVM costs exactly $0, I think it's safe to say that the amount of money thrown is not a good indicator of actual security.
