Tested: Windows 11 Pro’s On-By-Default Encryption Slows SSDs Up to 45%::Windows 11 Pro defaults to BitLocker being turned on, using software encryption. We’ve tested the Samsung 990 Pro with hardware encryption to show how the various modes impact performance, and how muc
Deliberately using software encryption mode is slow; no shocker there. Their same testing showed no significant difference when hardware encryption mode was used.
There’s a reason they default to software though, the hardware can’t be trusted:

Sure, but I suspect this is the real motivation for the article:
It sounds like many people may be using software encryption without realizing it, if Windows 11 Pro uses it by default.
How does one use hardware encryption? Is that a feature that is ssd dependent?
It’s SSD dependent and implementation quality may vary between manufacturers and models. Some may not actually protect your data all that well from someone trying to access your data, hence Microsoft defaulting to software they know works.
