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

Presumably you’re relying on the security of your home, and if that’s broken you’ve got bigger things to worry about.

Completely valid point. The kind of non-technical people wouldn’t likely notice any difference in SSD speed anyway. It would be nice if they made it easier for technical people to disable the feature.
Yeah, but normally FDE overhead is so low, you may as well encrypt.
That’s one issue I had with this article. It doesn’t do any actually tests to compare it to other OS implementations. How can we condemn Microsoft for 45% slower speeds (in a specific benchmark on specific hardware) when there’s no context to compare it to? And this claim is specifically only for software encryption where hardware level encryption is not available. Is it Windows 11 that’s specifically causing this, or is it a general problem?
Comparing to macOS is actually impossible because fde can’t be turned off on Macs at all. Macs (and iPhones etc.) handle encryption of internal storage transparently in hardware at pretty much no overhead and without the CPU even having access to the key. You can only choose whether a login is required for the Secure Enclave hardware to be able to access the key.
On other platforms it’s pretty much a hardware question too. PC vendors and hard disk vendors could do the same thing Apple is doing regardless of whether the OS is Windows or Linux or whatever. How fast the OS based encryption is only matters on hardware that doesn’t have this functionality.
Exactly right. To me it seems overly clicky baity to specifically condemn Windows 11 for the overhead of software based encryption because the hardware doesn’t support it. The same problem exists across all platforms (hypothetically) if there is no hardware support.
It would have been another thing if they could show this problem was unique to Windows 11, or if they focused on the fact that it was difficult to disable. Instead they put so much effort into saying Windows 11 runs 45% slower due to Bitlocker.
What was telling for me was the article from the same site from a few years ago about Microsoft disabling the use of hardware encryption by default because they couldn’t trust the drive manufacturers to do it right.
Do they want things to be secure or fast?
Did you even read the article?
The configuration has a powerful cpu and fast ssd. There are multiple benchmark tools used, and 2 encryption methods, software and hardware.
Yes I did and everything you pointed out does nothing to address my comment.
How does pointing out that they did tests with different CPUs and SSDs, multiple benchmarking software, and different encryption methods do anything to address my complaint that they did not comment on whether this is a Windows 11 specific issue? Did you even ready comment?
It’s largely useful on mobile devices because you can easily forget them somewhere and all a tech savvy person has to do to get the data is remove the HDD (if it’s a laptop), or if it’s integrated, reset the admin password with something like NT Offline Password Reset. Smartphones are another can of worms I won’t get into, but I’m sure you understand.
With a desktop, it’s highly unlikely you’re carrying it around and will forget it some place. The only way someone can get the drive is to break into your residence and physically remove the drive, and as someone else said: if someone is breaking into your residence to get a HDD out of your PC, you have bigger problems.
