BitLocker software encryption slows performance. Here's how to fix it.
You're viewing a single thread.
Doesn't really seem like news to me, encryption makes communication slower, that's pretty standard.

Most of SSD already has good encryption methods
Unless you purchase a SED-non FIPS or FIPS SSD, no, they don't
and an easy way to safely wipe data without re-writing each byte.
ATA Secure Erase is a god send for SSD.

Btw, hw-based encryption is always a compromise betwen security, speed and cost. And holes in the blackbox firmware can only be fixed with updates, as long as supported and if the vendor is willing to.

You’re routinely reading and writing multi gig files in daily life? O.o Do you work with video editing or something?
I would see myself saying that not long ago, but now a 50GB game is nothing unusual.
True, but you’re limited in many, many ways before the SSD. Downloading the game? Network bottleneck. Playing the game? GPU/CPU bottleneck. (Not to mention, if a game is attempting to access multiple gigs of stored data every second, there’s likely something wrong with that game.)
Installing the game, absolutely. But you only do that once, and I doubt you’re installing a 500GB game daily.

An 80gb game played in 16gb ram is always going to have work to do.
Yes, the initial install of the game is storage intensive. But again, that happens only once. I doubt you’re doing that very often.

Actually, that’s fair. I forgot some updates are just terrible.

… Then you would disable auto adoption of newly connected drives into bitlocker, would you not?
This is like complaining that the login screen pops up every time for a machine that doesn’t need security. Just change the setting instead of complaining about a niche use case.
The majority of users won’t notice a slowdown of even 50% on an SSD. It won’t effect game performance, your network will bottleneck before your SSD in any internet download, most users don’t interact with extremely large sets of data which is needed asap on the regular.
You’re essentially only going to have a problem, in daily use for the average user, in (un)packing large sets of data, or moving large sets of data between drives. Things most people don’t do regularly.
So a slight alteration to my question, how exactly does this negatively affect most users in daily usage.

SSDs, unless you buy a specifically encryption supported drive, are not encrypted. If it doesn't indicate SED, SED non-FIPS or a FIPS certification level, the drive doesn't have an encryption circuit.

I don’t think you understood my comment. I said nothing about adding more encryption, in fact I said the opposite.

No, they don't.
Sure, but 20-40% slower? That points to something being poorly optimised.
Yes, that's what happens when there's no hardware acceleration and it fails back to software.
They should still be using the CPU's built-in AES hardware acceleration, yes? It seems they have good reason not to trust the SSD to handle the encryption but that doesn't mean it has to be entirely implemented in software. CPU-accelerated AES shouldn't be that much slower.
This is the same as all other solutions.
