I wonder how this impacts LVMs, just setup a 2x512GB SSD LVM and plan to add another 500GB SSD to it soon.
But tbh as long as it beats HDD write speeds it’s probably good enough for the most part. Hard to properly test as my most recent large data transfer on it was with game files and many tiny files are always going to be slower.
It affects them just as much, since LVMs still run on the hardware, so anything on hardware layer will affect the LVM too.
First, this is mostly only for write speeds. Read speeds aren’t really affected by this.
So if your 2x512GB are close to full, these will be much slower. If you add a third, that one will be fast. So you’ll still be able to write at about the speed of one drive.
If you balance the load (which, afaik LVM doesn’t proactively do when you add a new drive), you can get your total speed up by a lot.

What about something like LVM cache? Would it be worth setting up an X% empty partition on the drive, just for empty space reasons?
