The new WordPress editor is a pain in the ass. Not easy to insert images from URLS, and then make them a link. I converted the image to HTML, and manually did it. Don’t feel like trying to find the right block.

Is it faster? Maybe, didn’t  run any benchmark. Luckily the Timeshift backup was good, so I didn’t have to try restoring my Restic backup. I wiped the SSD, using the secure erase in my bios.

Computer surgery is easy, if you lay the computer down. I had to remove both video cards, might of only needed to remove the Windows video card. I removed the other one first, couldn’t remember where the NVMe slot was. I just remembered it was under a video card. Would a heat sink even fit on it? With the video card right above it?

To get Manjaro to boot, I had to chroot into it, using manjaro-chroot is the fastest way, otherwise you have to manually mount everything it needs.
Ran “update-grub”, then “grub-install –efi-directory=/boot/efi”, make sure you mount the EFI partition into the mounted Manjaro install folder, under boot.

Booting UEFI on the SSD doesn’t work, you have to select the Manjaro boot option, I changed the bios boot order again. Otherwise I get a dead grub, unknown filesystem it says.

The write speed is supposed to be over 1,000. Better test with a bigger file.

Still slower then it should be. Should get at least 1,000 MB/s, unless it’s throttling hard.

You need over 20 GB to get 1,000 MB/s.

The advertised read speed is 2000 MB/s.

Speed of the buffer cache.
