comment Fastest Linux Filesystem on Shingled Disks
BTW, I am doing more thorough benchmarks. Should be ready in a month.

comment Fastest Linux Filesystem on Shingled Disks
@qasdfdsaq Thanks, I removed reference to CoW. I understand that at the level of the platter shingled drives are much slower for random writes than PMR, but that the SMR can emulate faster writes due to the cache; a PMR drive + cache would presumably be faster again. Do you have a reference for the 30GB figure? There doesn't seem to be an official number, e.g. on the Seagate technical specifications. Also, optimizing for shingled drives might be a similar problem to optimising RAID 5 arrays?

Compare to unshingled performance.

Given that I am limiting the FS to mainstream ones, it would probably have to be a Seagate style?

Not really. I will add more benchmarks as I do them to answer such questions, but someone with more benchmark experience could probably do a better job than me. Hopefully this is enough to give a rough idea whether it might be worth considering switching from ext4 on a SMR disk.

comment DVD/CD burning .zip: is it more reliable, faster, longer lasting to burn a zip of files rather than the files as a folder?
In a zip, files are compressed independently, so a flipped bit will normally corrupt only a single file. I wrote a script to test this: github.com/gmatht/joshell/blob/master/scripts/…

OK, I have added some details on how you might use xrandr to test resolution support on a GPU.

How did you get xrandr to show you the maximum resolution of your graphics card? It only shows me the maximum resolution of my monitor.
