I have a lot of computers - they are all linux based but one which is windows 10. From 96 till around 05 i used freebsd which required non ide drives. Then apple hired Jordan to do their micro-kernel (using freebsd).
I'd like to upgrade my windows 10 box to windows 11 but i need to make a recovery disk first which i will one day. The hardware supports tp whatever for secure boot but since i started with windows 7 (or was it 3.1) and upgraded through 10 the boot drive is currently non-secure which windows 11 requires. To be honest 7 was the best and all this transition is just bullcrap by a bullcrappy company but patches are mandatory in these days even if the machine is only on when i play games (i use it like a ps4 but kb/m only).
For linux i run zfs so i use ubuntu since i got tired of building my own kernel (which i did before ubuntu provided zfs with the install). zfs is the best - when we made a raid system @ work it was pretty neat since the raid was distributed across a cluster and as long as P+1 disks didn't fail we could keep serving data if machines crashed or disk died (and disk died a bit more often than they should but when you have several many 10's of thousand disks a few will die every couple of days. Sadly we couldn't take any of the disks home for personal usage
