Thanks...
Been using Linux since Redhat version 9, and Fedora
Core 1 thru 34 and 35 on machines. Had Unixware before
that.
Use standard partition setup.
Will have to look at info on fstrim?
On my notebook with SSD drive
fstrim -v -A
/DATA: 22.4 GiB (24029523968 bytes) trimmed on /dev/sda9
/home: 436.6 GiB (468820439040 bytes) trimmed on /dev/sda8
/boot: 651.2 MiB (682827776 bytes) trimmed on /dev/sda5
/: 17.7 GiB (18981560320 bytes) trimmed on /dev/sda7
Had SSD in this one for a while. Recall something on
fstrim??
New machine showed this.
fstrim -v -A
/home: 741.1 GiB (795723341824 bytes) trimmed on /dev/sda5
/boot: 612.2 MiB (641925120 bytes) trimmed on /dev/sda1
/: 37.4 GiB (40122470400 bytes) trimmed on /dev/sda3

Haven't used BTRFS on a system yet.
Is there a service or what to run the fstrim?
Tried it on two other machines that still have regular
disks, and command shows no output, so guess it doesn't
apply to regular disks?
Thanks again for the quick response.
More stuff to look into.
