Other Is there a quick method to detect whether disk is SSD

[redriver]

As I know, Linux has lsscsi which can tell whether the disk is SSD. What is the corresponding command on FreeBSD? or is there an alternative command which indicates whether the disk is SSD or not?

How about camcontrol devlist? If you have sysutils/smartmontools installed, smartctl -a /dev/ada0 (with your device) should tell you.

Depends on why you are trying to identify an SSD.
Is it to see if it has non-rotating media, so is fast?

% camcontrol identify ada0 | grep rotating
media RPM  non-rotating

Is it to see if it supports TRIM?

% camcontrol identify ada0 | grep DSM/TRIM
Data Set Management (DSM/TRIM) yes
