I don't think it is a SSD (it has cylinders, sectors etc.).
If you can tell me a way to check it I will be glad to do it.
This is the output of diskinfo -v /dev/ada0 in case it answers the question=
:
/dev/ada0
=09512 =09# sectorsize
=09320072933376=09# mediasize in bytes (298G)
=09625142448 =09# mediasize in sectors
=094096 =09# stripesize
=090 =09# stripeoffset
=09620181 =09# Cylinders according to firmware.
=0916 =09# Heads according to firmware.
=0963 =09# Sectors according to firmware.
=09HGST HTS545032A7E680=09# Disk descr.
=09TMA45DZG06UX8R=09# Disk ident.
=09No =09# TRIM/UNMAP support
=095400 =09# Rotation rate in RPM
=09Not_Zoned =09# Zone Mode
These are are lines of top's header (poudriere is building one of the ports=
I think
might be problematic):
