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
	512         	# sectorsize
	320072933376	# mediasize in bytes (298G)
	625142448   	# mediasize in sectors
	4096        	# stripesize
	0           	# stripeoffset
	620181      	# Cylinders according to firmware.
	16          	# Heads according to firmware.
	63          	# Sectors according to firmware.
	HGST HTS545032A7E680	# Disk descr.
	TMA45DZG06UX8R	# Disk ident.
	No          	# TRIM/UNMAP support
	5400        	# Rotation rate in RPM
	Not_Zoned   	# Zone Mode

These are are lines of top's header (poudriere is building one of the ports I think
might be problematic):

CPU: 32.8% user,  4.8% nice,  8.3% system,  0.5% interrupt, 53.5% idle
