It is indeed a commercial product. Check with FSMLabs for information
on it. Note that in RTCoreBSD, all of FreeBSD runs as a client task
of their proprietary real-time kernel

Many commercial RTOS use BSD networking code. Like other UNIX-ish
systems, BSD is not suitable for hard-real-time applications. On the
other hand, it works quite well for embedded applications focused on
efficiency rather than controlling latency.
Not knowing your requirements, there's little more guidance we can
give you. However, there is quite a bit of material you may find
useful. Have you looked at the FreeBSD Documentation article on
"FreeBSD and Solid State Devices"?
Good luck.
