SSD in a Toshiba Satellite Laptop

So the old magnetic drive in my Toshiba laptop is toast; more and more errors every day. While the laptop is currently running Ubuntu I am intending on installing a SSD and FreeBSD running emulators/virtualbox-ose. Then I will install FreeBSD and Linux guests on virtualbox.

Anything I should be aware of when it comes to FreeBSD, solid state drives, especially in a Toshiba laptop environment running virtualbox. Virtual box is optional, but I do want to try it.

Laptop details:
8GB ram
Satellite S50-A
Yeah I will be using UFS. I already ordered a SSD. :D

Where do I read about trim, or leaving a few gigabytes of unallocated space at the end of the drive ?
  -t         Turn on the TRIM enable flag.  If enabled,    and if the underlying
         device supports the BIO_DELETE command, the file system will send
         a delete request to the underlying    device for each    freed block.
         The trim enable flag is typically set when    the underlying device
         uses flash-memory as the device can use the delete    command    to
         pre-zero or at least avoid    copying    blocks that have been deleted.

-t    enable | disable
         Turn on/off the TRIM enable flag. ...
Virtual box is optional, but I do want to try it.
If your CPU supports it also have a look at bhyve(8), FreeBSD's very own hyper-visor. Setting it up by hand is a little tricky but sysutils/vm-bhyve makes it really simple to use.

Due to family pressure I ended up putting Ubuntu Gnome back on it. But that just said I will be soon buying me a new machine to use in a power desktop role, and it will be FreeBSD for sure. I'll review byyve, thanks SirDice.
