I’m using version 9 for this guide, so if you’re reading this far in the future and a new version is out that you can’t get working.

This probably works on the EX490 and earlier versions of the Media Smart server like the EX480 and EX485, but you need to test it. The main advantage of using a USB over a HDD for a boot drive is that it keeps those precious caddies empty for your data drives.This is really great to do, I was happy to find it was incredibly simple to get this all up and running. There is no point in using SSD's or anything larger in capacity. (FreeNAS saves a mirror of every version you have installed when you upgrade for easy rollbacks. Even then you could just delete the old revisions of FreeNAS off it and open up space. 32G USB2 drives are super cheap and it will just give you plenty of room for years to come. After that the USB does nothing.Īs for the size I would honestly recommend 32G at the minimum.

Once the system boots, which takes about 5 mins I would guess, everything gets loaded into RAM and then the USB just sits there. You can even run them mirrored if you get two, it's an easy feature to enable. I currently run my FreeNAS on an R710 via the internal USB with a Sandisk Cruzer Fit 32G. Because of this boot times are not important. This thing is supposed to be booted and never turned off unless for updates. Just remember that this is a server you are building.
