I had a feeling using a cheap $7 flash drive as the boot OS might be a bad idea. Turns out it was. The drive started throwing errors after about a month and a half of running pfSense for my network. I didn’t want to go mechanical HDD for a 24x7 low power box so I decided on a OCZ Onyx 32 GB SSD. More than enough size and speed for how I am using it. Hopefully this is the last hiccup with this machine and I can now get into some more advanced features of pfSense.
