I have a test system at work nearly identical to one at home. i have sundays at work i can mess with this. last week i had 2 of the same flash drives off-brand transcend 4gb. one with installer on back usb, one in the usb header on the mobo. it is in a SuperMicro 12-bay case, redundant power supplies, and SUPERMICRO MBD-X9SCL-O , with a XEON and 32gb.
last week i seemed to have gotten the installer written to the flash drive correctly ( i think), but it would get to where do you want to install, picked other flash drive, go to try to make partitions and fail.
Today, i bought a sandisk flash drive hoping to use that as boot device. cannot seem to get the installation media right. Tried both Rufus and unetbootin to burn the iso to flash drive. even burned a cd, and used a usb cd-rom to to to install from there. the cd just gave read errors till it quit. time with image after using unetbootin, just sat at a blinky cursor. with rufus, get to the grub menu 2.3a http://doc.freenas.org/9.3/freenas_install.html but then it drops down to some maintenance shell, like it cannot read the flash drive.
