Many people ,including myself, prefer to install FreeNAS on a USB flash drive ,to save internal HDD drive slots,and in the former version doing this is quite OK,as it treat the boot media as almost read-only,
But in FreeNAS 9.3+ the boot drive was switched from UFS to ZFS,so it writes to the boot media a lot more
and the offical documentations says
but nowaday almost all the USB flash drives on the market are based on the TLC(Triple-Level-Cell) Flash chips.
This kind of flash chip is cheap and wear out very fast(most of 'em can only be rewritten(P/E) for about 300-500 times )
So, besides using 2 or more drives for a mirrored syspool(Though TLC flash drives is very cheap and affordable for a mirrored configuration,I really don't want to worry about a 'DEGRADED' syspool all day long),Is there any USB flash drive models recommended?
I've tested most famous brands in local market - Sandisk,Lexar,Kingston,Toshiba and PNY,all of 'em are TLC.

- when using a USB stick, it is recommended to use a name brand USB stick as ZFS will quickly find errors on cheap, not well made sticks.
