Re: Booting off of RAID10 versus RAID1

["David Lethe" <david@santools.com>]

I know of several vendors that have linux-based NAS appliance vendors who do this. It is rock solid, as long as you don't use consumer-quality usb flash.  Check specs on flash memory for throughput and write cycles and ECC and choose accordingly. Also look into IDE mounted flash. It directly plugs into IDE plug on mobo, so it will be internal, and emulates an ide disk.

I've been wondering about booting grub/initrd from a flash USB stick (industrial 
quality if needed).
