I'm considering a FreeNAS installation for a client. FreeNAS is *really*
built around the idea of separating it's software from the data, to the
point that it needs a dedicated "disk" for itself. The FreeNAS folks were
really thinking of this as being a USB key, since they only need 2G. I
don't really like the idea of using a USB key for this, because:
1) it sticks out of the machine somewhere where it can get
bumped/broken/etc. (Yes, I could arrange to have it on an internal or a new
USB add-on card that has an internal slot, but that seems like a bother).
2) I'm generally not thrilled about a production machine's life and death
hanging on the reliability of a USB key.
What I would really like to use is a CD-ROM, but the media needs to be
read-write, so that's out. There will be a small but steady amount of
writing to the media for logs, temp files, etc., so it's not static by any
means.
I'm considering using an CF card instead of a USB key, but I am wondering if
the underlying hardware is really any different. Is it just a USB key in a
different package? Do any of you folks have thoughts about reliability of
these various media choices or others I haven't considered?
