The default IDE device emulated is a PIIX3, which supports up to four
IDE devices. Since NAS4Free is based on FreeBSD, I think you could
recompile a custom kernel with the PVHVM config file, in order to use PV
drivers for IO, which will improve performance and allow you to use more
than 4 disk devices. This blog post may be of help:
