Planning to install ubuntu server on a small, fan less PC which has a 64 GB eMMC storage (no other storage possible). I plan to use it as a VPN server applicance (it will have 2 ethernet, one wired and one wireless ports).

I was wondering if, for this application, the emmc storage will have adequate performance, esp when installing and updating software. I might also install either the access manager application from or the web based administration interface suggested on ubuntu server documentation page.
