I am looking to rent 6 of these servers: http://www.hetzner.de/en/hosting/produkte_rootserver/ex4s
As you can see, the hard drives aren't server grade and they break a lot.
I was wondering if it's a good idea to install a distribution of Linux inside a 64gb USB stick and use the 3TB IDE SATA disks as cache for the application.
My idea was to keep the base system still working if necessary. It's easier than running KVM or rescue systems once the predictable break of the drives will happen. I just need to facilitate the rescue system hassle.
