Go with 10/15k RPM SAS, not Intel SSD or SATA if you want best
availability. Intel SSDs have had firmware issues since they came
out, I doubt we've seen the end of firmware changes on them.

If you want even higher availability go with a better provider,
this is a good cloud hosting provider which uses VMware and high
availability storage -

Looks like they have 4 locations in Europe, I haven't used them
myself but went through a presentation for them last year very
impressive, though they are pricey. If you have simple requirements
it's probably not bad though(will be a few times more $ than the
hosting provider your looking at, but hey you wanted fast, always
available, and safe, those aren't cheap). You can provision machines
yourself, manage a remote firewall, and load balancers from their
web UI.
