All of my hypervisor machines and guest xen PV and HVM machines are now on fast SSDs... The on-site backup server is still RAID10 HDD based for $/GB reasons, it doesn't need fast throughput, and its twin offsite machine is also HDD based.
Interestingly for many 'enterprise' applications you don't need that much disk space at all, if things are set up right. So you can use expensive and high quality SSDs. Example, the Sugar/SuiteCRM VM has 20GB of disk total allocated to it and is using maybe 4GB of that, of which 85% is the operating system itself. I remember buying a 240GB Intel SSD for $1/GB three years ago for my laptop, and thinking that was great. Now a Samsung 850 Evo 1TB is nearly the same price.
