UPDATE: I haven’t been keeping it up to date so deprecated it - if you find something like this useful moan at microsoft and get them to implement it!
I keep having to refer to the virtual machine size page and the disks pricing page to work out how best to stripe disks for whichever type of virtual maching in Azure to work out what sort of throughput we can get so I thought I would save myself some ink and automate it, hopefully someone else finds this useful.
