These days, CD images are a tiny proportion of typical hard disk
capacities. Every terabyte of disk can hold over a thousand ISOs, and
that's assuming they're using the whole disc (~760MB). Several
thousand, if they're only part-full images.
But the time factor is considerable. Especially if you then have to
boot up a VM or something to test it.
