I'd go with SD. VMware doesn't need swap for itself, so won't page to the SD - that means that pretty much the only time the SD get written is when you upgrade/patch VMware itself, so reliability isn't much of an issue.
It'll make your hosts a bit cheaper, too, since there's no need for a RAID card, nor spinning, rust-covered glass - all of those also eat more electricity than the SD.
