Would the SD cards be mainly Read or Read/Write? I think the difference would be important as to reliability/long term usability. To be honest I am just now starting to use SD cards more and for me they are mainly a Read with occasional Writes so I would think unlike spinning drives they will last longer.

We have 14 field offices where we have servers. During our recent, and ongoing, migration from Novell/Groupwise, to AD/Exchange, we put VM hosts at those sites. We have them booting off SD cards, with hot spares in the case, and using the internal drives as the storage. Works great, no problems, so far.

On our older boxes we've booted from the two RAID 1 drives and used the spare drive storage to hold ISO images for Server 2008 R2, etc. Now we're considering just booting from an internal SD card and eliminating the hard drives altogether. The ISOs would move to the SAN but only a single copy of each. And there'd be fewer spinning drives in the rack with the benefit of less noise and heat in the data center. Have SD cards proven to be any more/less reliable than spinning hard drives? Any performance concerns with VMware on either? Given a choice of SD only or a RAID 1 HD boot config, which would you select?
