Storagereview and AnandTech both put the VRaptor around average read/write speeds for a HDD. Faster RPMs really only help with latency.
Are these servers meant to stay on, or do they get shut down at night?
If they get shut down every night I would suggest just getting a small boot SSD for each machine if you can't figure out exactly what is causing the boot hangs. I think you're right that it is a conflict with the RAID card but unfortunately for that I have no idea how to help.
Having an SSD for boot on the board would actually eliminate the need for a painful install process as well as greatly reducing boot times and system access latency.
Thank you for the quick response. I've attached an image of the speeds. I used ATTO Benchmark which displays sequential speeds right?
The servers stay on 24/7 so we haven't worried too much. It's mostly been the installation of Hyper-V and clustering that has required many restarts. I'll continue trying to resolve the hang and make a recommendation for a boot drive. Thanks.
