I've heard a lot about people using Solid State Hard Drives with SharePoint lately. Have you seen a good benchmark published? I'd like to have some hard evidence before I spend a large amount of money on a very new technology like that.
Chris O'Brien (@ChrisO_Brien) pointed me to this series of articles today in a tweet: "This seems to be the authoritative SSD benchmarking - http://bit.ly/J1FNf"
If this isn't more information than you'll ever need to know, then I don't know what else you could need!
