Disk devices in Windows are often enabled for write caching.  It seems to me that no performance trick is worth the price of losing data.  I was looking for a recommendation from progress about disabling the write caching behavior for any disk that hosts a progress database.  But I cannot find it.  Any pointers would be appreciated.  There are other generic recommendations outside the context of OE, but I feel like progress should also be stating this formally as well:

Taking it another step further, I'd really like to see a whitepaper about configuring storage for a database in a virtualized environment.   Here is a kb that makes a vague reference to write caching...  it seems like more elaboration would me helpful :
