RE: Filesystem vs. Raw IO

Used them in a lab. works ok; plenty of speed. The good ones allow you to write to memory cache; and "ack" the oracle process; and then takes the cache to disk.. What little testing we did; I just put the online redo logs and archive redo's on them..

How about solid state disks? There was an article about US government buying

1TB solid state disk. I imagine that the speed of writing to that baby is not an order of magnitude larger then the speed of writing to memory.
