Duh on my part. Sorry for the double post. I receive the batch digest and sent this message with the wrong subject.

Does this blanket statement cover ATA RAID controllers as well? Is this a performance issue or a data loss issue? I have over 10 test/development servers in-house that use single IDE hard drives that run databases on ReiserFS and EXT3 without any data loss. Performance is sufficient for their purpose. I also have over 40 servers in the field using either Dell(LSI) or 3ware PATA/SATA hardware RAID controllers (RAID5) running databases on ReiserFS and EXT3 filesystems. Many have seen close to two years of service and they have been problem free. Our customers are very pleased with the performance of the database access. People, including myself, come here to learn and when we can, add our experiences. Please be careful with your opinions, there are a lot of people viewing this list because they assume you have the answers based on experience. It would help a viewer of this thread to see a reference or two to substantiate your claim. If I have done a customer a disservice in the configuration of their servers, I want to remedy it immediately. Thanks, Frank
