A RAID controller with battery backed or flash backed cache could make this less of an issue. Use single disks rather than an array. Disable any cache directly on the disks since that would defeat the RAID controller cache. You wouldn't need the latest RAID controllers so an older Dell or HP card from ebay or the like would do. Make absolute certain that any controller you have includes the battery backed cache and the larger the cache the better 512 or more. </div>
