The subtle point here is that whether a drive has been out long enough to have a stable firmware is very much a component of its overall quality and reliability--regardless of whether the drive works fine in any one system or not. The odds of you'll get a RAID compability breaking firmware change in the first few months a drive is on the market are painfully high. You don't have to defend that it was the right decision for you, I was just uncomfortable with the way you were extrapolating your experience to provide a larger rule of thumb. Allocated hot spares and cold spares on the shelf are both important, but for most people those should be a safety net on top of making the safest hardware choice, rather than as a way to allow taking excessive risks in what you buy. -- * Greg Smith gsmith@gregsmith.com http://www.gregsmith.com Baltimore, MD
