Hi, By chance I found this statement in the Linux RAID Wiki: "Do NOT use [USB devices] as part of your array. They have a timeout/disconnect mechanism which interacts very badly with the raid code." [0] Could someone elaborate further on this? Does "interacts very badly" mean that there will be potential data loss / data corruption? Or does "very badly" just mean short, temporary performance issues / lags upon a disk failure?
