I’d like to replace the aging drives in the RAID 5 array with some modern enterprise drives and add in at least one hot spare. We have a cwrc learned through years of maintaining servers that drives born together tend to die together. You might be able to get a little more performance by rebuilding the array into RAID Looking for some advice on to how best improve fault sat and possibly disk performance in this oldish Dell PowerEdge Boiled down, it essentially provides Word and Excel documents to 20 people with maybe emails total per day.
