So basically, the naming of the device is only important at the time of creating the array (as that defines the layout). As soon as I create the array, mdadm puts it's own metadata on the drive so it can identify them afterwards? That sounds very good indeed. Now, onto the topic of PCIe adapter. I was looking at this: http://www.cclonline.com/product/42541/PEXSAT32/IDE-SATA-SCSI-Cards/StarTech-2-Port-SATA-6-Gbps-PCI-Express-SATA-Controller-Card/CNT1075/ Is that a bad model? Seems a little on the cheap side? Can anyone suggest a good model? Many Thanks for all the help
