Plus, they were the first to come out with PCIe Gen 4. Configure SuperDuper (Or TimeMacine) to clone your main drive to “Backup”. (Re-)silvering is the ZFS equivalent of rebuilding a RAID array, but as ZFS has complete knowledge of how storage is being used, and which data is reliable, it can often avoid the full rebuild that other RAID rebuilds require, and copy and verify only the minimum data needed to restore the array to full operation.
