Backing up your devices to NAS using Time Machine No performance penalty from the second redundant drive and you still have protection the trade-off is you get a big performance penalty when the hot spare is activated (while it rebuilds) and thereвЂ™s still a risk of the array failing if a second drive fails while the array is rebuilding. You may consider setting it up with SHR1 and a hot spare. No penalty from simultaneous use as long as each use is on a different volume.One drive needs to fail before there is a risk of data loss.Slight performance penalty in situations where there is significant use from two sources.Two drives need to fail before there is a risk of data loss.The only advantage you would gain would be less loss of data if an array fails, but at the cost of a higher risk of array failure. LetвЂ™s take an example a NAS with 4 x 6TBb drives.

The advantage to creating multiple volumes comes when you are using different size drives, want different levels of redundancy, or have significantly different uses. That being said, in this case you want to just make one, and then create shares to logically organize things. You can use the Synology RAID calculatorВ to help determine how you want to set up volumes. ItвЂ™s important that before you start you understand the concept of volumes on Synology Diskstations, because thatвЂ™s the first thing you will need to set up before you set up Time Machine backups.
