I bought my first NAS the DS920+ and am worried about getting locked into Synology. Couple questions:
I imagine a controller crash may result in the last few writes being interrupted and potentially leave the storage pool in a corrupted (but hopefully recoverable) state. I'm not worried about recovering those partial writes - only about recovering whatever was written successfully earlier.
And yes I know that a NAS should be backed up too but for the purposes of this discussion please assume no backup exists.
- If my NAS crashes 10 years down the road - not the drives but if the controller hardware fried itself - would I need another Synology NAS to recover my data? Can I buy a non-Synology NAS (perhaps a 6 bay QNAP) and put my drives in the same order and expect to be able to access my data on the storage pool/volumes?
- If I need another Synology NAS, would it have to be similar to the DS920+? Worried that 10 years down it may not exist and support for the 920 long gone...
- If I use RAID 5 instead of SHR-1 will recovery be potentially easier in a controller crash scenario?
