Synology DS920+
0 TB
Question about Synology DS920+
Hello Together I have purchased a Synology NAS 920+. I bought it with 4x6TB hard drives. I currently have it configured as Raid 1. I currently only need about 1.5TB. I bought it used (2 months old) with 4x6TB. Now I still have 2x6 TB "left over". My question: Should I just leave these 2 "remaining" hard drives inside? Or take them home and store them somewhere? I don't need them at all at the moment because 2x6 TB as Raid 1 are easily enough for me. Unfortunately, I haven't found much useful information on the internet. Many thanks for your input! Regards Desmond :)
Hi Desmond.
I would install all the disks, then consumer them all evenly and participate in the Storj project. If it's fun to play with docker and with the crypto world a bit. Link: https://www.storj.io/node
RAID is not a backup. Use USB or cloud to be safe from ransomware.
Do you already have a backup? Why do you need this NAS? As mentioned above, you could use the additional hard drives as a backup destination. However, this is not optimal if there is a problem with the NAS itself, where all the hard drives would be corrupted afterwards. If you already have a backup solution, you could use RAID 10 for higher security and performance. If you can read English, you can read https://www.baarf.dk/BAARF... to understand why RAID10 is actually better than RAID5.
If you assume that only 1 disk fails at a time, then RAID 1 with 2 disks is sufficient.
If you assume that 2 disks will fail at the same time, I would also go to SHR-2 and insert all 4 disks.
In any case, take care of a backup solution. You can also set up 3 disks with SHR and connect the 4th disk as an external backup (however, this would not be my favourite variant for the backup).
Or, has the backup problem already been solved?
An automatic backup of Raid 1 (HD 1+2) on HD 3 with versioning several times a week. Put HD 4 in an external enclosure and use it to make backups of HD 3.
Hi Desmond, even if the disks are unused in the DS, they are still running. This means they need power unnecessarily and get operating hours. You can also set up a disc as a hot standby to increase security. I hope this helps you. Greetings
What's wrong with doing RAID 1 on all 4 disks? It certainly provides the highest possible level of security (up to 3 defective disks without data loss). If you only make the raid over two and the stupid case occurs that both are defective, it looks even worse. You've already bought it anyway and the disks won't get any fresher from lying around.
