Synology DS1515+, how to separate data

[Xcessiv]

Hello guys,

Just purchased a Synology DS1515+ (5-bays) with 5x 4TB HGST 7.2K RPM NAS drives.

I have around 1.5TB of documents and 3TB of movies, which will probably each double at the same pace over the next 3-4 years.

I really like the idea of RAID6, but don't thrust the fact that even my important documents will be spinning 24/7 to seed movie torrents

What would you do in my situation? I stick to the RAID6 configuration for all 5 drives together, or I separate them so that the documents remain in sleep mode when seeding movies. If I separate them, how to proceed and under what kind of configuration?

Thanks

RAID is no replacement for backups. You shouldn't trust anything important to RAID only. Use the eSATA or USB ports for backups of the NAS.

I won't comment on the illegal movie acquisition strategy...

I'll still stick to the 3-2-1 backup strategy, just trying to determine what is the best internal way to organize this array of independent disks based on this clear data separation.

So RAID6 + 3-2-1 backup is the way to go?

If your backup strategy is good, RAID 6 really won't benefit you. What RAID 6 is protecting you from is a second failure during a rebuild. You have to decide if the probability of a second disk failure during a rebuild is worth protecting against. This is why I say, if you believe your backup strategy is good then go with Synology SHR or RAID 5.
