Adding More Storage to UNAS Pro

[@MrTimTech2022]

Hey Willie, great video and looks like they've done a good job too with the interface and settings, personally I would have just liked to select my own RAID level but the again they've done it that way to make it easier for non technical people to setup, for those not that familiar with RAID, I guess so it does make sense. It will be good to see how they perform in day to day operation, when you get up to that stage of having it fully setup and ready for use. Be great to see a closing off video seeing it in final operation when you get all the drives setup, formatted and files on their being read and written.

Can you only have 1 pool on this?

Have you tried SAS drives in it? I can’t find anything that says SATA only.

I wonder. i am starting my UNAS off with 5x 4TB drives, and would like to upgrade them to 7x 8TB across the board on basic protection. I know if i install an 8TB alongside a 4TB, it'll only use 4 of the 8. But if I upgrade ALL the 4TB to 8TB, will it automatically unlock the other half of the 8TB drives to give me full capacity? I'm not super familiar with RAID, hence why i'm getting this lol

With RAID 10 (it's actually not RAID Ten, it's RAID One Zero or 1+0). With 6 drives, it will mirror (RAID 1) each set of 2, then stripe (RAID 0) across the 3 sets. You can lose any 1 drive in each of the sets and still have your data. So, if you lose the correct drives, you can lose up to 3. The main issue is that it requires 1/2 your space for redundancy, just as with RAID 1. With RAID 6, you could lose any 2 drives and still have your data. This requires a minimum of 4 drives, but you can have many more. You lose the space of 2 drives to redundancy. With RAID 5, you can lose any 1 drive and still have your data. This requires a minimum of 3 drives, but again, you can have many more. You lose the space of 1 drive to redundancy. There is also a RAID 01 (0+1). With that, if you had 6 drives, it would stripe (RAID 0) across 3 drives then mirror (RAID 1) that to the other 3 drives. You could lose any number of drives in one of the sets of 3 and continue to run on the other set of 3. Just like RAID 1 and RAID 10, you lose 1/2 your drive space to redundancy.

I wish they would add raid 6 to this. Raid 5 is not enough protection for bigger drives.

[@wmcomprev]

There's not much difference between RAID 6 and RAID 5 + a hot spare as long as you don't lose 2 drives before the hot spare can be brought online.

[@badgett83]

@ I have a nas now and lost 2 drives. Lost the first drive… and while it was rebuilding… I was about 80% done and lost the second drive. So yes…. Raid 6 saved my bacon. A raid 5+hot spare and I would have lost 20 years worth of work.
