Most stable RAID

For large terabyte hard drives, raid five is not recommended.

This would be for an 8 drive 3tb per drive system.

So, we would be between RAID 1, 6, or 10.

RAID 1 would just be mirrored drives. You could combine these drives into one large drive with windows.

This would mean you lose set of mirrored drives, and you are out of luck. But you could lose up to four and still be ok. Or you could lose two and be out of luck.

RAID 10 would basically be the same thing.

RAID 6 would allow you to lose two hard drives and still be ok.

So, it comes down to where and how the drives are likely to fail. A mechanical hard drive fail is unlikely, but could happen. It would be more likely for write errors and bad sectors or raid controller error to cause a drive problem I believe.

And because of the use of parity, I think these errors are worse for a RAID 6.

Size of the drive does not matter. Either way you go, the size will be ok.

So, what is the safest way to build this array?

RAID 6 or 10?

RAID 10 would give you 12 tb of storage. The Raid 6 would give you 15 tb even with one drive held back as a hot spare.

But the 12 tb would be enough. I would't have the hot spare in a 10 build however.

So, what says the tech masters?
