I have been reading a lot of warnings about Raid-6 becoming less and less safe to use due to the storage amount per disk as well as array sizes increasing.
What are the best practice limits/when does it make sense to take the economical hit of using Raid-10 instead? (at which size)
We are considering these disk combinations: Hotstorage:
- 10x4TB SSDs
Coldstorage:
- 10x10TB HDDs
- 15x10TB HDDs
- 12x12TB HDDs
Raid-6 would save us a lot of money, yet is it safe to use at those sizes in terms of normal failures and rebuild times.
Thanks
