Depends on the use-case really. I use raid (if any) for performance reasons, so I prefer hardware raid with a nice controller and some lots of spindles where flash is not an option. I would never implement this with a software raid solution for reasons.
- tomatocracy 8y agoLikewise. If it’s not offline, verified and off-site, it’s not a backup. Raid is useful for availability as well as performance though. Also while we’re discussing raid, the price/gb of a mirrored set of larger disks vs a raid 5/6/10 of smaller disks (for the same total capacity) is always worth checking - usually comes out in favour of mirrored pair in my experience which also has better performance (especially when resilvering) and resilience and lower energy costs.
