It depends on your controller, but hardaware raid should anyway give you better performance. Beside, maybe 24 disks are pretty a lot, but which is the expectation to burst a second disk, before you change the first one?
Yes, the failure of a 2nd disk while a degraded array is being rebuilt.
And which is the expectation to burst a second disk before you can change the first one over a bunch of six?
The array will have hot spares, so when a disk fails, it will automatically pick a spare from a set and start rebuilding. I have no idea of the actual probability of a 2nd drive failing during the rebuild, but the more drives the higher the risk.
I would go with 2 raid5 hw-array.
