While sas is faster, the difference is moot if you have even a modest nvme cache.
I don’t know if it’s especially that much more reliable, especially I would take new SATA over second hand sas any day.
The hardware raid means everything is locked together, you lose a controller, you have to find a compatible controller. Lose a disk, you have to match pretty closely the previous disk. JBOD would be my strong recommendation for home usage where you need the flexibility in event of failure.






Hardware raid limits your flexibility, of any part fails, you probably have to closely match the part in replacement.
Performance wise, there’s not much to recommend them. Once upon a time the xor calculations weighed on CPU enough to matter. But cpus far outpaced storage throughput and now it’s a rounding error. They continued some performance edge by battery backed ram, but now you can have nvme as a cache. In random access, it can actually be a lability as it collapses all the drive command queues into one.
The biggest advantage is simplifying booting from such storage, but that can be handled in other ways that I wouldn’t care about that.
