HP P410 controller is by no means close and by no means comparable with
any of Areca RAID controllers. If I'm reading the description correctly,
P410 supports: RAID 0, RAID 1, RAID 10


you need the optional cache module and the feature option for the p410 to support raid 5/6.   I always ordered my HPs with the larger cache and the 'flash backed writeback cache' option rather than battery backed (flash backed uses supercaps which last approximately forever, while raid battery backup tends to fail in 3-4 years).

p410 is already quite obsolete, the gen8 servers I ordered a couple years ago came with P420, I don't doubt thats been replaced in gen9 stuff.

my personal preference is to get rid of the raid cards entirely and use plain SAS HBA's with OS native raid support, for everything but dedicated windows servers.
