Which internal hardware RAID controllers will survive some future to come in your estimate. First of all my beloved 3ware finally seems to have passed away. After multiple acquisitions and becoming part of LSI and getting bought with LSI, it probably became non operational. Namely, the latest 3ware cards have ancient firmware. Neither of them supports 4kn drives. This speaks for itself for me. [Under new ownership] LSI, though still having new controllers released, and one of their MegaRAID controllers (at least) having support for 4kn drives, still may not last long (just my feeling, I'd like to hear yours). So, what RAID controllers will those of us who like to have hardware RAIDs use in some future to come?
IMHO, "Hardware" (really embedded firmware) RAID is for Windows servers, since MS Windows has awful integrated software raid (aka 'dynamic disk', truly a mess). With Linux, I'd rather use LVM, with BSD, ZFS.
"Hardware RAID" can very well include a controller with dedicated parity processing, battery/flash backed write caching and other tangible benefits.
