Is Apple RAID Card compatible with El Capitan

I'm hoping someone here can save me the trouble of finding this out "the hard way" ;-)

I have a 2010 Mac Pro with an Apple RAID Card that is supporting a RAID 5 of 4 x 2TB disks running OS X 10.10 Yosemite. My boot drive is an OWC Accelsior E2 SSD (in a PCIe slot) so I don't need RAID support to boot, but I need it to show up once booted.

I've updated my MacBook Pro to 10.11 El Capitan and noticed that the Disk Utility no longer supports RAID! (what was Apple thinking???) What does this imply?

So my question is:

If I upgrade my 2010 Mac Pro to OS X 10.11 El Capitan, will my Apple RAID Card continue to work? i.e., is it still supported?

Thanks in advance for any insight you can provide,

Well... it came with the Mac Pro when I bought it and it's working so who am I to fix something that's not broken. ;-) I do have an external RAID 5 that is connected via eSATA but I get your point.

Actually, just last month the battery failed on my Apple RAID Card and I'm now contemplating spending $130USD on a new battery which I guess begs the question, would that money be better spent buying a new RAID card that doesn't have the 2TB per disk limit of the existing card.

Would any of those cards be able to use my internal drives? I was trying to decide what to do with the 4 internal drive bays so I thought that making a RAID 5 using the existing Apple RAID Card would be the best use of them rather than 4 independent drives. Any recommendations?

Thanks for your feedback. I'll do an upgrade to El Capitan this weekend and see how it goes.

yes, ANY of the RAID boxes (Highpoint, etc.) will be able to use your drives. HOWEVER - I am guessing that the raid formatting is different, so you will lose you data on the drives (so you need to back it up somewhere). When you switch between an Areca, ATTO, Highpoint, and LSI Logic card, all of these companies raid config is incompatible with each other, so you are always starting from ground zero.
