Thank you. I would advise everyone stay away from Akitio 4 bay enclosures if this feature matters (and it should matter).

Thanks for the Blink Light heads up. :-) Here is a screen shot. These numbers don't match the SNs on the physical hdds.

Yes RAID 1+0 is best for your requirement. You do not really need 7200 RPM drives. My impression is 5400 will last longer also. I recommend you ...

We cannot talk about specific future features yet. There would be an obvious benefit to converting, however. Thanks!!
