Which is the best caldigit raid for prores 4444 within my budget.

Hi all I hope someone can help me with this I am looking to buy a caldigit raid quite quickly to
playback prores 4444 footage (appox 2048x1152 lines) that was shot on a RED one camera. My current supplier has sold me a 12tb jbod with atto raid card but the noise being generated by this thing is unbelievable! I'm used to being around raids such as avid videoraids, unity, xserve etc but this thing is like having a vaccum cleaner next to you in the edit suite, my sound meter registered it at 70db.
Anyway I am based in the uk and looking to spend around 4-4.5 thousand pounds which seems to put me
in the price bracket for either a HDONE 8TB or a HDPRO 5TB. The extra capicity isn't essential (but it would be nice) if it means the raid can handle prores 4444 with no probs. Also I would like to be able to put the raid in the edit suite with me and still be able to cut dialogue!.
If thats not possible then I could possibly drill a hole in my wall and put the raid on the other side but if I do that aren't I restricted by mini sas cable length?. Is it possible to get a reliable mini sas connection with a cable longer than 1 metre?.

I would really apreciate any advise anyone can offer. :)
