RAID: hardware recommendation requested

Hi everyone: I'd like to upgrade my storage to a 2 bay RAID (6TB each bay) setup to store RAW files and act as a backup. I'm a serious amateur, 79/Z lenses, about 77,000 images, about 2TB of storage required, I've attached a couple of recent images for fun (not relevent to this inquiry).  I've seen quite a few hardware options from Synology, Sandisk, WD, etc and read a bunch of reviews but hoped that some members here might have some real world experience and could recommend a brand/model that is fast and reliable. I'l less price sentive I was good, not cheap. Thanks in advance for any help you might to offer. Colin
