I can certainly vouch for CalDigit.
I’ve purchased three arrays from them over the past two years – An HDPro for my personal system, and an HDPro and HDElement for other facilities where I worked. All have been great, reliable performers. Customer service has been stellar. Last time I was in L.A. I stopped by their facility in Placentia and they gave me a quick tour (and a cool tee shirt to boot!).
My HDPro has been a solid workhorse, with no problems whatsoever. CalDigit has ensured an upgrade path to HDPro owners by designing the HDPro as a modular system. When the HDPro 2 came out, owners of the original HDPro could easily upgrade their existing units by simply swapping out their old RAID controller module with the new model that is used in the HDPro 2. A simple plug-and-play upgrade that doubles performance for a reasonable price is almost unheard of in the word of video tech. Most companies just expect you to ditch the old product and buy a new one. CalDigit recently began offering a rackmount bracket kit for the HDPro as well, which transforms the tower form factor into a rackmountable configuration. The build quality of the rackmount kit is impressive, featuring very heavy-duty machined aluminum brackets that completely replace the stock handles.
CalDigit’s products epitomize smart, beautiful design and very high build quality, and in my experience their customer service has been fantastic.
