Although I've had no issue with the single bay raidsonic/icybox stuff I've had I have seen reports that the multibay ones have had some issues.
As to the OP, I've been looking at the same type of thing recently (consolidate all my external into one jbod) and I've basically narrowed down to two options, the USB based option or a 4/5 bay NAS with JBOD support (qnap/synology etc).
First port of call for usb was obviously raidsonic/icybox but went off them due to seeing comments about failures/issues.
I've seen some positive comments about orico, sonnics (both basically look the same in all honesty, but sonnics slightly cheaper) and yottabox, which seem to have a range of options but tbh they're pretty 'new' brand. Having said that I'd put money on the internal hardware being the same on all of them (including raidsonic) and the only difference being the price, 'box' and branding lol
There's also silverstone who I've always had good experiences with although no 5 bay
