This hasn't been my experience… I run a production company that makes mostly commercials, branded content, etc. Almost every project shoots on one of the Arri Alexa variants. We deploy mirrored pairs of drives to every shoot. When possible, 2-bay RAIDs (frequently OWC Mercury Elite Pro Dual actually!), but very frequently shuttle drives like Ruggeds as well. Sometimes the DIT (basically data manager responsible for downloading media) is working off a laptop, sometimes they don't have access to consistent power and can really benefit from bus power, and sometimes production needs to travel and don't want to pack multiple huge raids. As skeptical as I was of LaCie after their dark days in early 00s, Ruggeds have always served us well and I'm excited for these new ones -- though I sadly don't think the SD card slot will be very useful for us — maybe CFast ; )
No, raw media does not go to the cloud (for many reasons), and cards are very infrequently being dumped to SSDs -- the huge amounts of data generated per day and the disposable nature of on-set drives that need to be sent to several post production partners and frequently delivered to clients most often precludes that option b/c of the cost. Every so often you'll hire a particularly well kitted DIT that has a SSD RAID built into their cart, but this is just for getting media off of cards quickly, when then gets transferred to spinning drives to deliver to production at the end of the day.
Can't speak for serialized content where they have the luxury of working with a single team for months or years at a time and have consistent access to and control over locations -- maybe rugged drives are irrelevant in that world, but certainly not in commercial production!
