Jim,
Sorry for the delayed response; I've been too busy for my own good.
First, I don't see the point in paying the premium for a third-party "ruggedized" case if you're using an SSD. Just buy an external SSD in a stock factory case; e.g..:
It's tiny, fast & affordable though with limited capacity.
For a larger-capacity application I still use spinning hard drives. Unfortunately this is a dying breed and the state of the art is several years old; the best I can find is the "Hitachi" 2.5" 7200rpm drive:
If you put a pair of them in a small case with a hardware RAID 0 controller, you can get an honest 250MB/sec (2 Gbits/sec) sustained write speed for large file sizes.:
I use a StarTech enclosure but there are a bunch of different brandings that all look alike; e.g.:
A couple of notes if you go this route:
1) For spinning hard drives, the enclosure must have a fan. Don't accept those "passive cooling" enclosures; your drives will die young.
2) Check your drive's SMART diagnostics when it arrives to see its "mileage"; there are lots of horror stories about used drives being sold as new.
3) I was shocked to find in my testing that some hard drive enclosures CAN operate when powered only via their USB connection, but have HIGHER throughput when powered externally via a "wall wart".
4) That "Hitachi" 1GB drive (above) is now the largest-capacity 2.5" drive available that still uses the trusty old "PMR" ("Parallel Magnetic Recording") technology. Don't be fooled into buying the larger-capacity 2.5" drives which all use the newer "SMR" ("Shingled Magnetic Recording") technology which is fast when newly formatted but horribly slow when re-writing over previously-written sectors. If you don't know these terms, Google is your friend.
5) Test, test, and test some more. Don't trust manufacturers' assurances. They aren't working in the field the way that we are.
Good luck!

I need to buy four or five 2-4GB drives for backing up camera cards in the field. Not for big jobs where there's a DIT or anything. Just for making a couple copies of everything during lunch or at the Ritz/yurt at the end of the day. Not for editing. But want something reliably transportable...
I'm leaning towards something from CalDigit of Glyph. For example:
Glyph Technologies Blackbox Plus
https://www.glyphtech.com/product/blackbox-plus
CalDigit Tuff
https://www.caldigit.com/tuff
I have a decent grip on the field issues. But have you all bumped into problems had positive experiences with certain brands/models?
Thanks,
Jim
