I have an old machine I'd like to turn into a WORM server, but I want it to be silent and would rather re-use a bunch of old memory cards than spend money on new storage.
All I could find was a device that put two MicrSD cards into a single SD card. This is even better.
I'd buy it if there was a USB version, since the computer I want to re-use only has USB ports.
So yeah, I'm very much interested in this device.
At least with the SSD, you only have one microcontroller doing god-knows-what to hide the horrific reality of flash storage, vs 10 SD card microcontrollers and one on the adapter board, which are all probably even worse.
As I have a lot of odd SD cards unused in drawers I would be more interested in these adapters if they exposed every card as its own drive so I could do ZFS, or if they did "real" raid.
WORM is a slightly less scary, but I still wouldn't trust them without being able to handle failure of 50% of the cards.
Don't get Kingston, like this one, they seem to break leaving half the thing inside the USB port way too often in my experience :

But for just $218 USD you can have a brand new 1 TB USB 3.1 Portable SSD that does sequential reads/writes at 400 megabytes per second.
Trying to write a terabyte at two or even ten megabytes per second would be excruciating.
As noted above, this would be WORM
But for just $218 USD
I'd rather spend $218 on my family and re-use the flash I have lying around instead of dumping it in a landfill.
Sony has let me down as well, their cards have either poor or no wear leveling and will die in a matter of weeks when used in a GoPro. Every single one I bought has died inside of a year.
The longest lived microSD card I currently have is from Lexar and I recently bought some Samsung cards to see how they'll do.
Lexar is a less-known brand, less likely to be used by counterfeiters.
tldr: it seems to work as advertised but he can't find a valid use case for it.
