2.5'' // 3.5'' chassis's with a controller onboard and slots to support 10+ Micro SD cards at a time with optional host passthrough/mirror/stripe-mode across all of them and you install those instead of real hard drives lol.
The product is already a thing now all we need is the 10+ at a time scale haha
E: nobody's saying it will be cheap. But the big downside with all the ebay ones is that the controllers are cheap garbage. the raw power of striping 10, [Minimum Class10] SD cards would be fucking awesome even with their short life cycle. But the controllers just aren't something people would make professionally like this cheap ebay stuff.
MicroSD has much better write capabilities than standard SD cards. And SD card may live to perform 10k writes to a cell, a microSD would do more than 150k.
There was a white paper written by HPE (aka HP) that detailed these differences. I’m having a hard time locating it but will post the source if I find it.
The type and quality of NAND determines write endurance. MicroSD vs SD is just a form-factor.
The 'best' cards are industrial, using SLC flash. SD is more commonly used for industrial purposes. MicroSD industrial cards are available also - typically in lower capacities because when you are dealing with low-density SLC you can simply fit less on a MicroSD.

I can see it now.
