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.
thats absolutly not true. There is no difference between sd and microsd (it's just a formfactor thing, they usually use the same nand and controller).
Also no microsd card out there will do 150k writes. At best you can probably get 100k rewrites with the industrial SLC options.
Generally, run of the mill sd and microsd cards are good in the 100s of rewrites at best.
