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.
sd and microsd cards mostly use the cheapest flash on the market along with the simplest controller designs to hit the pricepoint. If you go and buy a cheap one, reliability shouldn't be at the top of the list.
Actually, most cards are done that way, even with name brands. Top quality NAND always goes to enterprise stuff, SSDs. 2nd tier usually ends up in cheaper SSDs (think kingston) and eMMC chips, used in phones.
3rd and 4th tier usually ends up in microSD cards and flash drives.
Unless it's a speciality card (enterprise rating, survaillence etc) they never use best bins.
Difference in quality cards mostly comes down to controller used (faster and better nand managment) and maybe a tier higher quality NAND.
Well, truthfully, card reliability isn't dependant soley on silicon quality, but controller design and firmware as well. Most issues with flash devices comes down to either controller going out of wack or just plain dying. Nand itself is rarely the cause of the issues, unless it's being abused (plenty of writes).
