I suspect it would be difficult to properly balance writing across blocks with only 100 cycles before wearout.

- Zandikar 4y agoDepends. If you're trying to use it as a drop in replacement for a Scratch/Boot/Database drive, sure. That'd probably not be a good plan. But if you consider HDD's are primarily deployed in WORM or WFRM (Write Few, Read Many) work loads these days, a 100 P/E cycle NAND flash that has comparable $/TB value to spinning disk could definitely have a viable market. It'd be kinda like Flashes version of Shingled HDD's. Got be a bit more careful with their usecase, can't just drop them in whereever and expect it all to work fine, but as long as you use them in WORM/WFRM, they'd be excellent for greater physical data density and far superior power efficiency.
