I think the original question came up after the recent Rails keynote where they mention that, with NVMe speeds, disk is cheaper and almost as fast as memory, so Redis is not as vital. https://youtu.be/iqXjGiQ_D-A?t=2836
So Solid Cache and Solid Queue just use the database (MySQL), which uses NVMe.
So now, in addition to: "You don't need a queue, just use Postgres/MySQL", we have "You don't need a cache, just use Postgres/MySQL"
Right, that is cool, but unrelated to the OP of using NVME directly and bypassing the filesystem. Or does MySQL have a storage driver that talks directly on the NVME level? (I haven't used MySQL in more than a decade, mostly PostgerSQL now)
