Transfer speed is not everything, latency for random access is one important factor and also performance with randomly accessing many small files... Something e

  True! All of that would still depend on the way the memory is being accessed though, and if you really want to maximize the speed at-hand then you'd need a powerful memory controller. Once we get to this stage in the thought-experiment though, I think it makes more sense to install the RAM into a normal system and use a RAM disk to store things in it. It's an interesting question, but I think the circumstances explain why nobody has really commercialized something like this. NVMe will get you 90% of the way for 30% of the price, and it's non-volatile to boot.

  But nvme has lower latency than SATA. A ram disk over SATA just doesn't make sense.
