VRAMFS: Using Your Video RAM As A Linux File-System

[vmicho]

Ramdisk cards already exist... and would be far faster probably a bit quicker than an SSD.

Remember GPUs are not optimised for quick transfer to and from but for fast access locally between VRAM and GPU.

Well, in fact, they were the first (or one of the first) SSDs in fact. They were here long before the flash SSDs.

Here just a short quote from another site:

Here's a simple rule of thumb based on analyzing published price data - for identical storage capacity - across a wide range of commercially available SSDs.
* RAM SSDs cost 9x more than SLC flash SSDs
* SLC flash SSDs cost 2x to 6x more than classic MLC flash SSDs (2 bits per cell MLC)
* classic MLC flash SSDs cost 1.5x more than 3 bits per cell MLC SSDs
