The external PCIe RAM disk based on the DDR memory instead SSD?

[Tinetta]

Hi all! I work with video editing and I need a fast disk for buffering etc. Will this device work for me?
I tried virtual disks directly in PC's RAM but it has too small a volume... I need 1T or more.

For the price of that, you could buy a decent 2tb nvme, a decent amount of normal DDR4 memory and still have change left over.

The resource is a priority for me. Fast SSDs wear out too quickly. High TBW models are too slow as a rule...
