In the days before SSD's this is what I used to read and dream about!
HyperOS - Hyper Drive: An insanely fast, RAM based, battery backed up IDE drive.
I've searched for one for literally 2 decades and never seen one for sale, one day, one day!
@Gammitin I once found a UPS in that form factor. I still occasionally regret not buying it.

Wow; what a gadget. In the days before NAS (early 90s) in TV we used a solid state network storage device called a Questech SSVR which you could FTP frames of video to/from. 500Mbytes and 10BaseT networking!
