GpuRamDrive

Create a virtual drive backed by GPU RAM.

Screenshot

This application simply allocates a memory buffer inside GPU RAM and use it as virtual ram disk. The project is made possible by ImDisk and its proxy feature.

Using GPU RAM isn't as fast as host main memory, however it is still faster than a regular HDD. The result below is taken on my system with GTX 850M and i7-4710MQ. As IO operation is happening between the CPU and GPU, the GPU can become active from idle state and might causes system to draw more power. This merely just a PoC, user who search for this kind of solution is advised to upgrade the RAM or buy a faster storage.
