Copy the vhd/vdi file to the RAM drive and make the appropriate mappings in your virtualization software.ĥ. (Remember that the RAM disk size is limited to the amount of free RAM on your PC)Ĥ. Create a RAM disk that is large enough to fit the vhd/vdi file of the virtual machine. I found “ Softperfect Ramdisk“, “ VSuite Ramdisk” and “ Dataram RAMDisk” to be quite nice, but anyone should do fine.ģ. ![]() A list of RAMDisk creators can be found here. Create a virtual machine and install the OS you want to run from the RAM disk.Ģ. (SPOILER: It would be blazingly fast!) To test this out, I created a RAM disk and placed a virtual machine’s hard drive (vhd/vdi file) on that RAM disk using the method outlined below:ġ. (HDD is the slowest) Imagine what could happen if you would use the system’s RAM instead of HDD to store and load applications and files. ![]() Now to the fun part!! Apart from built-in CPU cache, RAM is the fastest memory in a PC. There are enterprise grade disks that spin twice as fast and if built in a large RAID array they provide good balance between performance/storage capacity and price.) RAM disk experiment (Disclaimer, my HDD’s spin at 7200 RPM and are of consumer grade and also quite old. Clearly, SSD’s are way faster than HDD’s even if two HDD’s are used in a RAID.
