- RAM drives are insanely fast, but are they a worthwhile project?

wait, cant you just download more ram? I did that
Help! I just downloaded more ram off the Pirates Bay and it is not speeding up my computer. Should I also download a new broadband/PCI-E slot? I k ow they are virtually the same thing but I will buy both if needed.
wait... if the cat chews the power cord between the UPS and the desktop Power supply you have the same problem..
But Linus... A UPS wouldn't help you if your cat chewed up your power cord...
The ultimate speed drive you could ever hope to have: cpu cash drive. It WILL be a thing eventually.
I use RAM disks for my chrome cache
Gaming on RAM with an i9 9900k and a RTX 2080 ti.
SoftPerfect RAM Disk ftw. As a ramdisk user, I must note that bluescreens are a much bigger problem than loss of power.
Wait how about L3 cache storage!?!?!
I actually use my RAMDisk as my downloads folder. Seems dumb, but it means I get a nice purge of my downloads folder when I restart.

If your cat chews on the power cord you will lose more than your data! :O
Linux has this function built in. You can easily create a ramfs with the mount command:
Hold on, at
Btw, your operating system already stores frequently used files (like some browser files, or files you r/w to frequently) on unused ram, so don't fill up your ram too much.
I have 12GB RAM but use a 3.5GB RAM disk not for speed, but to stop continuous writes to my SSD. My main use for this is NVIDIA Shadowplay: a 7.5 minute recording at 1080p 60 FPS in high quality takes up about 3GB in temporary files (which are automatically deleted when you save the recording) but is always recording in "Shadow" mode. Another use is for saving downloads and then running the installers/apps from there; since it'll be faster too and you'll get rid of them anyway.
I use SoftPerfect RAM Disk and it's terrific. Also, free. I run a couple VMs off of RAM disks, XP boots in about two seconds.
I'm thinking ram drive might be ideal for undo/redo states that are saved to disk and are very large. The files wouldn't need to survive a boot.
I remember playing around with RAM drives back in the eighties, you could purchase the card and install your own ram with a nice little battery backup if you wanted, and I had the operating system copy over on startup. Mind you, operating systems were a lot smaller back then so it only took about five minutes. Nowadays it almost takes that long just for the opening sequences to load up these days.
