Samsung 960 Pro nvme m.2 as RAM disk vs. real DDR4-3200C14/DDR-3600C17

[modeonoff]

Hello, trying to decide between 64GB or 128GB. 128GB is very expensive. Buying 64GB now and later upgrade to 128GB may caue issues due to "different bins".

I wonder how is the performance of turning a Samsung 960 Pro nvme m.2 as RAM disk. Which is faster? Real RAM (DDR4-3200C14/DDR-3600C17) or RAM disk? Any pro and con doing this? Also, if I have y GB of SSD, will I be able to turn it into y GB of RAM disk? The OS will be Ubuntu Linux.

Thanks.

You have ramdisk backward... you don’t treat the disk as ram — you make the system believe that a portion of ram is actually a hard drive to gain max speed and minimal seek.
