I am trying to run a simulation and need more RAM for a big array. I'm at about 24 GB and need about 100 GB.

I have an external hard drive with 2 TB of memory, so is there a way I can use this to increase my current RAM? I am not too good in Ubuntu and know how to do this with Windows, and am hoping someone can help (or at least tell me yes I can do this.). Thanks!

While you can use an external drive for swap, that will be very slow. – HuHa Jun 29 '21 at 15:28

If you can, use a SSD drive instead. – paladin Jun 29 '21 at 15:41

NVMe or Intel Optane should be good. External HDD will give you <250 Mb/s, you should know this before the start. – N0rbert Jun 29 '21 at 17:29
