I am wondering if i have only 4GB ram and somehow(virtualbox,browser) isn't enough and i cannot proceed to upgrade(due to ultrabook and soldered memory) will swap held in SSD help the overall performance??


  • Do you have a hard disk in your notebook? – ott-- Apr 25 '15 at 21:14
  • No i don't have HDD, it is a Dell XPS 13 Ultrabook and the ram is soldered as told in my question. Also the only available disk is the ssd included which is bound to m2 sata port. – shad0VV Apr 25 '15 at 21:51

Swap on SSD is going to be much faster than swap on a magnetic HDD. But it's still going to be pretty bad compared to having sufficient RAM.

Also, if you're thrashing to SSD, that's going to cause a lot of writes—it may wear out your SSD.

I'd suggest looking into zram and/or zswap to make your 4GB go further.

  • How about hdd with massive cache, or ram based ssd (usually battery backed, though you will have no need for the battery). – ctrl-alt-delor Apr 25 '15 at 21:36

    @richard you'd need a truly massive cache to matter. And yeah, one of the battery backed RAM cards typically used for databases would be fast, but I suspect it'd be cheaper to buy a new laptop. (And they're often PCI cards, which I doubt will fit in a ultrabook). – derobert Apr 25 '15 at 21:39
