SSDs and HDDs

[Steven Jones]

Hi,

There are it seems always exceptions, LOL, you dont hibernate servers, which is my focus.  Generally though for actual use 2gb of swap provided you have adequate ram is simply mostly un-used.  More importantly if you do get to the state of using more than 2gb of swap (actually any swap frequently) the machines response is likely to be so bad you wont accept it and you will buy more ram.   So 2gb swap will save your bacon long enough to get more ram added.  In terms of hibernation with ssds now so available your machine is going to boot clean in some 10s of seconds which would be how I would operate.

"links" is simply experience with dealing with some 100s of linux servers for 15 odd years.  

regards

Steven

Could you provide links to explain this claim?

Regarding this information, a large swap size could be useful:

You even could use an existing install, by simply copying
(sudo cp -pr old new) from an existing install to the new drive. You
just need to edit /etc/fstab and to correct the bootloader and you
need to care about the order of the devices by the BIOS settings.
