It is probably better to have a lot of RAM, so that swap is not used that often, and move swap back to SSD as difference in access speed is rather dramatic; you don't have movable parts that need repositioning and pure transfer speed is few times higher.
8 gb of ram so swap is infrequently accessed and access/transfer speed hardly ever noticed. Perhaps negligible effect either way so present method really of little importance. Large amounts of ram do contribute to sloppy management, ie: many pages open on firefox although rarely accessed, ... Private memory: Firefox 1.4 GB Darktable 1.6 GB Virtuoso-t 0.5 GB Other usage: Cache 4.3 GB Free 0.9 GB Swap 0.0 GB
Of course if you use hibernation that will tax swap space, but when one is worn out, after say 2000 writes, you can use different part of the disk that wasn't used that much and repeat that as long as remain disk capacity is sufficient for your needs.
Desktop so hibernation not an issue.
The lifetime of a drive is different from individual memory cell endurance as built in controller will stop using bad block, just the same way it happens with classic, mechanical, drives. How far this can go depends on a size of memory that is allocated to hold index of bad blocks.
Understood, tks Presently considering increasing ram to 16 GB and removing swap completely and replacing 120 GB SSD (really adding and reassigning function of) w/240 GB or 500 GB SSD. tks, -- (paka)Patrick Shanahan Plainfield, Indiana, USA HOG # US1244711 http://wahoo.no-ip.org Photo Album: http://wahoo.no-ip.org/gallery2 http://en.opensuse.org openSUSE Community Member Registered Linux User #207535 @ http://linuxcounter.net -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
