![]() The estimated drive lifespan is 75 years (the pessimistic one based on maximum erase count value which is now around 200 and average one is 130). But the benchmark doesnt show any degradation in both read and write in any part of the drives (well, I tested the one half of the drive which is free and the swap partition). In total, over 3 years of heavy swap use, the MLC drive wear is 4% and it's small drive 250GB and the second one is 97%. Note that this was tested well only on two laptops with two different Kingston drives but with the same controller. After 1 year of operation and heavy use, and lot's of paging, the whole drive has normal performance, including swap partition. The second workaround I did was to increase pagefile to over 25GB size by secure erasing drive and reinstalling the whole OS (and while keeping this discard on). ![]() I have read that during reboot it is discarded anyway. So the first workaround I did add "discard" option to the fstab of the swap partition and also I discarded the whole partition and another half of the drive but it didnt improve much, after few months swap partition still had 50% of the performance. What I have noticed with gnome-disks benchmark, that the areas where there is pagefile slows down a lot very quickly, sometimes it becomes even slower than HDD. ![]() I have few low RAM laptops running desktop Linux and various SSD drives, and 4GB is today far too little so they are paging a lot to the SSD. So as long as you don't mind the idea that you could potentially wear the SSD out faster (though no faster than putting the entire OS on the SSD to be honest) then there is no reason not to put your page file on the SSD as it should perform better than the hard disk. There is also Intel's latest Smart Response which is effectively another version of the ReadyBoost technology. USB sticks are dirt cheap, come in all the major helpful sizes (4GB, 8GB, 16GB and so on) and for small reads and writes are pretty comparable to an SSD. Sadly it seems that many SSDs fail after 1-2 years (see here for some failure rates during the first year), but this is typically due to failure of the SSD's hardware or firmware, rather than wear of the flash memory. Typical flash devices these days are getting as low as 5,000 write cycles for a standard MLC device, with the manufacturers using wear-levelling algorithms to help the device last longer. ![]() It works in a vaguely similar fashion (caching hard disk reads instead of caching virtual memory - but the theory of the method of performance boost and flaws are the same) but has very similar reasons for limitations as putting a page file on an SSD:įlash based memory has much poorer write tolerance than spinning-platter or full-on memory chips. While people are suggesting you do not put a page file on SSD there is nothing to stop you, there are also similar-ish ideas such as Microsoft's Readyboost, though it uses a USB stick instead of an SSD. ![]()
