Do RAM expander apps for Android work as good as having actual RAM of the size expanded to? Please elaborate
well one is inbuilt the hardware and the other is kind of external,
Thanks. Pl note that q implies functional and not physical difference
inbuild will be faster in read/write but nowadays things are not slow with sd cards this also depends on the kernel/firmware...
RAM expander apps create virtual memory, similarly to what Windows operating system does when the memory is low. The performance is slower than having real RAM, but allows for more memory usage than the physical RAM allows. The read and write speeds are lower on internal storage, and depending on the read and write speeds of external SD cards, may be even slower. Getting an SD card with high random read and write speed would allow for better performance. This does not mean getting a class 10 SD card because the high speed is based on sequential read and write speeds, so a class 4 or 6 may perform better. This being said, virtual memory (RAM expander apps) will not be as good as actual RAM, but instead would allow some apps to run or allow better multitasking than without the use of the virtual memory.
Note: using RAM expander apps may introduce and cause glitches and errors on occasion. The benefits and risks need to be considered before using such apps and configurations.
Thanks for elaborate answer. Can you web link a free app which can use either internal storage or memory card or both as RAM?
Also elaborate how would using RAM from non default sources that perform slower read write process affect additional Random memory which would be available?
This article can explain the use of swap files better than I can: http://zerocredibility.wordpress.com/2009/08/24/why-android-swap-doesnt-make-sense/. This would help in setting up, installing, and configuring the swap file using Swapper 2: http://forum.xda-developers.com/showthread.php?t=1659231. Here is a link for Swapper 2: https://play.google.com/store/apps/details?id=org.azasoft.free.swapper&hl=en.
Thanks! The app which you mentioned requires rooting but the app mentioned in the following video does not require rooting : http://www.youtube.com/watch?v=omEZcZF1zNU
Can you weblink the apk of app used in video?
Unfortunately, SwapIt RAM Expander, which was in the video, is now Roehsoft RAM (Swap) Expander. The video linked to pirated software, which was why it was said to be free. The new RAM Expander costs around $10USD, and requires root access. I have not been able to find any free apps that do not require root in order to create RAM expansion/swap files. Also, many devices do not have kernels that allows for proper swap file creation and allocation. There is a free app, still requiring root, that would be able to test if the kernel is supported, as well as test to see if the swap file usage would be stable enough for use on the device. https://play.google.com/store/apps/details?id=com.roehsoft.meminfo#?t=W251bGwsMSwxLDIxMiwiY29tLnJvZWhzb2Z0Lm1lbWluZm8iXQ..
Many people do warn that using swap files will reduce the life of SD cards, whether internal SD storage or external. Internal storage degradation would be very costly because it cannot easily be replaced, so using an external SD card would be highly suggested.
Here is a link for a review about SwapIt RAM Expander by Roehsoft, and if you click on Download from market, it will take you to Roehsoft RAM Expander instead (the new version with a newer name): http://apps.talkandroid.com/apps/tools/346468-comswapitexpanderde/.
