At first i thought ReadyBoost means having swap file allocated to flash drive which is wrong because ReadyBoost serves as additional storage for swap file or should i say it mirrors swap file on hard drive and has first priority?
Anyway, i thought about allocating swap file to flash drive fully. How would that perform? Will it deplete flash drive's write cycles fast? I also think it would be more convenient with SD flash card since it sits inside laptop's flash reader and does not stick out.
Now the best option is to buy more RAM, but what if to create RAM disk out of current 4GB of RAM that i have and fully allocate swap file there? Create 2GB RAM drive or just buy additional 4GB of RAM and create 4GB RAM disk?
My objective is to have swap file on flash media or better on RAM disk. While latter sounds better, it would be more expensive and will require disassembling my DELL Latitude E6420 laptop (i did not find RAM cover).
