i have a laptop which has 6gb of ddr3 ram and the problem is that i'm quite constantly running into 90%+ usage. so i began thinking about giving it a bit of a boost for better multitasking.
Now, the laptop has a pretty awkward configuration of 4 and 2 gb sticks in 2 slots, so all the slots are filled. as i understand the only way for me to upgrade is to either take out the 2gb stick and replace it with a similar 4gb unit or to use the readyboost feature. The replacement of one stick seems to be a sure bet. but i'd rather save some cash now. so i'm looking into other options.
what makes me think that the not-so-popular boost feature might be decent enough is that i have a usb3 connection and an external usb3 HDD (not a flash drive, but an hdd), so i could just chop out like 4 gb of memory from that hdd and use it for a boost. sure, a usb3 hdd can't even come close to ram speeds but it might just be enough to clear some space from real ram.
Bad Idea , USB even 3.0 is massively slower then Ram , even using a hard drive for an increased page file is not good since laptop hard drives are slow.
As I see it you have two options , swap out the 2gb stick for a 4gb or change the internal hard drive to a SSD.
