I currently use two solid state drives on my t420. the intel 310 80gb is just the os. and the hyperx 120gb ssd is for games. i have another 500gb wd black hdd in my ultrabase. i am really interested in buying a p34h to expresscard or pci-e adapter because my nvidia 4200m was severely damaged in an accident. i could take the intel 310 out and just use the pci-e for graphics performance and use the hyperx ssd as os and maybe a game or two, but i am not sure the pci-e adapter is even compatible with my thinkpads msata port. does anyone have experience using the t420's msata port for graphics?

I am thinking of buying a GTX 560 1GB from MSI (fermi N560GTX-M2D1GD5) and connect it either by pe4h via expresscard or by msata. can anyone give me an idea of how much performance my t420 will gain from this, if any? i can't play my games

i know expresscard works, but if performance would be faster with msata pci-e port then i'd rather use it. also i can turn on my computer with optimus or nvidia graphics on, but it turns on really slow, stutters and randomly turns off, usually after i turn on a game or video. it runs fine with just the integrated graphics. my games run too, but not nearly as well as they did with nvidia (i have to lower resolution to 800x600 to get a decent framerate). please help me out if anyone can, i need advice!

I am not sure but there is a thread on NBR solely dedicated to eGPUs. Here is a link.
