The 510 in question is slightly cheaper than M3P/S by about £10. Almost wondering if better choice might be betweern 256GB 830 or the 240GB 520 now though
EDIT: Well I ended up not bidding on 510 which went for £250, same price as a current gen 256/240. I have recently started pc gaming again after many years away and 120GB is eaten away fast. It is so hard getting an ssd! one performs better here, another there one has a better controller, one better warranty ad infinitum .
