Currently I have a Crucial M4 256GB, but with SSD prices going down I've been considering buying something faster and putting the Crucial M4 in my laptop. The two I'm looking at are the Samsung 830 256GB and the Mushkin Chronos Deluxe 240GB. The Samsung 830 goes for $240 - $250 while the Mushkin is on sale for $175 with a $20 MIR (Canadian prices). I know the Samsung 830 is a more reliable drive, but would I be better off getting the Mushkin at that price? Is there a noticable speed difference between the two?
