This reminds of how ddr3 prices came down, I bought some and it got cheaper and I bought some more for upcoming builds, just kept getting cheaper. I picked up an M4 256 last week from Newegg for $169 -- didn't need it, but I can use it somewhere. I think we'll be seeing them under $150 soon. Looks like all that talk of a price war in SSDs may be happening with Crucial on the front lines.
I have not ordered one yet as I have a 128 gig Samsung 830 that I have not installed yet. Might consider one for My laptop to replace the 128 Gig M4 (next Month), but not really pressing as my OS + programs are only eating up about 35 Gigs (not a gamer) and I have a 2nd 128 gig M4 installed in the 2nd drive Bay.
