Right now I have a 2011 MBP with the Apple 128GB SSD in it, and a 500GB WD 5400 rpm HD in the optical bay. While this is working for me, I'd rather move to all SSD my my machine. I have noticed that I rarely ever use more than about 300GB worth of storage, but regularly use more than 240GB. While money isn't a huge concern, buying a 480GB vertex 3 is a bit hard to swallow. So my thoughts are, go with a 120-128GB boot drive and a 240-256GB drive for data and VM drive. First off, I happen to have a 120GB Gskill Phoenix SSD sitting in a box (it's a Sandforce 1200 based SSD). I am planning on swapping the 128GB Apple SSD with the Gskill. My old 2009 MBP had a sandforce 1200 in it and it felt a bit snappier. I thought about picking up a 120GB Vertex 3 (or Corsair Force 3) drive, but the reviews of the 120GB Sandforce 2200 drives are not showing a lot of improvement over the 1200 series due to half the memory channels. Secondly, anyone have any recommendations on a "cheap" 240-256GB SSD? It seems like the Sandforce 1200 series is about the cheapest. Newegg has them for around $380. I was surprised that a lot of the slower/older chipset based SSD's weren't cheaper on Newegg. Last, what about the new Crucial M4's? It looks like the 512MB ones are running about $850. While they aren't as fast as the Sandforce 2200 based drives, at that price for a Half TB, I think I could swallow the price (as opposed to $1700 for the Sandforce 2200 drives). Any experience on how these drives work with or without the TRIM hack? It would be nice to put my optical drive back into my MBP for the handful of times I use it, but it certainly isn't a requirement. Any and all help would be/is appreciated.
