Hey guys, Now before I start, I just want to say I've done a whole lot of reading on what I should get, but just need a little push in the right direction. I was basically set on getting a Samsung 840 PRO 256gb, but the shop I found a good deal at only stocks the 850 now which is about $50 more. My situation: I currently have a 2010 MBP 13" which has gotten a little sluggish lately. 4GB RAM, 2.4GHz processor, 250gb HDD you know the drill. Looking for something to give it an overall performance boost and I feel that a SSD is the best move Here's the dilemma however in my reasoning; I'm going to be in the market for something bigger, either a 15" or 17" used MBP, probably rocking 8-16GB RAM and another SSD with 256gb+ pretty soon. So in saying that, I don't want to spend TOO much on this SSD for this mac. I've had a look at a few options; and noticed most are SATA III (I know they're backwards compatible) but the mid 2010 MBP is SATA II and I won't experience the upper end of the write/read speeds of the SATA III SSD; so it might be worth going the cheaper route. Secondly, this laptop is a bit of a throw around laptop but I want to have a bit of speed about it. So is it worth spending a little less money and getting something like a Kingston or Intel 520? Or should I go with the 256gb Samsung 840 Pro or Evo and bite the bullet spending a bit more? I think I'll go for the 512GB Samsung 850 PRO on the new laptop; but again don't want to spend that much on this. Just looking for suggestions on whether I should go for something like the 840/850 PRO or something like the EVO/Kingston? It needs to be consistent, but it doesn't necessarily need 70 years of life as it is the second throw around laptop. Additionally, I don't use it as a gaming laptop or render any 3D, the most I have open is a lot of tabs on Firefox, Photoshop, Illustrator and other basic appliances at any one time. Thanks in advance. Here's what I can select from and the prices beside them: Apologies for the post in two sections, need a response ASAP.
