Hi everyone, i've read almost every post around here about SSD's and i still can't decide which one to buy. I own a mid-2010 MBP, and everybody recommend Crucial M4 or Samsung 830 altough my machine has SATA II. Well, a few days ago i received a 100 gift-card from a store of my country (Spain), so i decided to waste it on a SSD. The problem is that in that store they only sell OCZ Vertex 4 SSDs. The Vertex 4 will cost me 159, while in other stores the Crucial M4 cost 215 and the Samsung 830 230 (all in the 256gb version). Is the Vertex 4 a good option, or should i go with one of the populars and much more expensive ssd (Crucial or Samsung) ?? Thanks in advance for your advices and sorry for my english. Best regards.
