Hello, Im considering upgrading the OE 200GB 7200 RPM HDD in my Macbook Pro 4.1 (2008). It is a 4GB, 2.6 GHz C2D setup. Ive read the guide, read a LOT on TRIM and other things. I realize that this is only a 1.5 Gb/s SATA setup, but I feel that the other benefits really are good. Im running 10.5.8, and because I have a setup with a dual boot NTFS partition, boot camp, parallels, etc., Id prefer to go with an install based upon imaging the partitions to be functionally the same. My top choice right now is the Samsung 830 in 256GB size. I figure in the future if I replace MBPs, I can always re-use this drive and put the old HDD back into this MBP if the computer is still functional. While I saw the recommendation for intel 320 drives, the price point compared to the 510 and the 830 doesnt seem attractive (particularly because I want 250 and so Id have to buy a 30GB model 320, vs a 250GB 830 or 510). So, with all that, any reasons not to select that drive? It seems like trim isnt really that critical of a thing, and the drives are better at garbage cleanup. Most of the files Id write are <=10MB. Thanks!
