Hello, I just purchased a Macbookpro 13 2.26 ghz, and now I want to upgrade it (for sure to a 500 GB HDD). I want to use my laptop for photoshop, Lightroom, maybe Aperture (shoot my pictures in raw). While I am editing my pics I would like to listen to music, download music files, use ms office etc. What would you recommend me with regard to the size of the ram? Is 4 gb enough? I think that I will choose Crucial. Is there maybe another good brand, because I was searching on the forum and I can only find threads recommending Crucial. Is this the best choice? With regard to the HDD, I think that the majority here either has a WD Scorpio Blue 5400 rpm or the Seagate Momentus 5400/7200 rpm (AS version). I have read many posts about it and I have the impression that the Seagate is more reliable but I am not sure about it. How about Fujitsu and Hitachi, I dont really read something about those brands. I met a guy who has been repairing computers for 15 years and he swears by Fujitsi for laptops, since they are the most shock resistant hdd. I also read a thread where it says that the 7200 rpm doesnt work well in the 13. Is that maybe also the reason why you cant upgrade it to the 7200 rpm on the online Apple store? Since I will mainly use it for processing pictures I would like to have a fast hdd but after reading the thread I am more inclined to stick with the 5400 rpm. What are your thoughts about it? Is it true that the 7200 RPM doesnt perform well in the 13? If I do a lot of pictures processing, is it much better for me to go for the 7200 rpm or is the 5400 rpm fast enough? Will the 7200 use much more power (I am going to live for a year in a country with many and long power cuts), make a lot of noise and make the laptop very hot? I also want to buy an external harddisk to backup my pictures. I want to go for the 1TB. I saw Buffalo which seems very good. Does anyone of you have any experiences with Buffalo? A second choice is Seagate but the problem is that it automatically makes a back up but this is already my backup, so I need to delete it afterwards, which is more troublesome. But if the Seagate is much better for the MacbookPro I would of course go for the Seagate. Unless you can recommend me another better brand. I am so sorry for asking so many questions. And thank you so much in advance for taking time answering them!
