Thought macrumors should know about my recent hard drive upgrade woes. I have a 2.4 2010 model and it only had 250gb in it so i wanted to upgrade to 500gb. So after doing some research i purchased a western digital caviar blue 500gb 5400rpm from best buy for $60, HD was so loud i immediately took it back. So now i exchanged it for a seagate momentus 500gb 7200rpm because everyone on here said it was great this HD was $90. After using it for a couple days yes it was somewhat quieter but still not as quiet as oem. Another issue with the 7200rpm drive was battery life, some people on here say you dont notice but i did and battery life is very important to me being a student and not wanting to carry around a charger. I bought this computer because of the 10 hour battery why would i wanna sacrifice it. So took back the seagate and ordered a oem hitachi 500gb 5400 drive of ebay. I was able to find one claiming to be new and pulled from a macbook pro becuause it was replaced with a SSD. I got this HD for $45. Everyone is gonna laugh but i sold the oem 250gb on ebay for $55 used so im actually ahead $10 !! At the end of the day none of the aftermarket HD's were comparable to oem!
