Hello guys, Im new to the Mac world (used them before at school, but never owned one) and I'm looking for some advice. I already tried the search function, but I don't get the information I'm looking for out of the threads. I also tried google, but most of the information is outdated. I own a mid 2010 MBP, with currently the stock 250GB Hitachi hard drive and I'm looking for an upgrade. At first I was looking at the 500GB drives but then I bought why not go to 750GB for a little bit of extra? I'm a graphic designer so the extra space won't hurt. Then came the first complication; do I buy a 5400 rpm or a 7200 rpm?! I know most of you will say the difference isn't that noticeable, but it will improve my boot time of apps like photoshop and lightroom. Will the 7200 be a noisy battery sucking drive? Or does the power consumption of 7200 drives these days almost equalizes the 5400's? The second complication is; what brand? I was looking at Seagate disks (the Seagate ST9500325AS |500GB 5400RPM| & Seagate ST9750420AS |750GB 7200RPM|) because of the pricing and reviews. I have a Windows pc running and always been into the Western Digital disks, but I can't find positive feedback on those drives for the MacBooks so that brand is a doubter. The Samsung disks didn't impress. Then I bought to be a smart guy and put a Hitachi in it like the stock, but I could only find the Hitachi Travelstar 5K750 (750GB 5400RPM). So basically I'm looking for help and opinions. 1. Will I notice that I'm running a 7200rpm disk? (sound & battery drain) 2. Which brands work well with the MacBooks? An SSD is not affordable for me when it comes to 500GB. Thanks in advance!
