Hey guys! Almost all day I have been trying to figure out what the best upgrade is hard disk wise for my MacBook Pro 15 inch from 2012. My eyes keep falling on the Western Digital Scorpio Blue 1 TB and the Western Digital Scorpio Black 750 GB. The Blue one being a 5400RPM drive and the Black one being a 7200RPM drive. I have been reading so many mixed reviews on both drives. The one says this, the other says that. For me it's most important to have a fast drive. Battery life is not so important, although of course the quieter and less vibrant a hard drive is, the better. The 250 GB difference in space is not an issue for me. But I have been reading that the Blue is almost identical performance wise as the Black, but is a lot cooler and quieter. But some say the opposite. I cannot really get my finger around it. Do you guys have any experience with these drives and can recommend me the best option out of the two? Is it really true the performance is almost identical? Cause if that is the case, the most logical option would be the Blue as you get 250 GB more space. Thanks for helping me out! Much appreciated.
