My 2010 MBP is going to my mom since her PC died (finally she's going to try OS X!). Anyway, it originally came with a 250 GB HDD that I pulled and put in an older 750 GB WD HDD. Would it be best to put the 250 back in? Is there any benefit with it being an original Apple (I know it's probably Seagate)? It's a 5400 rpm, vs the upgraded 7200, so it should save on battery. And I doubt she'll use anywhere near that much space. Her PC hardly had 20 GB used, but it was a pain to use. I'm keeping the 8 GB of RAM in there, for sure. It runs so much smoother with it.
