HDD replacement before catastrophic failure
Since the last 2 days my MBP has been really sluggish with spinning beachballs for every activity. The HD is on the verge of a catastrophic failure. I'd like to replace the HD with a new SATA 500gb HD , however, I'm not sure about the size of the HD. Should I go for the 2.5 inch 7mm or the 9mm? Also, it'd be great if any particular brand is recommended. Thanks a mill!
Is this a good question?
