I've got a 2009 MacBook Pro 17". Great little computer that I love to use, and I recently upgraded it to 8Gb RAM, which is the maximum this model can take I believe. However, last week, I noticed it taking a long time to boot up, so I ran a full disk check, and it told me there were corruptions on the disk that it could not repair, even doing the full reboot and running the disk utility from the diagnostic menu couldn't fix the issues. It seems to be working fine, but a bit slow now, so I think the 500Gb HDD is on the way out. Thinking of swapping to SSD now, but I notice a big price differential between the 500Gb and 1TB SSD drives. Are the 1TB models as reliable and fast? Seeing as my 500Gb drive is quite full now, I thought 1TB might be the way to go. Additional question - how do recording apps like Garageband, Logic X etc. behave with SSD drives? Faster? Less issues with the whole thing slamming to a halt when there are too many threads running?
