I've been curious about upgrading my HDD into an SSD for awhile now but so far do not have the budget. Now though I worry I may have to jump the gun on account of my drive failing. Although it's SMART status is still verified I've noticed some odd activity from it lately. The first indication for me was that it's normal spin up sound (the sound it makes when I wake my computer or what have you) has changed slightly. For years it sounded normal but now it sounds scratchy like the drive is having trouble spinning or getting stuck on something. I don't know. The second indication for me is the start time. Part of this is to blame on the RAM I'm sure but my start-time has gone from about 30 seconds when I got the macbook, to 3 minutes when I upgraded to Lion and is now over 5 minutes even if nothing needs to re-open. This doesn't seem right to me at all. It shouldn't take 5-10 minutes just to restart my computer. So, yeah, should I be worried? Does this sound like HDD failure?
