Upgrading Your MacBook Pro with a Solid State Drive
If your Mac is fast enough to use a SSD, definitely get one...... but if it isn't fast enough for a SSD and you are happy with the laptop and just want more space, 1TB hard drives are only about $100.
Irrelevant. The biggest advantage of a SSD is not a matter of the speed of the interface but the lack of latency. A SSD that is throttled to older SATA speeds will still be lightning fast compared to a hard drive.
A while back I had a port failure on my main machine, the temporary fix was to move my SSD to a SATA II port. I didn't even notice the difference.
