In my search for a SSD, and looking at the new ones that handle SATA 3, I had to take a closer look @ my own specs. Looking like there's no need for me to buy any of the speed demons as my GEN 1 MacBook (yes, THAT old one - lol) is SATA I from what I can see.
ICH7-M AHCI 1.5 Gigabit
Which of the MacBook Pros are Sata 3? Or are these s/w upgrades? I have a 17" 2009 I recently inherited and would consider making the speedy upgrade. + I will be making the move on the MacBook Gen 1 too eventually but doesn't look like I would be able to take av of the 6G or even 3G speeds.
Yes that will work just fine. Actually you could put in a Sata III drive if you really wanted...you just wouldn't get the speed benefits so unless you're planning on putting that drive in a new machine very soon I wouldn't bother.
Aren't the latest SATA III SSDs (and other SATA III HDDs) all supposed to be backward compatible??
Some manufacturers may suggest using a jumper if it's even an option, to restrict such drives to the lower 1.5 speed if it's actually required for use with older Macs.
Still pretty fast even at any lower "restricted" speed — IF it's even required.
