I am sure these threads have popped up a lot recently, but I need some new input on this. I don't think I will do this right away, but I may consider buying two SSDs soon (one for my 2009 MacBook Pro and possibly one for my PMG5). 1. What is the best one to get? I don't want to spend real money, and I thought a nice Kingston 120GB SSD for $59-ish dollars sounded good... what do you guys think? 2. Trim... I hear that older Macs/older MacOS versions don't do well with what is known as "Trim". Can someone explain that to me? I am running Leopard on this G5. (the 2009 MBP has Snow Leopard). Do I have to worry about things on the PowerMac G5 apparently "getting slower" over time? 3. Can any SSD work? I am assuming the SATA connections in my G5 are the same as those in a laptop? (considering people buy 2.5" SSDs for their desktops and put in a 3.5" mounting bracket) 4. Is this worth-it in the G5? I can tell it will be for my MacBook, as the mechanical HD messes with its sleep process, etc. But, for the G5, is it a noticeable speed increase? To give you an idea, I have an original 2003 dual 2.0Ghz G5 with 8GB of DDR1 memory. Will I really see a noticeable different that is worth the $60-odd? Thanks in advance for your offers. You don't have to answer in my list format, but please address all -- if not -- most of my questions!
