Your are correct EveryMac says it's likely a SATA II, so, a SATA III drive would be backward compatible at the lower speed.

Most of the SSD / HDD are backwards compatible - as the manufacturer always promises backwardfs compatibility, it is not a must in practice ;-)

I installed a Kingston 240 GB Sata 6 GB to my Mac 2009 with C2D processor and Sata 3 GB and noticed a slight increase in speed, but more in agility. I measured around 100 MB/s while constantly writing ... the same disc in a i7 Mac with Sata 6 GB does 490 MB/s in the same test.

This will be the main difference.

Some people here have had problems because claims of backward compatibility proved false... or the drive had to manually jumpered to downshift. That's why I mention it.


Same to me, machead03 :-) I tried to show that the actual SSD drives must not behave the way we expect when installed to older computers. In my case the SSD reached not much transfer rate above normal modern HDD drives, but the response is even much faster and makes the system reacting "smoother".


I'm running a Samsung 850 Pro in my iMac 27in mid 2010 and it's worked like a charm. It is correct in saying that it only utilizes SATA II and thus is slower than the newer SATA III. I'd still say it's a worthy investment if you're trying to breath new life in that 2010 beast. I also replaced my i3 processor with an Intel i7 870 2.93 Ghz with 16gb of ram.


Stone, so you would say it wouldn´t be a significant change in rate for the investiment, right?


@valeriojr - This is a really old question (2012) things change quickly in the tech world!

Some corrections are do here: First the way the SATA standard was written only allowed older drives work in newer systems. So a SATA I (1.5 Gb/s) drive would work in either a SATA II (3.0 Gb/s) or SATA III (6.0 Gb/s) system.

As for a faster drive working in a slower system strictly by the standards its not compatible!

But! Many drive makers offer auto sense drives (vs fixed speed) like Samsung's 850 EVO which dial back the drives I/O to match the systems. Not all drives do this! You'll need to review the drives spec sheet to see what it offers.

OK, getting to your question 'Investment' I would say its worth it! Even a older SATA II system will get a vast improvement in performance. The only rub here is the latest Mac models won't have any means to use this drive internally you'll need to get a external case to recycle it if you get a newer box.

But, the larger drives do get costly! This is were a dual drive config is better (SSD & HDD) or going with a hybrid drive (SSHD) if you can't support a second drive in the system.
