Is a type III SSD too fast for a MacBook Pro A1260?

Working on a MacBook Pro 4,1 A1260 that has an optical drive replacement caddy housing a 256GB Samsung 840 Evo.

This is a 2.5GHz Core 2 Duo machine that now crashes under load, especially when using Logic Pro X. I know this machine has a 1.5Gb/s Sata bus.

Is this SSDIII drive too fast for this architecture?

Will a Sata II work better? I'm having trouble even locating Sata I drives of reasonable size.

Lastly, what's the recommended position for the ssd. drive bay or caddy?

Answer this question I have this problem too

Is this a good question?

The only consequence of using a SATA III drive in a computer with a slower SATA bus is that you are limiting the top speeds of the SSD. It shouldn't be crashing your computer. in fact, SATA I SSDs are hard to come by nowadays since few people want to buy such archaic technology.

I'm interested as to why you installed the SSD in the optical drive slot - if i remember correctly, some Macbook Pros have a little trouble with SSDs in the optical drive SATA port. If you have a mechanical hard drive in the hard drive slot, try swapping them and seeing what happens.

If it still crashes, your problem isn't using a SATA III drive in a SATA I slot.

This is difficult for me to diagnose because there are several variables and the logs don't show anything directly pointing to the problem. I have a vague recollection of reading that a 6gb/s Type III mightn't clock down to the 1.5 speed depending on the controller…

It also had several Presonus Firepod 8 channel A/D converters firewired in, so there's that possibility.

Also, it became apparent the the cpu was reaching temps of over 200F under modest load. Took out the logic board to find the dreaded "macbook pro with too much thermal paste" problem. Arctic Silver 5'd it and it's running much cooler.

For the moment the ssd is removed because we needed a stable platform for live recording.

I put the ssd in the optical slot simply because it was easiest and there was some question of putting the hot platter drive up near the heat pipe and of perhaps changing the airflow characteristics. But you're right, it'd be a good test to swap them.

No. Buy it, install it.

Macbook Pro's of that era have a SATA I bus.

New SATA III drives are backward compatible!

I understand that today - SATA III SSD's are cheaper than an old SATA I drive, due to increased production of the new models!

You can do it! I did the same thing: 128GB Kingston SSD to replace the old - and very slow - HDD in a Macbook Pro A1226! Working like a charm.

Good luck,

Dear Rusty, would you care to share the exact model of the SSD that works like a charm to you? I'm also trying to upgrade my old machine and I'm not sure that every SATA III can run at 1.5Gb/s.
