2nd SSD in MBP?

Hello everyone,

I have an early 2011 13" MBP. I've added more memory and swapped the superdrive out for a Crucial M4 SSD.
My question is would there be any appreciable performance gains in swapping the remaining seagate HDD out for another solid state drive.
I realise there wouldn't be a speed increase since the os boots from the SSD but what about file transfers to and from external drives or perhaps temperature and possibly fan noise, would those decrease?

Thoughts/opinions welcome :)
 
Well obviously both would decrease.

Also if you carry your mac around often. It will lessen the risk of damaging the harddrive from moving it around.

Speeds would Increase as I'm sure you know.
 
Putting an SSD in the Optical bay doesn't work for most 2011 machines.

OWC had some success on some machines, but it seemed unpredictable. My late 2011 unit for example won't support an SDD in the optibay. It mostly works, but then stutters, slows down, and eventually hangs.
 
If it's that way around, and it works, he's very lucky! Looking at the testing OWC did, it seems they had most success with the 13" units, and least success with the 17's. Which sucks.

I'm surprised that should be the case. If the connections between the machine and the drives is the same I can't see why it wouldn't work (that could well be ignorance on my part).
I'll admit that I'd be a little sceptical about doing it had I read that before doing it but I've been very pleased with its success.
As for temp decreases after putting two SSD's in, I'm still unsure. The largest temperature increases I see (according to iStat) are when using final cut X and fan noise increases a huge amount. I can't see how a SSD would contribute to lowering that.
Thanks for your feedback :)
 
You would assume that a SATA-III port is a SATA-III port is a SATA-III port wouldn't you? Not really the case unfortunately. OWC went through all kinds of testing - including increasing things like the shielding in the optical bay.

It's just unworkable in mine - both my 17" and my 2011 15" too (now sold).

Minimal risk of that. All MacBooks with spinny drives have a G-sensor in the factory drive or on the logicboard (earlier machines)
