Anything specific?

Anything specific?

Model specifications. What technology it uses, do I need TRIM, what P/E will it support, etc.

That's pretty detailed...

This was the best I could find online and it's not even close to what you need...

I really don't know of a better place than system profiler - and you've been there already. I'm out of ideas.

These might help:

There are extra details you can find out from the terminal but I don't know how to do it for disks.

The SSD in rMBP is Samsung PM830, which is the OEM version of Samsung's SSD 830. TRIM is enabled by default because it's an Apple SSD.

Can you say that for all rMBPs?

No, some of them use a special Version of the OCZ Vertex </irony>.


Yes, all current MBPs (and I think even iMacs) use the Samsung SSDs.

Well here is a post where the OP has the same model name and says on the inside it's SanDisk with Samsung controller. https://forums.macrumors.com/threads/1498989/

I'm just not sure now.

Hmm, that's weird. Any way you could open the back cover of the rMBP and take a picture of the SSD? That would help a lot.

If the model starts with SD then it's a SanDisk SSD, not Samsung.

They use Samsung, SanDisk and Toshiba in the Retina.

Do you have any info on what specs it has?

Well they all support trim, as for the specs, I'm unsure. Given my basic knowledge about SanDisk - it could either be a Sandforce controller (which I **highly** doubt Apple would use), or a Marvell one.

Can you take off the back cover of the MBP and take a picture? I haven't seen a SanDisk SSD before so honestly I have no idea what specs it has, but if I get to see it I'm sure I'll be able to tell you all you want to know.

Another option is installing Windows and running a few tools, though that won't give as good idea as a picture would.

I don't have the screwdriver to open it with, it looks like a very specific type. What windows tools do you have in mind?

HD Sentinel can report lots of stuff (e.g. NAND if the firmware allows). You can also run AS-SSD and ATTO, the speeds should tell us if it's SandForce or something else.
