Latest Version HDD SATA Cable Replacement 13"

Hi there,

@danj and @mayer and @itamazing and anyone else - I was hoping you can direct me to what is the latest SATA cable model for a 13" Macbook Pro 7,1 with SATA III capability enabled? I understand the newer cables are thicker and denser, so I am assuming a 2012 model cable would be retrospective for my Mac in question? I did see on the other posts that there is backward compatibility, but I am assuming this does not extend to the cables subject to a 15", is that correct?

Based on my research I've seen people saying the following:

821-1226-A = even older

821-1480-A = original --> been told some work and some don't?

821-2049-A = new

821-2480-A = does this exist? newer?

@mayer you mention part #604-07597 is the latest, is that correct? is that 821-1480-A?

So all in all, What is the LATEST cable part # in respect for a 13" with SATA III capability? Where would be the best place to buy? I'm based in Australia.

Appreciate the help and clarity guys!

Cheers

This can be confusing! ;-} You are referencing the manufactures part numbers not Apples part numbers. I use this cable MacBook Pro 13" Unibody (Mid 2012) Hard Drive Cable - Apple P/N 923-0104. Depending on the age of the system I might have a slight issue with one of the mounting screws which I need to do a bit of modification. Even still I place electricians tape on the uppercase where the cable rests.

The 15" model uses a different cable! Here again I use the newer 2012 model cable: MacBook Pro 15" Unibody (Mid 2012) Hard Drive Cable - Apple P/N 923-0084

To clarify the whole SATA II Vs SATA III issue, its the older 2010 models which Apple updated the systems firmware to enable it. But, the original cable these models had could not handle the higher data rate of SATA III (6.0 Gb/s) devices which is why they needed new cables.

But! All of the 13" & 15" models have a common issue with abrasion where the cable rubs against the uppercase rough aluminum which slowly sandpapers the cable! Which is why its important to place a strip of electricians tape to help protect it where the cable rests. A common issue is when people upgrade a HDD to a SSD and they encounter problems! This is a worn cable issue.

The 15" models have another issue where the mid-plane clips break allowing the bottom cover to press down on the cable damaging it! This is where its important the clip near the optical drive is the good one (if you have one) I also place some foam tape across the optical drives sheet metal to create a channel for the cable to rest in giving it some added protection.

Thanks Dan :) When you say Apple updated the systems firmware to "enable" it - you don't mean that SATA III is compatible with the the chipset that is in the Macbook 7,1, correct? SATA levels are fixed, aren't they not? Specs here: https://everymac.com/systems/apple/macbo... --> clearly SATA II?

In addition, is the cable you listed above (being a 2012 version) is backwards compatible with a 2010?

Based on your experience (I've done my research on the forums! ;) ] Do these MID-2010 models suffer from the Samsung 850 EVO dillemma, wherby the system fails, kernal panics etc? I reference Problems with Samsung 850 EVO SSD and https://discussions.apple.com/thread/647... (toward the later end of the thread).

Users seem to encounter issues with the 850 EVO but not the PRO, anecdotal but not personal empirical evidence points to more issues with the 850 EVO and its compatibility? and you have mentioned Samsung has better warranties than the Crucials, is the why you go with them? I have not come across any anectodal compatibility issues with the Crucials.. does this mean they are better and more optimally suited to the Mid-2010 Macbook Pro's?

Upon visual inspection (through the net) 821-2049-A seems to possess a larger cable base, would this not be indicative of higher throughputs and hence better suitability to handle a modern SSD like the 850 EVO? or is it the same as

923-0104, 923-0741, 821-1480-A, 821-2049-A, why then do Apple Part #'s differ?

What Part #/Manufacturer # of cable do you recommend for the 850 EVO and mid-2010 level of compatibility?

Appreciate the help.

Cheers!

Hi Dan,

I noticed in this thread --> Update of HDD to SSD --> you highlight that the Samsung 850 EVO is a Fixed SATA drive? was that a mistake?

and

in this thread -->Will this SSD fit in my Early 2008 polycarbonate MacBook? --> you highlight that you have seen mixed reviews when it comes to auto-sensing from (controller being Sandforce apparently) the Samsung's subject to the firmware it is on? what is the correct firmware?

Cheers

Boy! You're cleaning house ;-}

First at the time Samsung did not offer a full spec sheet so thats what we had to work from (it was a new drive). Once a spec sheet was published it was clear Samsung was still offering auto sense with their drives.

As for the firmware its long since been updated quite a few times. It's been awhile since I've worked on a polycarbonate MacBook. Most are not able to run the newer MacOS's.

Why are you bringing up these old comments?

Hi Dan,

Consider myself a little OCD when it comes to disparate views placed on this topic (both a curse and a blessing I guess :P)

But for a more altruistic purpose, I intended this post to be more a of a collection of the viewpoints summed up to its latest point, providing benefits to anyone who stumbles across this issue again.

But thank you for your input!! :D

As a side note, in respect to my build I've stumbled across the MCP89 AHCI Sata 2 controller in the Macbook 7,1 as its related issues to the various SSD's.

Samsung and Crucial both seem to come out on top in my research.
