Transcend960GB JetDrive 720 SATAIII 6Gb/s Solid State Drive Upgrade Kit for MacBook Pro 13" with Retina Display, Late 2012 - Early 2013 (TS960GJDM720)

I bought this (960GB model) for my 2012 Retina MacBook Pro. It works GREAT. It is fast -- I did a sequential bit-for-bit transfer from my factory SSD to this over USB3 using ddrescue & System Rescue CD, and did ~450MB/s of writes to it practically the whole time; the copy was done in minutes! -- and TRIM is working on both OS X (trimforce) and Windows. I have experienced no weird slowdowns or issues with power management or sleep/wake. Everything is as it was before, except I now have way more storage!I also love that the kit comes with everything you need to migrate over to the new drive, including screwdrivers and a very nice aluminum USB3 enclosure for your old drive that you can continue to use as an external drive after you have finished your boot drive migration. Given how relatively spendy this drive is, a 5-year warranty puts me at ease, as does the fact that I know Transcend is a trustworthy brand that has been around for a while, so I'm pretty sure they aren't going anywhere and will still be around should I need help during those 5 years. Since there are now cheaper, alternative solutions for MacBooks with SATA-based flash storage, such as M.2/NGFF adapters and super-inexpensive standard M.2 SATA flash modules, these are important factors to take into account when weighing one's options. For an aging 2010 MacBook Air that I have whose internal storage I also needed to increase, I went the cheaper route, and that has been going fine... surprisingly well, even. But for my primary workhorse computer, the Pro, I think that I made the right choice to spend a little extra money to get something specifically built and tested for this machine, for that little extra peace of mind.The only thing I'm still on the fence about is the software that Transcend provides to monitor the health of the disk. It's very basic, which is fine, perhaps even desirable. But given how basic it is, and with no explanation of the purpose for them or the benefits they offer, it makes no sense that when you launch it, it insists on installing a handful of "Privileged Helper Tools." The names suggest that they may help with power save / sleep issues, but without those installed, I have zero issues, and even if there were issues, there should be no need to take care of that sort of thing in software...if there are problems, that should be addressed in firmware, not with privileged system extensions. So I take care to launch JetDrive Toolbox very rarely and immediately remove these extensions after closing it. It's possible that these helper tools are specifically made for the JetDrive Lite SD cards that Transcend also makes, but I'm not using one of those, so they shouldn't force me to install these extensions whenever I run their Toolbox.Finally, I'll mention that I bought the 720 model instead of the 725 even though I have a 15" rMBP. I knew I was taking a risk, but the 720 happened to be on sale at the time I made the purchase, and as a result I saved a significant enough chunk of cash that the potential savings outweighed any risk that it wouldn't work and I'd have to return it (which I determined was fairly minor after doing some research). Given the fact that Apple uses the *same* OEM part #s for SSDs between the 13" and 15" models from 2012 through early 2013, that Transcend offers two different sets of SKUs for 13" and 15" models made absolutely no sense to me when I first started looking into the product. As other reviewers here point out, it turns out that Transcend originally also only offered one part for both 13" and 15" models as well -- the 720 -- but the 720 was half-a-millimeter longer than the official Apple part, which apparently was a problem for a small subset of the 15" rMBPs that Apple shipped, where manufacturing tolerances for the space that the SSD fits in allowed for a variance of that much room! So Transcend re-designed the PCB to shave off that extra 0.5mm so that it would fit in *all* 15" rMBPs and released the updated version as the 725. When they originally communicated about this issue, they strongly implied that the 725 would *replace* the 720, since there is no reason that the 725 wouldn't also fit just fine in the 13" model. Instead, for reasons that I cannot fathom, they still sell the 720 and 725 side-by-side, and label the 720 as exclusively for the 13" and the 725 as exclusively for the 15". Boggles the mind. And it's definitely not the case that remaining 720s in the retail channel are just old-stock, because the solution to this problem (the 725) was released in 2014, and I can tell you that my particular 720 stick was manufactured in April of this year. I have to believe at this point that 720 sticks manufactured after the release of the 725 are actually identical to the 725 in every way (because why continue to manufacture and stock two subtly different products that are otherwise identical in every other way?), and my best guess is that Transcend just figured it was easier to continue to sell both, since older 720s in circulation may or may not fit in a given 15" rMBP, so this just reduces confusion in certain circumstances (but, as you can see, increases the confusion in others!). Of course, this is just FYI and YMMV, and I'm not saying you should do what I did. But I'd be willing to bet real money that the odds are extremely good that a JetDrive 720 manufactured within the last 1-1.5 years (so, the vast majority of them) will fit just fine in your 2012-2013 15" model, and a 725 will have zero problems fitting in any 2012-2013 13" machine.

I have a mid-2012 15" Retina MacBook Pro, model 10,1I bought the 960GB version to replace my stock Apple 512GB SSD, since I was almost out of space on that drive. After I ordered the drive, Transcend changed their compatibility details to exclude 15" Retina MacBook Pros, but I had no problems installing the SSD in my machine, thankfully!The bad news is that the installation instruction video and Quick Start Guide are woefully inadequate and it took me quite a bit of searching to figure out exactly how to clone my existing SSD to the external JetDrive before swapping it out into the Macbook Pro. I am running OS X Mavericks 10.9.3 and my original drive was FileVault encrypted. Here's how I went about my installation, hopefully this will save someone else a bunch of time and make it easier to perform! (Four stars for the crud instructions, otherwise I'm very happy with the product, so far!)Oh and BlackMagic Speed Test records write speeds of 415MB/s and read speeds of 450MB/s, so this is a nice, fast, large, if slightly costly, upgrade!Installation Instructions for OS X 10.9.3 users (with FileVault enabled on original SSD / HDD):1. Install the JetDrive into the external enclosure provided and plug in the enclosure to an empty USB slot2. Start the MacBook up, holding down Command + R. This will load the restore options. (This step wasted a good deal of my time)3. Click on Disk Utility4. Highlight Macintosh HD (or whatever your existing SSD / HDD is called)5. Click on Unlock in the menu bar, if your source drive is FileVault enabled. You cannot clone the drive while it is FileVault locked. (This step wasted a good deal of my time as well)6. Enter your password7. Click Restore with your source SSD / HDD selected (Macintosh HD by default)8. Drag "Transcend" to the Destination slot (you will now have your existing SSD / HDD chosen as the Source and the new Transcend drive chosen as the Destination)9. Click RestoreThe cloning process took about 40 mins for my nearly full 512GB Apple SSD to clone to the new JetDrive. After that it was just a matter of swapping out the new SSD for the old one and then a couple more steps...10. With the new drive installed, restart holding down Command + R again11. Click on Disk Utility12. Under the Disk Utility menu click on Startup Disk13. Select your new SSD, this should be the only option if you do not have any other drives plugged-in to your system, and restart the system (this step tells the OS to default to your new drive on startup every time, otherwise it wastes several seconds searching for your old HDD / SSD at startup before using the new drive to boot)14. Check if TRIM is enabled by clicking on the Apple menu, About this Mac, More Info, System Report, Click on SATA and check to see if it says "TRIM Support YES". If it does, you're good to go. If it doesn't...15. Go to [...] and dowload the app16. Run the app and flick the switch from Off to On17. Restart your MacBook and you're good to go!

I bought this drive as an upgrade to the 256GB Samsung SSD that came with by 2012 15" rMBP.The package contains everything you need. It includes 2x screw drivers with the relevant heads. I particularly like how the screwdrivers are magnetic which helps in removing the old screws.The drive is very easy to install and it took me about 10 minutes to do it all. It took far longer to restore everything from Time Machine.The drive seems to work well and doesn't suffer any slowdown when dealing with incompressible data, e.g. when FileVault is enabled.Running the BlackMagic disk test, the old Samsung scored 326MB/s write, 340MB/s read. This Transcend JetDrive scored 424MB/s write and 507MB/s read, so this is a pleasant surprise.This is an excellent upgrade as it's improved both capacity and speed, though I don't actually notice any difference in speed as the old drive was fast enough for my needs.edit:After 4 months of daily use (loads of VM work, building software, etc) I can say that my feelings about this drive is mixed. I ran into problems when I upgraded to Yosemite and enabled "TRIM" using Transcend's JetDrive toolbox. I had to wait initially for Transcend to update the JetDrive toolbox to support Yosemite. Then once it did and TRIM was enabled, I noticed a lot of instability and a number of times when the drive would fail to boot. Wiping the drive and restoring images from Time Machine did not help.Reinstalling everything manually and re-enabling TRIM also seemed to cause problems. However, fully reinstalling everything and not re-enabling TRIM appears to have solved my problems. I suspect that the changes to drivers in Yosemite (look up kext signing on the Internet) is at the root of this and the Transcend have not properly tested their drivers. So for now, I've not bothered with TRIM and have had no issues.I'm knocking off one star off the review for this, and I would have been a lot happier if Transcend had bothered to get their drivers approved and signed by Apple.

I'm delighted with this upgrade package from Transcend. This is a high quality replacement 480 GB SSD for Macbook Pro which was installed with ease. It has nearly doubled the storage space available AND given increased disk read/write speeds. My factory installed SSD (Sandisk 256GB) achieved speeds of c. 454 MB/s read, 390 MB/s write. This Transcend Jetdrive 720 (480GB) achieves speeds of 522 MB/s read, 437 MB/s write (BlackMagicDesign DiskSpeedTest). The System Report confirms that the drive is an Intel 7 Series Chipset with 6 Gigabit link speeds on the SATA/SATA Express device. TRIM support and SMART status are verified.The startup speed is slightly quicker when the System Preferences/Startup Disk is correctly selected. Make certain that you go to the Transcend support pages and view the correct video for the Macbook, Operating System and Jetdrive configuration that you have. Some reviews state that they cannot enable TRIM - but this is only the case when running 'old' versions of Mac OS. My install was with a mid-2013 Macbook Pro Retina 13", running Mac OSX 10.11.6, El Capitan. TRIM was enabled in the native operating system using the instructions provided by Transcend in their FAQ pages.Only one slight niggle. Transcend provide a P5 screwdriver (for Macbook bottom case cover) and T5 screwdriver for the internal battery adaptor screws. In my Mac, (MacBookPro10,2) the internal battery adaptor screws were T6!I purchased this 'Used' item from Amazon Warehouse deals for 2/3rds the retail price for new! The box had previously been opened/reselaed and there was some sticker residue on the original retail box. All the contents were perfect and the SSD had never been used. The full five year warranty still applies to my purchase. I was very happy with this deal.

I purchased this to upgrade my Mac Book Pro from 128Gb to the 960Gb of this drive. I did try and clone the drive as described but for some reason it wouldn't clone my Mac Book drive. But that was not an issue as i wanted to reformat anyway to give me a completely fresh install.I had already made a bootable USB of Yosemite for my iMac. I used a YouTube Video to go step by step to install, no issues there at all. plug in the USB drive, boot into the drive and away you go, within 10 mins i had a completely fresh install of yosemite and could start putting on all my programs.This was simple, works flawlessly and has transformed the way i use my MBP completely. Awesome Product best money I've ever spent

I love this little thing - not only did it transform my MBPr (I was always smuggling files around to make room!) but the fact that it provides a housing for your old drive to become a super fast USB3 external is brilliant - copies huge files in the blink of an eye - installation was relatively stress free (all the tools are provided which is fantastic) the only slight gripe was the the fit of the new drive (which basically looks like a big RAM chip) was fairly tight which gave me a bit of a cold sweat as I was trying to get it into place. Definitely recommended.EDIT - should have said unlike others I've had no problems with Yosemite whatsoever - I haven't altered any of the setting as others may have.

Got it today package contained everything I needed screwdrivers, manual, enclosure etc.Manual was in a zillion different languages and was tiny so I opted for a online guide instead.Took 5 mins to upgrade my wife's 256mb SSD and then 30mins to restore the data from the original SSD to the blank drive.High quality, easy upgrade.
