    You require SPEED or SPACE?
    4 out of 5 stars
    You require SPEED or SPACE?
    Your initial requirement for upgrading any SSD would be more space. Of course, you'd like the added speed bump, but then again, you were already there. So, when it comes to space, yes! Good choice, all offer the same space increments.However, when it comes to speed? I would not recommend this drive if you want a massive upgrade. I have installed this on a MacBook Pro Retina 15 10,1 (the first ever retina released). The Samsung Flash installed in it wrote at about 350mb/s and read at around 400mb/s. You can say that JetDrive 725 probably boosted things by around 30mb. I've attached a screenshot. Sadly, lost my original one for the samsung drive. You'll have to take my word for this.I did not re-format the drive. I restored it from a Time Machine backup which probably could explain the lack of speed improvement.The installation was really simple, so if that is what is deterring you from buying, don't be stupid. They have a good webpage explaining everything with a video, follow that. The 13incher is a bit more painful than the 15in MacBook.The added bonus is the external enclosure being added. Allows for some great high-speed transfers there via USB. Small enough to fit in a pocket.So, my verdict. If I were to upgrade to 1TB would I go JetDrive? Probably... unless I get something for the same price with a better read/write speed.(Note) A buddy just bought his 13in Retina, his read write (samsung drive included with purchase) is around 650mb/s. No idea what causes it, probably newer internals.Hope this allows you to make a conscious buying decision. I really required a space improvement, so I bought this. Had it been for speed, probably not. Do your research, check OWC's drive, don't take their read write speeds, find out someone else's experience with it.

      Mar 2015. This is a wonderful product and if you need the space, I highly recommend it along with the other reviewers who thoroughly cover it's excellent performance, value, simplicity of installation - watch the video - and well thought out features including a nice case for your old SSD drive.

      Transcend has really focused on the MacBookPro market and done a fantastic job. Unfortunately, when you first investigate this drive and try to decide if it is a good choice, you will immediately read that Yosemite does not support something called TRIM on third party SSD drives like the Transcend JetDrive. This is confusing and caused me to do a lot of research.

      <Update Note: as of July 2015, Oskar Groth was able resolve the TRIM issue with third party drives as he explains on his website.
      https://www.cindori.org/safely-enable-trim-on-yosemite-and-el-capitan/ Oskar explains that new functionality from Apple made this possible. and I have downloaded his Disk Sensei application and can verify that Trim now works with no complications. Disk Sensei is also a nice application with other useful features. The text below is interesting, so even though the TRIM issue is now resolved I'm leaving it as it describes the issue and may help someone in the future if the TRIM issue returns with future Apple updates.>

      Top Level Summary: if you need the space, I think the TRIM issue shouldn't be a factor in your decision.
      TRIM is desirable, but I think you can safely buy this drive and not worry about TRIM. If you are interested in the benefits of TRIM, the rest of this note explains how to safely and simply enable TRIM periodically. The best news is that even if you want the benefits of TRIM, there is no urgency as you can always run TRIM later whenever you want to.

      Two quick notes that I think add to the discussion:
      1) Availability - it is probably wise to buy sooner rather than later because in it's most recent products, Apple is moving from SSD's with the SATA III interface to SSD's with the PCIe interface. The very specific nature of Transcend JetDrive means that it addresses a limited market: a SATA III interface SSD that will fit in a MacBookPro. The newest MacBookPro Retina now uses an SSD with a PCIe interface. As a result, if you are interested in upgrading the size of your MacBookPro SSD, it might be wise to buy this sooner rather than later, in case availability of a SATA III SSD that will fit in the MacBookPro becomes an issue as the PCIe SSD's become dominant in Apple's product line.

      2) As others have pointed out, TRIM is important but not critical. You can buy this drive and not worry about TRIM. However, if you want to have the benefits of TRIM, a small amount of effort makes it possible. Unfortunately, Transcend can't supply this directly, but you can do it yourself quite easily.

      Long discussion on TRIM below:
      A1. Apple uses TRIM
      Mavericks and Yosemite continuously run TRIM on Apple supplied SSD's. However, for obvious but unwise business reasons, Apple will not run TRIM on third party SSD's. Hence to run TRIM on the JetDrive 725 will take you some additional steps. However, it is only necessary to run TRIM when you notice your SSD performance seems slow. This would likely happen only after a few months of normal use or when the drive starts to become full. In that case, with a small amount of effort, TRIM can be run as a batch process that TRIM's the entire disk. If you don't mind an occasional inconvenience, you can easily run it periodically as part of your normal usage patterns (once a month? twice a year?).

      A2. 960GB of Laptop Space is Great
      In my opinion, TRIM is probably not a reason to hesitate on purchasing this drive if you want the additional space. For example, if you use your MacBookPro for digital photography, a 960GB drive is extremely nice. With a Nikon D800 a "typical" photo shoot event runs me about 10 - 20 GB of raw photos before I can select out the photos that seem best. Also, I use Google Nik software filters, and because they use the lossless but horribly inefficient TIFF format, they create a 100MB copy of every one of the photos they touch.

      B1. TRIM is Important, Not Critical
      TRIM is important but it isn't critical. Even though Mavericks and Yosemite run TRIM continuously on Apple supplied SSD's, because of the nature of the kind of problem that TRIM is designed to solve, it doesn't have to run continuously. TRIM is only necessary if you notice your SSD performance isn't as good as when you first installed it.

      B2. TRIM using an Alternate Boot Disk - booting off of an SDHC or SDXC Flash drive
      Once TRIM is enabled, as Allan Marcus pointed out in his Mac OS X Hints post, it can be run in batch mode by Apple Disk Utility under the Repair Volume command. Note: Disk Utility cannot run TRIM without first enabling TRIM, so you have two tasks: create an alternate boot disk and then enabling TRIM on that boot disk.

      With a TRIM enabled Yosemite running on an inexpensive SDHC or SDXC Flash Drive, it is simple to use the normal Mac interface to occasionally (once a month? Twice a year?) run TRIM. Running TRIM periodically with Disk Utility requires an alternate boot drive, because Disk Utility unmounts the disk it is working on. It is possible to use the Apple Recovery Partition and "single user mode" to try to work around this, but it's not worth it. Keeping an inexpensive SDXC backup copy of your OS and Applications is probably a good practice anyway.

      B3. Copying Your OS and Applications to a Flash Drive
      One way to have the benefits of TRIM is to copy your Yosemite OS and Applications to an SD card flash drive. For that purpose, I used a 128 GB flash drive and Carbon Copy Cloner. My OS and Applications would easily fit within 64GB, but I used a 128GB card because I wanted the extra space and I liked the JetDriveLite form factor.

      B4. Once you have a bootable flash drive - Sequence to run a batch TRIM operation
      0) backup your entire JetDrive. This is always a good idea because SSD's do fail. Make sure your MacBookPro is plugged into working AC power and your battery is already fully charged in case of a power outage. The steps you will follow are very benign, but backing up is always a good practice whenever you "touch" a disk.
      1) set your startup volume to be the MacOS you copied onto a SDHC or SDXC flash drive and reboot
      2) download (cindori.org Trim Enabler $10) and install ( this will install on your flash drive)
      3) enable TRIM using the convenient TRIM Enabler control panel,
      4) run Disk Utility to TRIM your drive - Open Disk Utility. Select your drive on the left pane, Click "Repair Disk."
      -- Is it dangerous to run Repair Disk on a healthy disk? No. Not unless you have a power interruption, so use AC power and run repair disk when your battery is fully charged.
      -- There are two philosophies: "don't fix what's not broken," and preventative care. Because filesystems are entirely deterministic, I think preventative care is the better choice. In principle, a Repair Disk operation can only discover inconsistencies, it cannot cause them. My experience from rotating platter HDD's includes filesystem inconsistencies ("B-trees" or mismatches in the numbers of allocated blocks) which were repaired. In at least two cases on old HDD's I needed Drive Genius to rebuild the directory table. In those cases I only lost one or two files, not the entire data set. My experience with SSD's is limited, but I have not seen those kind of errors on any SSD's I've used. I've had an Apple supplied SSD fail completely in my MacBookPro 15" Retina Early 2013, but luckily, I had a backup.
      -- So, unless a power interruption occurs (working AC power is important), repairing a healthy disk filesystem is a benign process.
      -- If you are unlucky enough to have major problems, the Repair operation may abort. If that happens, you need to switch your efforts from trying to get TRIM to run, to fixing the filesystem data on your SSD. Drive Genius is very useful in this case if you want to fix it yourself, but if not, take everything in to an Apple store or other experienced computer professional. If even Drive Genius is unsuccessful, you can always reformat your laptop SSD and restore from your backup, however in this case you may have an unreliable SSD and you might want to replace it.

      5) toward the end of Repair Disk processing, you will see in the log the line "Trimming unused blocks"
      -- if you don't see that, then TRIM wasn't enabled and you need to check the TRIM Enabler control panel again to be sure you enabled TRIM.
      -- also, you can check "About This Mac" / "System Report" / "SATA/SATA Express" and look for "TRIM Support"
      -- If you install the Transcend utility, JetDriveToolbox, be aware that it is unintentionally misleading. Even when TRIM is not enabled in the MacOS, under "DRIVE" it says "Trim Command Supported" but that refers to the SSD controller in the JetDrive - not the full OS - so you can't use that to judge the status of TRIM on your computer.
      6) when Repair Disk is completed, disable TRIM,
      -- this last step is important. you need to disable TRIM using the convenient TRIM Enabler control panel
      -- if you forget, it's not terrible, but you are leaving your system a little more vulnerable
      -- also, other users have reported in the forums a subtle result from "turning off" the Apple "signed kernel" protection. If you haven't used a clean install to put Yosemite on your computer ( I almost never use clean install), you might have old and incompatible MacOS extensions in your System folder. When Trim Enabler has enabled TRIM, it also changes a setting in the laptop nvram that tells Yosemite to ignore the "signed kernel" requirement. If you forget to disable TRIM, those old extensions will load and may cause subtle problems in other programs (like Airplay shows video but not audio). This is unlikely, but it did show up in some of the forums.
      7) set your JetDrive 725 as the startup volume and reboot
      You are done. You can perform this sequence every now and then as a preventative measure or just wait until you think you are getting poor write performance out of your SSD.

      Finally, you don't have to run TRIM if you never notice your SSD performance isn't as good as when you bought it. Technically TRIM does help SSD "wear," but SSD manufacturers do not rely on TRIM for their longevity. In any event, it is absolutely not critical to run TRIM frequently, so you truly don't have to worry about TRIM unless you notice a performance problem .

      As cited by Rich in the Amazon Q&A section, the issues surrounding third party SSD's, Yosemite, and TRIM are explained in detail on http://www.cindori.org/trim-enabler-and-yosemite/ by Oskar Groth. This is well worth reading if you are interested.

      B6. Enabling TRIM for Third Party SSD's - What is TRIM and its importance?
      TRIM is an important capability and I wish Apple's policy on third party SSD solutions did not make this a concern. However, for anyone considering the wonderful Transcend JetDrive product and concerned about the question of TRIM, as I explained above, I am convinced that it is possible to run TRIM without a major inconvenience or risk. TRIM is "not required," but because an SSD write operation requires an earlier erase, it means that over time an SSD with normal activity will start to have lots of blocks of data that have been "deleted" in the MacOS, but not erased on the SSD by the SSD controller.

      SSD's aren't designed around a specific filesystem, so the SSD controller isn't built to understand any of the specifics of the MacOS filesystem. Even though the allocation tables the MacOS uses to assign and de-assign (or "delete") the blocks used by a particular file are stored on the SSD, the controller itself can't read or understand the allocation tables and does not know which SSD blocks the OS has marked as "deleted" and hence, are ready to erase. That is why finding which blocks toTRIM must be an Operating System function, not an SSD controller function.

      Eventually, as the number of "un-erased but deleted" blocks increase, the MacOS will start to have a significant number of writes that occur on blocks that require an erase cycle first, and write performance will suffer significantly on those writes.

      There are interesting details in how an SSD works, and to some extent the SSD moves data around on its own for longevity purposes (http://en.wikipedia.org/wiki/Write_amplification). As a consequence of moving the data, the likelihood of having lots of "un-erased but deleted" blocks is reduced. For this reason, TRIM may not be as necessary, however, it is factually true that any system capable of running TRIM does - including Apple's MacBookPro implementation of SSD's in Mavericks and Yosemite.

      The trick is that Apple has made it "more difficult" to run TRIM on third party SSD drives in Yosemite because of a new security feature. Yosemite's default is to only boot from a "kernel" that is "signed." A "signed kernel" means that Apple can guarantee that it is more difficult for malware to corrupt the basic operating system. Whether this is a good feature or not can be debated, but it seems desirable to me as one more small step at fighting off potential attacks on your computer.

      It seems clear that TRIM is very useful for most people over time, and one important point is that because it is a filesystem function, it can be invoked as a batch operation using Apple's Disk Utility.

      B7. Example Disk Utility Log (command line - you can use the GUI)
      Specifically, if you enable TRIM (Trim Enabler from cindori.org is one method) and run the Apple Disk Utility and select Repair Volume, the Disk Utility will trim the unused/deleted blocks by commanding the SSD controller to erase the list of blocks it sends.

      The command line below runs diskutil on the JetDrive volume labeled "myDrive" and mounted in my alternate boot Flash OS as /Volumes/myDrive. My setup is slightly more complicated as I split my jetDrive into two partitions.

      It is a 5 Stars for now, since the JetDrive is working fine. But I am writing this because of the initial booting of this hard drive was a disaster. The installation went seamless, after I discovered that the directions are incorrect. To get to the Disk Utility you need to use the Command-R keys, not the option key went restarting.

      When I first started the Macbook with the Transcend JetDrive, it booted quickly and Safari opened. Then it quickly went dead. I rebooted and the MacBooks fans started roaring at top speed and then again when dead. I rebooted a couple of more times, and it never even when though the booting procedure before going dead. So my heart sank and felt like I had just wasted $500 and maybe more if my Macbook was been destroyed in the process.
      I decided to trying rebooting but with the old ssd drive which I had installed in the Transcend external drive casing. The Macbook booted up fine from the old drive. So at that point I was about ready to uninstall the Transcend card and install the old card. But ever hopeful I tried rebooting again with the Transcend and to my utter surprise, it booted up fine. It is now two days later and the Transcend has operated perfectly. I am getting great speeds on both the Transcend and the old ssd drive now installed in the Transcend casing.

      I am writing this because others might have similar experience. Why did the Transcend fail to work initially and then started working. I have no idea. The only thing I did after the initial failures of the Transcend to stay booted was the rebooting with the old ssd card from the USB drive. But it might be worth a try should you have problems like I did.

      I am hoping my luck continues with the Transcend. It really nice to have the extra hard drive space with such speed as well.

      The replacement of my old drive was easy and the software made the transitions easy. The old drive was useful as a flash drive.
      After installing the drive, I started to have the laptop lockup. However, I do not know if it was attributable to the software issues or the new drive.

      Very easy to install. You get everything you need to install it including all required tools. Much faster performance than the SSD that came with my MBP 15" Retina. Previous boot time was about 15 seconds now boots in 7 - 9 seconds. I was worried about the issue of trim support not being enabled and not getting the speed I expected. Speed test reveals hight 400 to low 500 read and write speeds.

      Awesome!

      I've had tis in my macbook pro for a few days and cannot get over the speed increase. my 2012 MBPR is like have a new mac. I'm running Yosemite 10.10.3 beta and using the new photos app with a library that is about 290 gb in size. Very fast scrolling and each RAW photo loads amazingly fast. Love it!!!

      Thoroughly satisfied customer!!
      I think the product is fantastic, its what my 3 1/2 year old MBP with maxed out RAM but only 250GB SSD needed. Colossal 960 GB SSD and a fantastic USB 3 enclosure for my previous hard drive.

      Product quality and packaging is great, the enclosure is sturdy. New SSD is faster than apple proprietary samsung hard drive. The process of swapping drives physically is straight forward and well explained. The problem I faced on 2 occasions was the inability to clone the new hard drive. For some reason OSX El Capitan (Version 10.11.3) would not let me clone the drive and there was ambiguity of enabling trim.

      I used a software called SUPERDUPER ( not kidding) to clone my SSD and then performed the straight forward swap.
      SSD is not cheap, but I was willing to pay to max out my MBP internal storage capacity.
      Very happy indeed.

      Install was simpler than expected, transfer was quick and I now have 4x the capacity of the original for an incredible price.
      I did have an issue that with many Yosemite uses I no longer have a recovery partition. I believe I had to use the Command-R keyboard combination during boot instead of just holding the Alt key. Hopefully Transcend can update their instructions to cover this. I have also imaged OSX drives using Carbon Copy Cloner and Super-Duper without issue in the past if the Command-R option doesn't work.
      Swapping it out took about 15 minutes but that's just due to the number of screws holding the case together and I didn't want to use my power screwdriver
