iMac Compatibility & Upgrade Options (2013–2019)
This Apple proprietary 12+16 pin blade SSD is an excellent upgrade path for iMacs manufactured between Late 2013 and 2019. Upgrading an iMac requires removing the display panel and re-applying specialized adhesive strips.
27-inch iMac Models (Late 2013 – 2019)
-
Supported Models: Late 2013, Late 2014 (Retina 5K), Mid 2015 (Retina 5K), Late 2015 (Retina 5K), Mid 2017 (Retina 5K), and 2019 (Retina 5K).
-
Upgrade Notes: All 27-inch iMacs from this era feature the PCIe blade slot on the logic board. You can use this 1TB SSD to replace a small factory blade SSD or to upgrade the blade portion of an existing Fusion Drive setup to create a massive, high-speed primary boot drive.
21.5-inch iMac Models (Late 2013 – 2019)
-
Supported Models: Late 2013, Mid 2014, Late 2015 (Retina 4K and Non-Retina), Mid 2017 (Retina 4K and Non-Retina), and 2019 (Retina 4K).
-
Crucial Upgrade Note: For 21.5-inch models, the 12+16 pin PCIe connector is only present if the machine originally shipped from the factory with a Fusion Drive or a standalone SSD. If your 21.5-inch iMac was configured solely with a 2.5-inch mechanical hard drive (base model), the logic board lacks this connector, and this blade SSD cannot be installed.
Frequently Asked Questions (FAQs)
Q: Do I need an M.2 NVMe adapter to use this SSD? No. This is a genuine Apple/Samsung OEM drive featuring the exact proprietary 12+16 pin layout required by compatible Macs. It installs directly into the logic board without any aftermarket adapters.
Q: Can I put this in my PC or standard M.2 slot? No. This drive uses a unique 12+16 pin connector exclusive to Apple hardware. It will not physically fit or function in a standard PC M.2 NVMe or M.2 SATA slot.
Q: Will this work in a Late 2012 iMac? No. The Late 2012 iMac utilizes an older generation SATA-based blade connector. This PCIe 12+16 pin drive is only compatible with Late 2013 models and newer.
Q: I have a 21.5-inch iMac with a standard 1TB Hard Drive. Can I use this? If your 21.5-inch iMac came from the factory with only a standard spinning hard drive and not a Fusion Drive, the PCIe slot is entirely missing from your logic board. In this case, you must upgrade using a 2.5-inch SATA SSD instead.
Q: Do I need to install any special software for this to work? Because this is an original Apple OEM component, it requires no special drivers or firmware patches. macOS will natively recognize the drive, allow you to format it via Disk Utility, and automatically enable TRIM support for optimal lifespan and performance.
