This category contains SSDs for Apple computers: upgrade kits and drives for Macs where you want more storage or need to replace an older drive. Most of the models come from OWC, and there is also one SanDisk product. Before buying, check your Mac model and year, because Apple used different storage connectors across generations.
How to choose an SSD for a Mac
Model compatibility. Start with the exact Mac model and year of manufacture. MacBook Air, MacBook Pro, iMac, Mac mini and Mac Pro generations have used different storage connectors, so the same drive will not fit them all. You can find the model details under About This Mac.
Connector and form factor. Many Macs made before the move to Apple silicon had a proprietary Apple storage connector, so an older machine often needs a drive made specifically for it, or an adapter. Some models use a standard M.2 NVMe or 2.5-inch SATA format. Check the product description to see which models and years a drive supports.
Internal or external. In most newer Macs with Apple silicon the storage is soldered to the board and cannot be replaced, so extra space has to come from an external SSD connected over USB or Thunderbolt. An internal drive makes sense only when your model allows the swap.
Capacity. For the operating system, apps and everyday files, 500 GB to 1 TB is often enough. Video editing, large photo libraries and virtual machines call for 2 TB or more. It is wise to keep at least a fifth of the drive free so that it keeps running smoothly.
Speed and interface. NVMe drives are generally several times faster than SATA, but the Mac's own interface limits what you actually get. With an external drive the connection matters too: Thunderbolt carries considerably more data than standard USB.
Brands we carry
- OWC: known for Mac upgrade solutions, meaning drives and kits made for specific generations of Apple computers, some of which can be installed in an older MacBook, iMac or Mac Pro.
- SanDisk: known for memory cards, USB flash drives and portable SSDs, which can be connected to a Mac as extra external storage.
Frequently asked questions
Can the SSD be replaced in any Mac?
No, it depends on the model. Many older Macs allow the drive to be replaced, while newer models with Apple silicon usually have storage soldered to the board. Check your Mac model and year first, then choose a drive.
How much SSD capacity does a Mac need?
For everyday use, 500 GB or 1 TB is usually enough. If you work with video, large projects or virtual machines, 2 TB or more is a safer choice. Leave some headroom, because a nearly full drive slows down.
Is an internal or external SSD better for a Mac?
If your Mac allows the internal drive to be replaced, an internal SSD is more convenient because it needs no extra cables. If the storage is soldered, an external SSD is the only way to add space. It is also handy when you need to carry files between several computers.
Do I need to reinstall macOS after replacing the SSD?
Yes, a new drive is empty, so you need to install macOS again or restore your content from a backup. You can use a Time Machine backup or a clone of the old drive for this. Save your important files before swapping the drive.
