SanDisk Extreme Portable SSD Mac Format Options
SanDisk Extreme SSDs have an exFAT (Extensible File Allocation Table) file system out of the box. That enables cross-platform compatibility, allowing macOS and Windows devices to write to folders and files.
However, you can format a SanDisk Extreme SSD for Mac with another file system. Here are your options:
| File System Format | System Compatibility | Decription |
| APFS (Apple File System) | macOS High Sierra (10.13) or newer | APFS is specifically designed for SSDs and is the default file system for macOS High Sierra and later versions. It offers improved performance, better space efficiency, and advanced features like snapshots, clones, and encryption. |
| Mac OS Extended (HFS+) | macOS Sierra (10.12) or older | The Hierarchical File System Plus is an older version of APFS with fewer features. If you have an older Mac that doesn't support APFS, you should use HFS+ (Mac OS Extended) instead. |
| MS-DOS (FAT) | Windows and macOS (the maximum disk size requirement of 32 GB) | FAT32 is an older file system widely used for its compatibility with various devices and operating systems, but limited by a maximum file size of 4GB and a partition size of 2TB. |
| exFAT | Windows and macOS (suitable for disks over 32 GB) | exFAT is a universal file system designed for large-capacity storage devices, providing seamless compatibility between Windows and macOS systems, making it ideal for external drives and file sharing. |
The APFS and Mac OS Extended file systems have multiple formats:
The journaled formats mean macOS keeps a change log, ensuring file system integrity. The case-sensitive option lets you name folders almost identically but keep them separate (e.g., Presentations and PRESENTATIONS). As for the encrypted APFS and HFS+, they enable you to encrypt and password-protect a volume.
As you can see in the screenshot above, many of these overlap. How can you choose the best SanDisk Extreme Portable SSD format for Mac? Let's find out.
What Is the Best SanDisk SSD Format for Mac?
If you want cross-platform compatibility for a SanDisk Extreme Portable SSD, the best format for Mac and Windows computers is exFAT for disks over 32 GB or MS-DOS (FAT) for lower-capacity SSDs.
If you wish to use your SanDisk SSD exclusively on a Mac device, the best format is APFS. APFS is optimized for Mac systems with solid-state drives (SSDs) like SanDisk SSDs and offers better performance, reliability, and security compared to older file systems.
However, APFS is compatible with macOS High Sierra (10.13) and later versions. If you're using an older version of macOS, HFS+ (Mac OS Extended) is the recommended file system for Mac.
As for other formats within these file systems, pick a suitable one depending on your encryption and folder-related case-sensitivity preferences.
Once you choose the desired file system, format your SanDisk SSD for Mac following the guide below.

FAQs About Formatting a Sandisk SSD for Mac
-
Is SanDisk SSD compatible with Mac?
Yes, SanDisk SSDs are compatible with Mac computers. However, to ensure optimal performance and compatibility, you may need to format the SSD using a Mac-compatible file system such as APFS (Apple File System) or HFS+ (Mac OS Extended). -
Should I format a new SanDisk SSD for Mac?
You don't need to format a new SanDisk SSD for Mac if you regularly switch between Mac and Windows devices. By default, SanDisk SSDs have an exFAT file system compatible with macOS and Windows. However, formatting it to the APFS (optimized for SSDs) or HFS+ (for older macOS versions) unlocks the possibility of encryption and folder-related case sensitivity. -
How can I make my SanDisk SSD work on a Mac?
Use Disk Utility to format your SanDisk SSD for Mac if you've previously changed its file system to the Windows-exclusive NTFS. Microsoft's proprietary NTFS isn't compatible with Mac devices, unlike the FAT and exFAT formats (available for Mac).
Final Words
Sandisk SSD is one of the best external SSDs for Mac. Whether you wish to format a SanDisk SSD for Mac devices after buying it or switching from a Windows PC, Mac's Disk Utility is your go-to solution. The same goes if you can't access your SSD due to a specific hardware or software problem requiring formatting the drive.
However, since formatting will wipe everything on your SSD, use data recovery software like Wondershare Recoverit to save data in another location.
