FAQs Of best external ssd drive for mac

Do I need to format an external SSD for Mac?

Yes. For best speed and compatibility, I format to APFS or Mac OS Extended (Journaled). APFS is ideal for SSDs and Time Machine on macOS Ventura and later.

Yes. I have booted macOS from external SSDs. You must install macOS on the drive and select it in Startup Disk settings. Use APFS and a USB 3.1 / USB-C connection for best results.
