Saved a 2017 27" iMac!

The internal "Superdrive" of my iMac. I didn't want to disassemble my iMac to replace the hard drive. So, I decided to go external! The Sandisk G40 as the only drive is awesome! It boots and runs programs much faster than ever before! The G40 uses the Apple Thunderbolt 3 interface which has higher transfer speeds than Thunderbolt 3 and USB-C! My recent purchase is a backup drive. My original G40 has performed flawlessly for over 2 years! Higly recommended!

Awesome Drive for Windows

No issues on Windows. I downloaded Knoppix (live Linux DVD) and used Rufus to make a bootable USB drive. Booted from the USB drive to load Knoppix. Launched G-Parted and formatted the APFS drive to NTFS. Drive now recognized in Windows 11. You could also use G-Parted Live as well but I prefer Knoppix.

Fast and works perfectly

Love this SSD Drive. I bought it for my iMac and run my Lightroom Catalogue on it. I have had it a few weeks now and it has been blazing fast. A breeze to set up as it came formatted for my Mac OS.
