ATTENTION IPHONE 15 USERS
on May 5, 2025

Attention iPhone 15 users! I had to dig way too far in all these reviews to find the actual solution for how to use this with an iPhone - SanDisk PLEASE put this in the actual product description - to use this with an iPhone, go to this link and it gives you step by step to use with your Files app. No new apps needed, just knowledge of how to work with Files. You’re welcome! Save yourself hours of troubleshooting and potentially money wasted. It does work, you just need to follow these steps:

I would recommend this to a friend!

Ridiculously slow, impossible to set up, locks up
on April 18, 2024
Posted by: dfp!
1TB POC. I have used SanDisk flash drives for years. Read and write speeds are generally good.This is the WORST thumb drive I have ever had. Running MacOS Sonoma. Initially, I tried to load files and was getting messages that it would take a week or more. Terminated process, tried to reformat disk, disk utility app could not format, erase, etc. I had to format it from a PC. Still takes forever to load files. When I insert the drive, it takes forever for it to be recognized. Then, when I open it, no files appear for awhile. If I close the disk and try to eject it, my computer freezes with the color wheel of death. The only way to eject it sometimes is to shut my Mac down and even then it takes longer. Looking for a better alternative
No, I would not recommend this to a friend.

Hey guys i haven't bought this particular product but I have bought other 1tb flash drive and 18 external destopr harddrive.
My thougth are - for first glance you have couple of dual usb3.0 / usb c drives - could you like create a tables like why one is better than other and so forth. It feels like this would significantly simplify ones choosing process and i guess more happy customers.
