Verified Purchase:Yes
I record oral histories and use flash drives to deliver finished video projects to my customers. I could use 8gb flash drives in this pack if they were available. For larger video files, 16 gb and 32 gb flash drives are used.

Read/Write mode
on April 8, 2025
Posted by: Kjelle1900
I use it for Mp3-files in my car and it worked well. Then I decided to change Mp3-files so I deleted the files and started to download new ones and suddenly during the process it changed to read-only mode without I`ve done anything. Now I can`t use it because I don`t how to change it to write-mode again.
I hope you understand what I mean. My english is not perfect.

RUNS VERY HOT!
on March 2, 2025
Posted by: Swarley
Runs 130 degrees F! Trying to remove it from port will burn your fingers.
After it heats up, performance drops off.
Response from SanDiskBy SM OLS, May 12, 2025
Sorry to hear about the overheating issue-130°F is definitely higher than normal for regular use. Performance throttling can occur if the drive gets too hot, but it should not be unsafe to handle. Please unplug the drive and contact our support team at: https://support-en.sandisk.com/app/askweb so we can investigate and assist you further.

Plastic
on November 28, 2024
Posted by: nobler
My favorite "thumb drives" are the old USB2 Cruzer Fit. Metal frame, and a place for a lanyard (or just a loop of fishing line) which is part of the metal case, so when you pull it out, it doesn't come apart. These new ones stick out too far, and they are plastic (not durable). By comparison, the Samsung "fit" drives are HUGE, but they are metal and I have not had any problems with them. So SanDisk, bring back the form factor of the old USB2 Cruzer Fit units and I might buy some.
No, I would not recommend this to a friend.

Love the size but putting files on drive takes forever. 3-4 days for a 1gb file. With brand new Mac Studio 64g memory M2 ultra. What good is have a 512gb thumb drive it it takes months just to put like 200gb on.

Can't use in a projector.

Posted by: Kipp
I bought this to store movies on and use in my projector for the kids while camping. My projector does not even recognize it's plugged in therefore nothing happens . Waste of money if I can't use it for movies in a projector!
