SanDisk Ultra 128GB USB Type-C Flash Drive

Bought four of these flash drives for use with my iMac 24” 2021 model. Very fast data transfer compared to my USB-A flash drives. But then I use them for photo storage; backup of Pages files, Numbers files, Quicken files. I don’t transfer huge files like movies, games, etc. So, I can’t attest to their speed under those conditions. In order to use the USB-A flash drives on the 2021 iMac, adapters are required because the computer is equipped with ports that accept only USB-C style connections. These flash drives are comparable in cost to adapters. Just made sense to make the switch to the USB-C flash drives.

The unit I purchased must have been defective. I plugged it into my computer and it could not be formatted. I assumed it just wasn't seated properly, so I hit the eject button, unplugged it, and noticed it was quite warm... almost hot, which worried me. I plugged it back in, this time directly into my pc instead of my dock and made sure it was completely seated. I tried to format again. No luck. I tried once more for good measure, and still no luck. When I went to take it out again, it was EXTREMELY hot. Hot enough where now 45 minutes after the incident I can still feel where my thumb made contact with it while removing it (though there is no visible burn). I ended up returning it immediately and getting a regular USB A flash drive, which is working fine.

Compact, sturdy, and worked exactly how we needed it to. Great price, too! It was only $2 more than the one half its size, so we opted for the 128GB. It's a little hard to push in due to the way it can collapse into itself, but I'd rather have that than let the connector sit out all the time. We needed a Type-C to transfer a large amount of data from 2 laptops, and this did the job perfectly.

I bought this device for the iPad Pro to add more memory capacity. But in trying to use it the C Flash drive would get so hot that it would almost burn my fingers when I would unplug it from my iPad Pro. It would also loose what was stored on it as well. I took it back to Best Buy and exchanged it for a regular USB drive and have been very happy with it.

The tab used to push out the USB connector can be a little difficult to handle, but it can also be left open if it proves too hard to regularly use. The read light is helpful but may not be visible depending on which direction the device is inserted. The device is a little long but the added handle for hanging it from a key fob or strap is useful.
