Customer Ratings & Reviews

I purchased it in January 2019 and it wasn’t working properly in May 2019. Company gives 5 years warranty and there were issues within 4 months. I could not return or claim warranty at Best Buy. I had to send it to San Disk. Their customer service is very lousy. Takes at least 3 weeks for replacement.

Not yet used - purchased as a backup for my ring doorbell.

I have used the before, the 128 was a really good price, i'm not sure when I will get around to opening it.

SanDisk has certainly taking a step backward with build quality on this item. I had the outer shell break from just being in my pocket on one of them. I'm babying the other one in hopes that it last a few months. I'm very disappointed with the build quality and won't be purchasing any more in the future unless they get back to their high standards of the past.

This is no better or worse than other flash drives I have purchased

Good flash drive though I'm not sure how durable it will be.

Overheats and is difficult to remove since it gets so hot. Was afraid it was going to damage my computer.

I’m using this on my Xbox one s and it works as it’s suppose to. However, transferring games from internal to this is a eye gouging process. It’s simply too slow for my lack of patience.

This very tiny thumb stick flash drive doesn't look durable.

This worked well, for a time. I used this in my car for music and audio-books. It died after 1 year. Not recognizable by computer or car.

The stick worked great and then it failed. Replaced under warrenty.

Stopped working after a week for some reason. Going to return it.

This thing gets ridiculously hot and then starts with the disconnects. Can’t recommend this to anyone!

turned out to be kinda useless...................................

Build quality is made by cheaper plastic. Not recommended

Good quality flash drive, not worth it for full price. Wait for sale.

This item is fast. I moved several large files and there was about a 10 times increase in speed over the old 2.0 USB’s. An example was a Thunderbird mail folder. This is typically a large file in the order of 8 GB and normally can take 20-30 minutes to copy. This flash drive was done in about 3 minutes. I was very pleased with the small size which will fit easily in your pocket. Put it in a small baggy to protect it from dust and you’re good to go. I noticed folks concerned about heat. I tried to move tons of data and it never got warm enough to concern me in the slightest. The front portion that is in the machine was warmer and depending on your computer this could get more or less warm. I used an Acer laptop with an SSD so the fan wasn’t running much to provide inside the box cooling like it would with an HDD – points are even without a cooling fan it was staying cool enough and it didn’t trip the fan by adding extra heat. In any event this is good news since the tiny USB was not creating much heat that didn’t get dissipated naturally. I also tried the new SanDisk cloud backup app for USB drives called Flashback, which comes free with this little flash drive. My flash drives can get lost sometimes and now I have the content saved. I really loved this app and will use it on all my PC’s. It will automatically create cloud backup for any flash drives you plug in. Now without remembering to do it, you are backing up your USB flash drives to the cloud. It will assign a location for each flash drive and will also ‘automagically’ divide the files based on type – for example photos, Excel files, documents etc. Someone has come up with a great app here. Try it you will love it also. I do highly recommend this little (but big at 128 GB) wonder and also the free app.

So buying it I thought it was a normal flash drive but it is a back up vault system and have had issue with the size of the files I have tried to copy to it. Not sure I think that were trying to make something secure but that was not how I thought it was going to work when I bought it.

Tried to transfer a 1 gb file to the drive. It overheated after about 500 mb and came to a halt; wouldn't proceed again until the drive had cooled down, which took quite a while. This happened every time for several attempts.

First thing to be noted is just how great I have found the sandisk brand to be. As a semi professional photographer, I have over two dozen sandisk storage products and not once have I been let down by any of them. Between the reliability and performance sandisk has given me over the years, they have made themselves the brand I now use exclusively. First thing I noticed when opening up this flash drive is just how ridiculously small it is. It really is nearly identical in size as a USB receiver for a wireless keyboard or mouse. I see the small size as a positive for someone like myself who carries many different items in my camera bag and/or accessory bag and I need all the space I can get. And since this flash drive has a small hook on it, I can easily attach it to a key-chain or other accessory. This is my first USB 3.1 device and I regularly transfer photos and videos between memory cards, flash drives, and hard drives. However there is a noticeable difference when transferring on this 3.1 device compared to a 3.0 and especially a 2.0. Although the transfer speed of this flash drive is impressive, perhaps the most impressive feature is the new sandisk flashback feature. As someone who has personally lost a 128gb flash drive that had about...120gb of photos and videos on it...I know how frustrating it can be to lose a storage device of any kind. Luckily I had not formatted my memory cards yet, but it was still extremely frustrating to lose a device that had so much stored on it. Sandisk’s new feature of cloud storage automatically backing up for you as transfer to the flash drive is extremely helpful. I have a feeling that that feature will be a lifesaver for many people including but not limited to students, artists, and content creators. All in all a great product that I would highly recommend to anyone.
