It does store the data well and does not have issues with corrupt files. The capacity is good (128GB) and the only real concern is how hot it gets. It certainly does the job of storing your pictures and videos just fine, and has fast storage.

Customers are mixed about the quality of the flash drive. Some mention it's a pretty good flash drive, perfect, and a great thumb drive to keep on you during the transition from USB-A. However, others say the write speed is really poor, disappointing, and the read-only state makes it difficult to write any new data or change old data.

Reviewed in the United States on January 5, 2024
While its compact size is a significant advantage, it's also a bit daunting. To ease my concerns about potential loss, I attached a bright lanyard to it for peace of mind. Despite this minor precaution, I absolutely adore this drive. If you own a MacBook with solely USB-C ports, this is a must-have accessory that complements the computer perfectly.
what I am really impressed with is the durability! this drive somehow fell into the bottom of the dishwasher and went through at least 2 full wash and heated dry cycles before I noticed it was there. I thought for sure the data was lost and it was going to be e-waste. was I wrong!
I let it dry out overnight and tried it in my phone and it still worked! I tried it in my laptop and it still worked! transfer speeds seemed fine (though I didnt benchmark before so I can't say whether they have degraded or not)!
I am not sure how much shorter it will last compared to one I didn't wash, but just that I was able to retrieve my data, even if it dies tomorrow, makes me impressed enough to only buy SanDisk drives from now on.
I don't recommend trying this at home, I'm sure SanDisk recommends keeping them dry...so ymmv if this happens to you...but if it's going to happen, make sure it's to a SanDisk drive like this one!
HOWEVER this is where I'm sorely disappointed. The read speeds are near advertised and acceptable, but the write speeds are far slower at about less than a third of what's advertised. Moreover, the drive gets concerningly hot, particularly when it is being used in Type C mode. However, both read and write speeds are a touch faster in Type C mode as well and makes me call into question the buses used to interface with the memory, if the drive really is USB 3.1. When I plug it into my computer, the disk label reads 3.0, so I'm not sure whether they marketed the information or labeled it incorrectly. Moreover, there was a rumour that this drive is actually a micro SD card slotted into a dual adapter they've rigged up, which I could believe due to the sad write performance of the drive. Not in the mood to crack it open and break it to find out, but I definitely will once it fails.
SanDisk has a reputation and it kinda makes me sad to see a product miss the advertised marks this badly. As someone in tech, I keep an eye on the specs and rely on them to be true to the device which is why it frustrates me so much when a legitimate company makes mistakes and flat out lies like this. It makes me not want to give them money.
So why did I rate it 4 stars?
Because I'll be damned if this isn't the best flash drive I've owned, lies and all. I've been waiting for this type of drive for a while and most reputed companies haven't put one of them out yet, probably because the technology isn't good enough to have consistent enough quality in speed, which apparently SanDisk isn't bothered with ;) The convenience and the huge amount of storage for $20 on a drive that will actually work on all of my devices at a decent pace is too much of an allure to pass up. As long as the file isn't too big and I use this as a casual, day to day drive as most people will, this will work well enough. Moreover, the app is so dead simple and convenient for even the tech illiterate to use. May still want to attach to a cable for those 4K videos though.
Speeds in my pictures were collected using CrystalDiskMark. Faster speeds collected through USB-C Thunderbolt interface on same machine as the USB-A test, run on 3.1.
