very light weight perfect for travelling
the block color makes it look and feel luxurious for some USB colors like grey after plunging in and out a lot it will look damaged not the case for Sandisk's ultra curve black color as it doesn't;t look horrible with marks I think it looks more beautiful.

Works well
Gave me some trouble connecting initially, but a quick format (as all new flash drives do) prior to using should resolve any issues.Good product, lightweight and inconspicuous.

Compact and reliable USB stick designed to offer fast data transfer speeds and storage capacity
Positive: Many users praise the fast read speed (up to 100 MB/s), which makes file transfers faster than older USB drives. The compact size and durability are also highlighted, as well as the ease of use โ just plug it into any compatible device and start using it. The SanDisk SecureAccess software is another appreciated feature, as it provides a simple way to protect private files.Negative: A few users have noted that the write speed is slower than the read speed, which can be a bit frustrating for those transferring large files frequently. Some have also mentioned that the drive can feel a bit warm during extended use, though this is not a widespread issue.The SanDisk 64GB Ultra Curve USB 3.2 Flash Drive is a solid choice for those needing a fast, reliable, and portable storage solution. Its fast read speeds, 64GB capacity, and compact design make it a great option for transferring and storing files across multiple devices. While the write speeds may not be as fast as the read speeds, it still offers decent performance for everyday use. The added data protection via SanDisk SecureAccess is a valuable feature for anyone needing extra privacy for sensitive information. Overall, this USB stick provides excellent value for users looking for a balance of speed, capacity, and portability.

Good drive for backing up documents
Bought to back up some documents on my computer. Good size for a bunch of documents. My computer is old and slow so I cant really comment on how fast this flash drive works bc my computer moves at a turtle speed no matter what. Lol I do trust SanDisk brand though bc I have never had any problems with it.
