SanDisk Ultra Shift USB Flash Drive USB 3.0, 100MB/s R, 64GB

Faster and cheaper than others

Performance: Read speed: ~137 MB/s Write speed: ~56 MB/s Large files transfer smoothly, but write speeds drop when handling lots of small files.

Original and fine.

Good for the value

Heating issue is there and I can't transfer files which are of 4 gb Or upto 4 gb live movies or video.

I have been using this pendrive for some time. The performance is okay for daily use, but there are a few downsides. The reading and writing speeds are average — good enough for normal files like documents, songs, and movies, but not very fast for heavy transfers. I also noticed the pendrive heats up while transferring large files, which can be concerning. Another issue is the build quality. The case feels cheap, and the material flexes when pressed, which doesn’t give much confidence about durability. Pros: Compact and portable Works fine for light daily use Storage as advertised Cons: Heats up during transfers Average speed (not very fast) Cheap build quality, flexible case Verdict: Good for basic use at a budget price, but the heating issue and weak material quality make it less reliable for heavy or long-term usage.

The only thing good about the pendrive was that it was delivered properly packaged. Apart from that, it can't be used at all, as it's stuck on "write-only". There is no provision to get it replaced, unless you're willing to spend more on getting it couriered and exchanged. Didn't expect this from SanDisk. (or Amazon for not allowing a refund/replacement.)

Awesome product
