Ultra Shift 64GB, USB 3.0, Flash Drive, 100MB/s R, Pendrive, Black (SDCZ410-064G-I35)

very nice

Performance is good, many times reading speed will be 120-150 Mb/s, Writing speed is normal - 30-25 Mb/s Your device memory(Hdd) should be able to copy and transfer files to the speed this pendrive can perform and as well Bandwidth support by Motherboard, At the very first plugin -- I felt the heating issue of this pendrive, Then after this, only during read/write operation time, its temperature will be felt high, So leave it for sometime to cool down, its High temperature will calm down, Pen drive Data-sheet is saying its Higher temperature is 45°C-75°C, So Sandisk manufacturer is aware of its High temperature - So, May be, its Operating current is higher I feel plastic body housing could have been made from little more Hard Plastic

Value for money

Good product. Good quality and data transfer speed is excellent.

I ordered 3.0 with 128gb but got 3.2 version with 114 gb the speed is quite slow its maximum speed is around 20- 25mbps and the price is too high for this type of speed and I just transferred 15gh files but did not felt any heating issue .... Overall good experience but as it is plastic material you have to handle it with care

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.

Faster and cheaper than others

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.)
