Pros: completely functional for my old desktop

Cons: none

Overall Review: On my old computer I used MediaTester v0.4.1.0 to check the quality of this usb stick and got the read speed is 77.14MB / s and write speed is 95.66MB / s. All sectors of the usb key have been validated. For this 128 GB key, MediaTester passed the media test successfully and recorded 128 143 851 520 Bytes of 128 144 375 808 Bytes total. Which leads me to say that this seller is selling a good product.

I purchased this product to add a 2nd sata drive to my laptop. I was amazed to see the ease that I had for its installation. It was wonderfully good. The speed of reading and writing is higher than that of my sata 3 hard drive. I am very satisfied.
