Review on Sandisk Ultra Flair 128 GB Silver USB Flash Drive: Reliable and High-Speed Storage by Wiktor Lipski ᠌

Read speed is close to the declared 130Mb/s on USB 3.0; 125Mb/s on USB 2.0 also pleases; 37Mb/s that's not a fountain apparently; the controller overheats, and there is a dip in speed when writing a large file; the first 400-500MB are written. Pros: read speed is close to the declared 130Mb/s on USB 3.0; 125Mb/s on USB 2.0 also pleases; Pro Further, USB 3.0 can read at 40 Mb/s, whereas USB 2.0 can read at 20 Mb/s. Both USB 3.0 and USB 2.0 can write at 10 Mb/s. It takes around three megabytes per second to write a group of files that are each about a megabyte in size. Having these drawbacks: From the front, it appears that the flash drive is made entirely of metal with a small plastic eye. However, the back of the flash drive, which is hidden by the packaging, is composed of two thirds plastic. This significantly undermines the reliability image created by the product. If the casing were constructed entirely of metal, then the issue with overheating wouldn't have occurred till a little bit later:)
