Review on Aiibe 5-Pack 16GB USB Flash Drive - Reliable Flash Disk Memory Stick with 💾 LED Light (16G, 5 Colors: Black, Red, Cyan, Green, Purple) - USB 2.0 Thumb Drive by Aaron Ward

Out of 5, 1 was DOA. During a test with CrystalDiskMark, it could only do sequential reads, but not sequential writes. When this was reported, the vendor offered a partial refund, roughly equivalent to the cost of a USB drive. In terms of performance, the average sequential read speed is 125 MB/s and the average sequential write speed is 25 MB/s. Reading is fast but writing is ok. The recording is comparable to a class 10 SD card. It should also be noted that the speed test cannot be fully performed with the PC front panel, which is a bus-power configuration. Using a self-powered USB hub passed the speed test with no issues. As a result, the USB stick consumes enough power quickly in sustain mode.
