Pros: I built a system without a hard drive and used this flash drive to boot and run linux. This system ran for six months, running prime95 without issues, until I finally broke down and bought an SSD.
Summary: Test performed once by Parkdale 2.94 free test software, on a USB3 port. Non-scientific (only done once). Seq. Write Speed: 18.3 MByte/sec Random QD32 765.7 kByte/sec, 191.4 IOPS, 5.22 ms Seq.
Pros: Speed appears fast
Cons: Cap is not attached to the device to prevent it's loss. There is not a ring on the device which would allow attachment to a key ring or badge holder type rope.
Summary: Seems built to last. Wish the end cap snapped on to the body a little more securely. Using dd on a Kubuntu 14.04 system and inserted into a USB3.0 port, my write speed was 39 MB/sec, and read speed was 116 MB/sec. I'm quite happy with the performance and capacity, especially considering the price.
Pros: Aluminum body, USB 3.0 compatible.
Cons: Cap can be removed a little too easily. No LED to indicate when the drive is being accessed.
