Not bad!. Cannot be compared to anything else as this is my first USB 3.0 stick. I had to do some BIOS, driver and Asus USB Turbo settings to get the seg test. 102 reads/50.58 writes. However, it is fast enough for most applications. I was able to transfer a 2GB ISO file in 65 seconds. For reference, my Kingston USB 2.0 drive scored 23.52 reads / 5.53 writes. Can't comment on durability as I've only just received it, but I've rarely had USB sticks break. ---CrystalDiskMark 3.0.4 x64 (C)
