Is this really a Kingston product

USB 3.0 is here that this to some USB 3.0 ports is detected part, but not as I unfortunately had to find at each ... The available storage capacity is approximately 58 billion bytes and a few Crushed (NTFS, FAT32) below the usual manufacturer "standards" of 1kB = 1000 bytes. Write speed: just beginning really great, but then reduced quickly to 10-15MB. When size clearly too little. Only the reading speed with about 60MB could satisfy. With this product Kingston has done no favors!
