Diskuze k produktu:Kingston DataTraveler G4 8GB, žlutá
Rychlost
Rychlost je dost mizerná,mám to norm v usb 3 portu,a lítá to jak na houpačce jede to pár vteřin 8mb/s a pak to padne až na 4mb/s a zase na 7-8mb a tak pořád dokola
Rychlost
Nikde jsem zde nezjistil jaké jsou u této flashe rychlosti čtení a zápisu.
Může se někdo z CZC k tomu vyjádřit?
Rychlosti 8 GB verze
Formátována na výchozí FAT32 a 4096 b alokační jednotky a .... pořádná bída u zápisu!
USB 2.0
