Questions & Answers
--Question 1 : Why I bought 16gb usb stick, but the actual usable capacity is only about 14.5gb?
Answer : Because the storage capacity calculation method of usb stick is different from that of computer operating system,some of the memory is used for USB formatting or other uses of computer devices,so the actual capacity of 16gb usb stick is 14.5gb-15.3gb.
--Question 2 : How about the speed of usb stick 16gb ?
Answer : They are all USB 2.0 ports, usb 2.0 read speed is 12-15mb/s, write speed is 5-8mb/s.Generally, lower capacity USB 2.0 write speed is slower than higher capacity USB 2.0. If you just use usb to deal daily files ( powerpoint, documents, pictures, music, etc), USB 2.0 will be sutable and economical. If you deal large files, we suggest you to choose USB 3.0 port, it will save your much time.
--Question 3 : Why can't 16gb USB Stick transfer single 5gb file?
(1) Answer : Reason: FAT32 format does not support a single file over 4gb.
Solution : Firstly,check out whether USB Stick is in FAT32 format. Then format the USB Stick into exFAT or NTFS format, after this you can transfer over 4gb files single time.
(2) Tips: FAT32 format has good compatibility, but does not support single files larger than 4G. so FAT32 format cannot store ISO images, high-definition videos, various graphic works files, etc. NTFS and exFAT formatted USB drives can store single files larger than 4GB. But NTFS format is easier to be damaged, and shorten the life of USB sticks.So it is suggset that format to exFAT when you need to store single files over 4gb.
