Q1：Why large-capacity file can not be written to more than 4GB flash drive?
A1：common disk format can be broadly divided into four types: FAT16, FAT32, NTFS, the exFAT. Different disk formats, to transfer a single file size will be limited. File system format as FAT16, a single transmission file size 2GB not exceed; file system format as FAT32, a single transmission file size can not exceed 4GB; single transfer files will be subject to a maximum partition capacity file system to NTFS format. If you have a greater capacity to file requirements, it is recommended that Microsoft's latest exFAT format can be used. exFAT in Windows VISTA SP1 later versions have a built-in, but would like to use this format, you need to install the Microsoft update package (No. KB955704 Windows XP normal download site http://support.microsoft.com/kb/ 955704 /), but please note that this update package applies only to Windows XP SP2 or SP3 version. Another when using the exFAT format, still need to pay attention to other multimedia devices (such as a digital camera or mobile phone) whether the synchronization support!
Q2：Why the same flash drive of RamMAX, early write fast, the newly bought very slow? Product failure or deterioration of the quality?
A2：Early Flash IC SLC type, but should the market demand for high-capacity product for small volume, most of all memory disc manufacturers shift to MLC Flash-based IC design conditions to overcome limited. MLC IC memory read speed of the disc quite the SLC Flash, but the write speed is indeed a little slower, the purely product characteristics dictates, is not a malfunction Oh!
Q3：USB 1.0, USB 1.1, USB 2.0 What's the difference?
A3：USB 1.0 is based on the transmission rate of 1.5 Mbps per second data; data transfer speed of the USB 1.1 interface can be per second to 12 Mbps; while the USB 2.0 interface is based on a 480 Mbps per second high-speed transmission of data. In other words, different transmission interface, will lead to a different data transfer speed.
