FAT32 format: The default system format for 8GB flash drive is FAT32. FAT32 USB flash drive is widely applicable, such as in televisions, DVD players, vehicles, printers, embroidery machines, etc. Be patient if you have problems with system recognition. It may take some time for initial recognition, but it will happen. Please Note: 1.Features a standard USB 2.0 interface (typically identified by a black connector); 2.Typical transfer speeds: Write speed: 4–15 MB/s, Read speed: 10–30 MB/s; 3. The drive comes formatted in FAT32, which supports individual files up to 4GB. To transfer single files larger than 4GB, reformat the drive to exFAT; 4. The actual usable capacity will be approximately 90% of the advertised capacity. This is because storage manufacturers use the decimal system (1 GB = 1,000,000,000 bytes), while computers use the binary system (1 GB = 1,073,741,824 bytes). This difference is normal and expected and does not reflect a defective product or reduced storage capability. Widely Applicable: Compared with other external storage media, take CDs as an example, USB flash disk has obvious advantages in storage capacity, portability, etc., and the sound quality can also reach the level of CDs. Therefore, for modern car audio systems, using disk drives to play music is a better choice. The use of U disk is not limited by network connection, and data transmission and computer storage can be carried out without a network, which is particularly important in emergency situations or unstable network environments.
