FAQ
Q: What is a NAND flash memory chip?
A: A NAND flash memory chip is a non-volatile storage device, It is the core component of USB flash drives, SSDs, memory cards, and embedded storage devices (like our UDP MUDP Chip). NAND flash chips are compact, energy-efficient, and offer fast read/write speeds with 100,000+ erase/write cycles and 10+ years of data retention.
Q: ls SSD a NAND flash?
A: No, an SSD (Solid-State Drive) is not the same as a NAND flash memory chip, but NAND flash is the key component that powers SSDs.
Q: The USB cannot play on TV, car, or video player?
A: Please format the USB to the FAT32 file system, which is widely compatible with multimedia devices.
Q: An 8GB+ USB cannot store a single file larger than 4GB?
A: Format the USB and select the exFAT file system to support single large files.
Q: A fault is reported when plugging into a PC?
A: Re-format the USB on the computer to repair file system errors.
Q: The USB is not recognized when plugged in?
A: Try another USB socket and plug it in slowly to ensure a stable connection.Need to assemble the MUDP,UDP to usb flash houses,then the usb can be recogized.
Q: Why is the actual free space less than the marked capacity?
A: A small part of space is occupied by the main controller, and there is a calculation difference between decimal (manufacturer) and binary (system), which is normal for all USB products including top international brands.
