Recently, a large number of expanded U disks have reappeared in the arena. The author has to come to popularize the harm of these products, so as not to be deceived. What is a 65 yuan “1TB” U disk expansion disk: expansion disks are common in U disks, mainly because some “little geniuses” have modified the U disk master control information through software, so that the displayed capacity of the U disk is much larger than the actual capacity. It used to be 256MB/512MB to expand to 2GB/4GB, but now it is generally 64GB/128GB to expand to 1TB/2TB. Is the expansion disk useful? Many users think that the expansion disk is similar to virtual memory, but in fact, the logic and function of the two are completely different. Although virtual memory is called memory, it uses part of the hard disk space and can store some redundant data in physical memory, allowing the CPU to read data from physical memory more efficiently. At the same time, virtual memory can also carry some functions of physical memory, but the speed Much lower than the physical memory on the motherboard. Virtual memory can play an auxiliary role in physical memory, but the expansion disk has no benefit to the original U disk. It simply modifies the hardware information of the original U disk, how much the original U disk has, and the actual capacity after expansion.
