16g的内存怎么只有14g可用(16g内存为啥只有1.67g可用)

This is normal. This is like buying a 100 square meter house. Excluding the area occupied by walls. In other words, 95 square meters is the same. My 2G card is actually 1.8G, and my 8G card is actually 7.5G.

Normally, for storage devices such as U disks, mechanical hard disks, and memory cards, manufacturers calculate capacity based on 1000K=1M, while computers calculate capacity based on 1024K=1M, and the partition table is occupied. Space, reserved spare sectors, etc. will make the available capacity smaller than the nominal capacity. Generally, the available capacity = nominal capacity X0.93. Therefore, it is normal for a USB flash drive with a nominal capacity of 16G to have an actual capacity of only 14.4G.

Extended information

U disk, the full name is USB flash disk, and its English name is "USBflashdisk". It is a micro high-capacity mobile storage product that uses a USB interface and does not require a physical drive. It is connected to the computer through the USB interface to achieve plug-and-play.

The name U disk originally came from a new type of storage device produced by Netac Technology, called "U disk", which is connected using a USB interface. After the U disk is connected to the USB interface of the computer, the data in the U disk can be exchanged with the computer. Since Netac has registered patents for equipment with similar technology produced later, it can no longer be called "U disk" and is renamed the homophonic "U disk". Later, the name U disk became widely known because of its simplicity and ease of remembering, and it was one of the mobile storage devices. Now there are many U disks on the market that support multiple ports, namely three-way U disks (USB computer port, iOS Apple interface, Android interface)
