Warm tips for using Jostart USSD flash drive

• USB flash drive capacity description

Storage device manufacturers generally use 1000 as a conversion unit, i.e. 1GB=1000MB; Computer system use 1024 as a conversion unit, i.e. 1GB=1024MB, So the system recognizes capacity of the U disk is less than the manufacturer's nominal capacity. For example: Nominal capacity 128GB, actual capacity about 117GB; nominal capacity 256GB, actual capacity about 238GB, and so on. In addition under the different operating systems, system files also takes a small amount of space.

• About u disk heating phenomenon

When a USB flash drive is powered on, it transmits data, causing the electronic components inside the drive to heat up.Chip according to the current length of time, frequency of read and write operations, to read and write speed factors such as heat. Because metal has good thermal conductivity and heat dissipation, metal u disk heating is a normal phenomenon, not a quality problem. u disk chip can withstand the high temperature of 85?, will not be damaged by heat, please rest assured to use.

• About u disk read and write speed

The read and write speed of the USB flash drive is affected by many factors such as computer configuration, interface, file size, and so on. The test environment data of Jostart products comes from the laboratory. If you use a device that is lower than the configuration of the test environment to transfer files, or copy more file documents or pictures, the actual transfer speed will be lower than the nominal speed. The transmission speed of solid state products such as solid state USB flash drives/SSDS is affected by flash particles, so solid state products generally use firmware to make SLC buffers. A single copy of a file that is less than or equal to the SLC cache set capacity is very fast. SLC buffers typically account for only 20% of the total capacity. For example, for 1TB products, the SLC buffer is generally within 200GB, and a single copy of a file within 200GB is very fast. When a single copy exceeds this capacity, it may cause the backend to slow down. These are the results of Flash features. When the capacity of a single copy exceeds the cache capacity, and the copied files are small and fragmented, the speed is normal.

• Supports single file transfer larger than 4G

The default file system for USB flash drives is exFAT format, which supports single file transfers larger than 4G.Some mobile phones, cars and TV only support FAT32 format, just format the U disk into FAT32 format can be used normally.

• About the copy folder slower than copy a single file

When copying a single file, the system only needs to create an index. When copying a large number of fine folders, each file needs to be indexed, so it takes a long time. Multitasking also increases the load on your computer and slows it down
