<br />	Capacity flash memory products are usually shipped in accordance with 1MB = 1000KB, 1G = 1000MB computing, but the operating system using binary arithmetic 1MB = 1024KB, 1GB = 1024MB, so there are some differences between the display capacity and standard capacity memory products.
<br />This is calculation difference between manufacturer and our PC
<br />4GB =approximately 3.5-3.8GB
<br />8GB =approximately 7.2GB-7.5GB 
<br />16GB=approximately 14GB-15GB
<br />32GB=approximately 28GB-30GB
<br />64GB=approximately 58GB-59GB<p> <b><b><img src="https://contestimg.wish.com/api/webimage/5ae44602e114ef0d1f16bb6d-large.jpg" noproxy><img src="https://contestimg.wish.com/api/webimage/5ae44602e114ef0d1f16bb6d-2-orgin.jpg" noproxy><img src="https://contestimg.wish.com/api/webimage/5ae44602e114ef0d1f16bb6d-3-orgin.jpg" noproxy><img src="https://contestimg.wish.com/api/webimage/5ae44602e114ef0d1f16bb6d-4-orgin.jpg" noproxy><img src="https://contestimg.wish.com/api/webimage/5ae44602e114ef0d1f16bb6d-5-orgin.jpg" noproxy><img src="https://contestimg.wish.com/api/webimage/5ae44602e114ef0d1f16bb6d-6-orgin.jpg" noproxy><img src="https://contestimg.wish.com/api/webimage/5ae44602e114ef0d1f16bb6d-7-orgin.jpg></b></b></p>
