Based on internal testing; performance may vary depending upon host device, usage conditions, drive capacity, and other factors. USB 3.0 port required.
About capacity:
16GB=approximately 14GB-15GB
32GB=approximately 28GB-30GB
64GB=approximately 58GB-60GB
128GB=approximately 115GB-119GB
200GB=approximately 182GB-186GB
256GB=approximately 230GB-238GB
512GB=approximately 460GB-476GB
1MB=1000KB.
Flash memory vendors are using decimal arithmetic: 1MB = 1000KB, 1G = 1000MB calculated, but the operating system is using binary arithmetic: 1MB = 1024KB, 1GB = 1024MB. So there are some differences between display capacity and nominal capacity of flash memory products. However, this is allowed to exist. Please do not doubt his authenticity. This is calculation difference between manufacturer and our PC; please Google 'Memory card capacity' to get more information.The pursuit of the perfect person is not recommended to buy.

(1) Speeds vary by capacity.
[256GB-512GB]: Up to 150MB/s read speed engineered with proprietary technology to reach speeds beyond UHS-I 104MB/s, requires compatible devices capable of reaching such speeds. Write speed lower. Based on internal testing; performance may be lower depending on host device, interface, usage conditions and other factors. 1MB=1,000,000 bytes.
[64GB-128GB]: Up to 140MB/s read speed engineered with proprietary technology to reach speeds beyond UHS-I 104MB/s, requires compatible devices capable of reaching such speeds. Write speed lower. Based on internal testing; performance may be lower depending on host device, interface, usage conditions and other factors. 1MB=1,000,000 bytes.
[32GB]: Up to 120MB/s read speed engineered with proprietary technology to reach speeds beyond UHS-I 104MB/s, requires compatible devices capable of reaching such speeds. Write speed lower. Based on internal testing; performance may be lower depending on host device, interface, usage conditions and other factors. 1MB=1,000,000 bytes.
[16GB]: Up to 80MB/s read speed; write speed lower. Based on internal testing; performance may be lower depending on host device, usage conditions, and other factors. 1MB=1,000,000 bytes.
(2) 1GB=1,000,000,000 bytes. Actual user storage less.
(3) Full HD (1920x1080) and 4K UHD (3840x2160) video support may vary based upon host device, file attributes, and other factors. Visit the SanDisk Video Knowledge Base for more information.
