    Don't buy it. It's a scam. Data Transfer is terrible. Slow Speed. Got a replacement from Sandisk. The replacement has the same issues as well.

      Hi Sidhu, Please be aware that slow data transfer speeds may be caused by various factors, such as the type of file being transferred, the speed of the USB port, compatibility issues with the devices being used, and host device configuration. To troubleshoot this problem, try using different USB ports, update your drivers, and use the drive by connecting it to a compatible USB port. If the issue persists, it is recommended that you contact Sandisk Support again for assistance as we are unable to locate the case details using the information you shared. SanDiskConnections
