ASMT 2115 USB device drivers are necessary for drives that use the SATA port at the drive end and the USB port at the system end. Samsung is one of the leading producers of transistor-based Solid State Drives (SSD). SSDs are much faster than HDDs and store data differently than HDDs. They require their driver software to work according to the SSD’s data storage format. On Windows, users need not worry about these drivers as most of these are preinstalled or are installed on the fly when the device is plugged in.

If you are on an older version of Windows, such as Windows 7, and have a slightly different kind of SSD, such as one with an ASMT 2115 USB interface, you might need to install some additional device driver. You could go to the manufacturer’s website (Samsung in this case) and download the driver and then install it manually.
