- For devices with a USB-A port (e.g., older desktops, laptops), use the USB-A adapter integrated into the cable and connect it to your device's USB-A port.

Operating Instructions
Data Transfer:
Once connected and recognized by your device, the Lexar SL300 operates like any other external drive. You can drag and drop files, copy and paste, or use your system's backup software to transfer data.
- Copying Files: Select the files or folders you wish to transfer from your computer, then drag them to the Lexar SL300 drive icon, or right-click and choose "Copy" then "Paste" into the SSD's folder.
- Deleting Files: Select unwanted files on the SSD and move them to the Recycle Bin/Trash. Remember to empty the Recycle Bin/Trash to free up space.
- Performance: The Lexar SL300 supports USB 3.2 Gen 2, offering read speeds up to 1050MB/s and write speeds up to 1000MB/s. To achieve optimal speeds, ensure your host device also supports USB 3.2 Gen 2 or higher. Connecting to older USB 2.0 or 3.0 ports will result in lower transfer speeds.

- Cleaning: Use a soft, dry, lint-free cloth to clean the exterior of the SSD. Do not use liquid cleaners or solvents.
