4. Operating Instructions

Data Transfer:

Once connected, the SSD functions like any other external storage device. You can drag and drop files, copy and paste, or use your device's file management system to transfer data.

• High Speed: The USB 3.2 interface allows for read speeds up to 450 MB/s and write speeds up to 400 MB/s, enabling quick transfer of large files, photos, and videos.
• Capacity Note: The advertised capacity (e.g., 128GB) is calculated using the decimal system (1GB = 1,000MB). Operating systems use binary measurement (1GB ≈ 1,024MB), resulting in a slightly lower formatted capacity (e.g., 128GB ≈ 119GB). This is standard for all storage devices.

5. Maintenance

Formatting:

The default format of this USB drive is EXFAT, which offers broad compatibility across various operating systems. If your device does not recognize the drive or requires a different file system, formatting may be necessary.

Caution: Formatting the drive will erase all data. Back up any important files before proceeding.

General Care:

• Avoid exposing the SSD to extreme temperatures, direct sunlight, or high humidity.
• Do not drop or subject the SSD to strong impacts.
• Always safely eject the drive from your computer or device before unplugging it to prevent data corruption.
• Keep the USB-C connector clean and free from dust or debris.

6. Troubleshooting

Device Not Recognized:

• Check Connection: Ensure the SSD is fully and correctly inserted into the USB-C port.
• Compatibility: Verify that your device supports USB OTG (On-The-Go) functionality for external storage. Refer to your device's manual.
• Try Another Port/Device: Test the SSD with a different USB-C port or another compatible device to rule out a port issue.
• Reformat (Last Resort): If the drive is new and not recognized, or if it was previously used with a different system, it might require formatting to a compatible file system (e.g., EXFAT). Refer to the "Maintenance" section.

Slow Transfer Speeds:

• USB Version: Ensure your device's USB-C port supports USB 3.2 for optimal speeds. Connecting to a USB 2.0 port will result in significantly slower transfer rates.
• File Size/Type: Transferring many small files can be slower than transferring a few large files.
• Device Performance: The speed of your host device (computer, phone) can affect transfer rates.

Drive Feels Warm During Use:

• It is normal for solid-state drives to generate some heat during active use, especially during large data transfers or continuous recording (like 4K ProRes). If the drive becomes excessively hot or causes performance issues, discontinue use and contact support.
