4. Maintenance
- Handle with Care: Avoid dropping the flash drive or exposing it to excessive force, as this may cause physical damage.

- Type-C Adapter: The Type-C adapter is shipped randomly in black or silver. This does not affect functionality.
5. Troubleshooting
- Displayed Capacity Discrepancy: The displayed storage capacity may differ slightly from the advertised 256GB/512GB. This is due to different calculation methods used by storage manufacturers (1GB=1000MB) and computers (1GB=1024MB). This is normal and does not indicate a defect.
- Transfer Speed Variation: Actual read and write speeds may vary based on the connected device, processor performance, and file types being transferred.
- iOS App Requirement: For iPhone and iPad users, ensure the "ROSPE" app is downloaded and installed from the App Store for proper functionality.
