4. Setup
4.1 Magnetic Attachment
The Yottamaster PSSD features a strong magnetic design for secure attachment to compatible devices, particularly smartphones. If your phone does not have a built-in magnet or you are using a normal phone case, you can use the included magnetizing ring for better attachment.
- For phones with built-in magnets or magnetic cases: Simply align the PSSD with the magnetic area on your phone or case until it snaps securely into place.
- For phones without built-in magnets or with normal cases: Attach the provided magnetizing ring to the back of your phone or phone case. Ensure it is centered for optimal magnetic force. Then, attach the PSSD to the magnetizing ring.
4.2 Connecting to Devices
The Yottamaster PSSD is a plug-and-play device compatible with various Type-C interface devices and operating systems. Use the provided USB-C to USB-C data cable to connect the PSSD to your device.
5. Operating Instructions
5.1 General Use
Once connected, the PSSD will typically appear as an external drive on your device. You can then drag and drop files, or use it as a target for saving documents, photos, and videos.
5.2 Maximizing Transfer Speed (20Gbps)
To achieve the maximum transfer speed of 20Gbps (2000MB/s), the following conditions must be met:
- Device Interface: The host device (e.g., computer, phone) must support a USB 3.2 Gen 2x2 interface. While the PSSD is backward compatible with older USB standards, the transfer rate will be limited by the maximum speed the connected interface can handle.
- Data Cable: The data cable used must support a transfer rate of 20Gbps. Always use the provided cable or a certified equivalent.
- Connected Device Speed: The connected device itself must be capable of reaching read/write speeds of 2000MB/s.
Note on Phone Compatibility: When using the PSSD with a phone, these conditions also apply. For example, with an iPhone 16 Pro/Max, the maximum speed can reach 10Gbps. However, older models like the iPhone 16/16 Plus may only reach USB 2.0 transfer speeds of 480Mbps due to hardware limitations.
5.3 4K ProRes Video Recording
The Yottamaster PSSD is designed to support professional storage technology, enabling 4K/60Hz video recording for compatible devices like the iPhone 16 Pro/Max without interruptions or frame drops. This allows for instant editing and saving of high-quality video content directly to the PSSD.
6. Maintenance
To ensure the longevity and optimal performance of your Yottamaster PSSD, follow these maintenance guidelines:
- Safe Ejection: Always safely eject the PSSD from your device before disconnecting it to prevent data corruption.
- Cleaning: Use a soft, dry cloth to clean the exterior of the PSSD. Avoid using liquid cleaners or abrasive materials. Keep the magnetic ring clean for optimal attachment.
- Storage: Store the PSSD in a cool, dry place away from extreme temperatures and direct sunlight.
- Heat Dissipation: The PSSD is designed for efficient heat dissipation to maintain low-temperature operation. Ensure it is not covered or placed in an enclosed space during heavy use to allow for proper airflow.
- Physical Protection: While the PSSD offers dust and drop resistance, avoid unnecessary impacts or exposure to harsh conditions to protect your data.
7. Troubleshooting
7.1 PSSD Not Detected
- Ensure the USB-C cable is securely connected to both the PSSD and your device.
- Try connecting the PSSD to a different USB-C port on your device.
- Test with a different USB-C to USB-C cable to rule out cable issues.
- Restart your computer or device and try connecting again.
- Check your device's disk management or storage settings to see if the drive is recognized but not assigned a drive letter or needs formatting.
7.2 Slow Transfer Speeds
- Verify that your host device's USB-C port supports USB 3.2 Gen 2x2 (20Gbps) for maximum speed. Older USB standards will result in lower speeds.
- Ensure you are using the provided 20Gbps compatible USB-C cable.
- Confirm that your device's internal storage or the application you are using can handle 2000MB/s read/write speeds.
- Close any unnecessary background applications that might be consuming system resources or bandwidth.
- For phone connections, remember that phone hardware limitations (e.g., iPhone 16/16 Plus USB 2.0) will cap transfer speeds regardless of the PSSD's capability.
7.3 Magnetic Attachment Issues
- Ensure the magnetic ring (if used) is properly adhered and centered on your phone or case.
- Clean the surfaces of both the PSSD and your phone/magnetic ring to ensure no debris is interfering with the magnetic connection.
- If using a thick phone case, the magnetic force might be weakened. Consider using a thinner case or attaching the magnetic ring directly to the phone.
8. User Tips
- Data Backup: While the PSSD is durable, regularly back up critical data to multiple locations to prevent unforeseen data loss.
- Optimal Performance: For the best performance, always use the PSSD with devices and cables that support USB 3.2 Gen 2x2 (20Gbps).
- Firmware Updates: Check the Yottamaster official website periodically for any firmware updates for your PSSD, which may improve performance or compatibility.
- File System: If you encounter compatibility issues with certain devices, you may need to format the PSSD to a different file system (e.g., exFAT for broad compatibility across Windows and Mac, or APFS/NTFS for specific OS optimization). Always back up data before formatting.
