Setup Instructions
Package Contents:
- SSK Portable SSD
- USB-C to USB-A Cable
- USB-C to USB-C Cable
Connecting the SSD:
- Select the appropriate cable: Use the included USB-C to USB-C cable for devices with a USB-C port, or the USB-C to USB-A cable for devices with a standard USB-A port.
- Connect to your device: Plug the USB-C end of the cable into the SSK Portable SSD. Plug the other end of the cable (USB-C or USB-A) into the corresponding port on your computer, smartphone, tablet, or gaming console.
- Power Indicator: The SSD features an LED indicator that illuminates to show instant activity and proper connection.
- Plug and Play: The SSK Portable SSD is designed for plug-and-play functionality. Once connected, most operating systems will automatically recognize the drive, making it ready for use without additional driver installation.
For optimal performance, ensure your device's USB interface supports USB 3.2 Gen 2 (10Gbps) standards.

Operating Instructions
Data Transfer:
Once connected, the SSD will appear as an external drive on your device. You can drag and drop files, copy and paste, or use your device's file management system to transfer data to and from the SSD.
Performance:
- Speed: The SSD offers blazing-fast read speeds of up to 1050MB/s and write speeds of up to 1000MB/s.
- USB 3.2 Gen 2: To achieve these speeds, ensure both your computer's USB interface and the data cable used are USB 3.2 Gen 2 (10Gbps) standard.
- SLC Caching: Approximately 1/4 of the available capacity is allocated for high-speed caching. Writing speeds remain stable when the file size of each transfer is less than 1/4 of the remaining usable capacity. For example, if 600GB is available, transfers less than 150GB will maintain high speed.
Compatibility:
The SSK Portable SSD is compatible with a wide range of operating systems and devices, including:
- Windows
- Mac OS
- Android smartphones and tablets (OTG-enabled Type-C)
- USB-C iPads
- Linux
- Gaming consoles (PS5, Xbox, PS4)
- Smart TVs and Smart Speakers
iPhone 4K ProRes Video Capture:
This portable SSD supports 4K60Hz ProRes HDR video capture for iPhone, providing ample storage for high-quality video recording directly to the drive.


Maintenance
Physical Care:
- Durability: The SSD features an aluminum alloy shell, providing solid and shockproof protection. It is designed to withstand drops from up to 2 meters without damage.
- Handling: Avoid exposing the SSD to extreme temperatures, direct sunlight, or moisture.
- Cleaning: Use a soft, dry cloth to clean the exterior of the SSD. Do not use liquid cleaners or solvents.
Heat Management:
The aluminum alloy case and special heat dissipation design ensure superior heat management. The case temperature typically peaks around 105.58°F (40.88°C), ensuring reliable performance without overheating during operation.
Data Integrity:
- S.M.A.R.T. Monitoring: The SSD supports S.M.A.R.T. (Self-Monitoring, Analysis, and Reporting Technology) to monitor its health and predict potential failures.
- TRIM Technology: TRIM technology helps maintain consistent write speeds and extends the overall lifespan of the SSD by efficiently managing data blocks.

Troubleshooting
SSD Not Recognized:
- Check Connection: Ensure the USB cable is securely plugged into both the SSD and your device.
- Try Different Port/Cable: Test with a different USB port on your device or a different compatible USB cable to rule out port or cable issues.
- Restart Device: Sometimes, a simple restart of your computer or smartphone can resolve recognition issues.
- Check Device Manager (Windows) / Disk Utility (Mac): Verify if the drive appears in your system's disk management tools. It might need to be initialized or formatted if it's a new drive or if the file system is incompatible.
Slow Transfer Speeds:
- USB Port Standard: Ensure your device's USB port and the cable used are USB 3.2 Gen 2 (10Gbps) compatible. Older USB standards (e.g., USB 2.0, USB 3.0/3.1 Gen 1) will result in lower speeds.
- File Size and Caching: For very large single file transfers exceeding 1/4 of the remaining available capacity, speeds might stabilize at a lower rate after the SLC cache is filled. This is normal behavior for SSDs utilizing SLC caching.
- Background Processes: Close any unnecessary applications or background processes that might be consuming system resources or disk I/O.
Capacity Display Discrepancy:
It is common for the displayed capacity of an SSD to appear slightly lower than the advertised capacity on operating systems like Windows. For example, a 1TB SSD may show around 931GB. This is due to differences in how storage capacity is calculated:
- Manufacturers: Typically define 1GB as 1,000,000,000 bytes (decimal).
- Operating Systems (e.g., Windows): Typically define 1GB as 1,073,741,824 bytes (binary, or 1024 MB).
This difference in calculation results in a 7% to 10% reduction in displayed capacity, which is normal and not indicative of a faulty drive.
