1. Introduction
The SSK External Portable SSD is a high-speed solid-state drive designed for efficient data transfer and storage across various devices. Featuring a robust aluminum enclosure and USB 3.2 Gen2 connectivity, it offers fast performance and broad compatibility for users on the go.

2. Setup
2.1 Package Contents
- SSK External Portable SSD
- USB-C to USB-C Cable
- USB-A Adapter
2.2 Connecting the SSD
- Connect one end of the provided USB-C cable to the SSK Portable SSD.
- Connect the other end of the USB-C cable to your host device (e.g., laptop, smartphone, tablet).
- If your host device only has a USB-A port, attach the USB-A adapter to the USB-C cable before connecting it to your device.
- The LED indicator on the SSD will illuminate to show it is powered on and active.

2.3 Initial Use and Formatting
Upon first connection, your operating system may prompt you to format the drive. For optimal performance and compatibility across different systems (Windows, macOS, Linux, Android), it is recommended to format the drive to a suitable file system (e.g., exFAT for broad compatibility, NTFS for Windows, APFS for macOS). Please back up any existing data before formatting.

3. Operating Instructions
3.1 Data Transfer
The SSK Portable SSD utilizes USB 3.2 Gen2 technology, providing blazing fast transfer speeds. You can expect read speeds of up to 550MB/s and write speeds of up to 500MB/s. Actual speeds may vary depending on your host device, operating system, and the specific application used.

3.2 Stable High Speed Performance
To ensure consistent performance during large file transfers, the SSD allocates approximately 25% of its available capacity for high-speed SLC caching. This mechanism helps maintain stable 6Gbps speeds, preventing slowdowns even with extensive data operations.

3.3 OTG Functionality
The SSK Portable SSD supports On-The-Go (OTG) functionality, allowing direct connection and data transfer with compatible smartphones and tablets. Its ultra-low power consumption (less than 5 Watts) ensures seamless usability on mobile devices without significant battery drain.

3.4 Auto Sleep
The SSD features an automatic sleep mode that activates after 20 minutes of inactivity to conserve power and extend the drive's lifespan.
4. Maintenance
4.1 Drive Health Monitoring
The SSK Portable SSD incorporates S.M.A.R.T. (Self-Monitoring, Analysis, and Reporting Technology) to monitor the drive's health and predict potential failures. Regularly check your drive's S.M.A.R.T. status using appropriate software on your computer to ensure data safety.
4.2 TRIM Technology
TRIM technology is supported to optimize the SSD's performance and longevity. It helps the operating system communicate with the SSD to efficiently manage data blocks, ensuring consistent write speeds over time.

4.3 Heat Dissipation
The SSD features a thick aluminum alloy case designed for superior heat dissipation. This robust structure helps maintain optimal operating temperatures, ensuring reliable performance and preventing overheating during intensive use.

5. Troubleshooting
5.1 Capacity Display Discrepancy
The displayed capacity of your SSD may vary slightly between operating systems. For example, a 128GB SSD might show around 116GB on Windows, while macOS typically displays the full 128GB. This difference is due to varying algorithms in how 1GB is calculated (1024MB on Windows vs. 1000MB on SSDs).
5.2 Slow Transfer Speeds
If you experience slower than expected transfer speeds, consider the following:
- Host Device: Ensure your device supports USB 3.2 Gen2 for maximum speeds. Older USB ports (e.g., USB 2.0, USB 3.0/3.1 Gen1) will limit performance.
- Cable/Adapter: Use the provided USB-C cable and USB-A adapter, as third-party accessories may not support the full speed.
- Operating System & Application: The performance can be influenced by the operating system and the specific application used for data transfer.
- File Size: While SLC caching helps, extremely large single files or a multitude of small files can sometimes affect sustained write speeds after the cache is filled.
5.3 Drive Not Detected
If the SSD is not detected by your device:
- Ensure the cable is securely connected to both the SSD and the host device.
- Try a different USB port on your device.
- If using the USB-A adapter, ensure it is properly attached.
- Restart your computer or device.
- Check your device's Disk Management (Windows) or Disk Utility (macOS) to see if the drive is recognized but unformatted or uninitialized.
