Frequently Asked Questions

What is the difference between USB 3.0, 3.1, and 3.2?

USB 3.0 (now called USB 3.2 Gen 1) offers 5Gbps speed. USB 3.1 Gen 2 (now USB 3.2 Gen 2) offers 10Gbps. USB 3.2 Gen 2x2 offers 20Gbps. For flash drives, actual performance is often limited by NAND flash speed rather than interface. Most USB flash drives use USB 3.2 Gen 1 (5Gbps) which is sufficient for typical flash drive speeds up to 400MB/s.

USB 3.2 Gen 1 (5Gbps) is sufficient for most flash drives.

What speed class should I choose for microSD cards?

For general use (smartphones, tablets), Class 10 or UHS-I U1 is sufficient. For 4K video recording, choose UHS-I U3 or UHS-II U3 (minimum 30MB/s write). For action cameras and drones, V30 or higher is recommended. For professional video, consider V60 or V90 cards. Higher speed classes provide better performance but at higher cost.

Choose V30 or higher for 4K video, U3 for Full HD video, U1 for general use.

What is the difference between portable SSD and USB flash drive?

Portable SSDs use SSD technology with higher performance (up to 1000MB/s+), higher capacities (up to 2TB+), and better endurance. USB flash drives use simpler controller technology with lower performance (up to 400MB/s), smaller capacities (up to 1TB), and lower cost. Portable SSDs are ideal for professional use, large file transfers, and running applications. Flash drives are suitable for everyday file storage and transfer.

Choose portable SSD for performance and capacity, flash drive for portability and cost.

Do I need a special card for 4K video recording?

Yes, 4K video recording requires memory cards with sufficient write speed. Look for UHS Speed Class 3 (U3) or Video Speed Class 30 (V30) minimum, which guarantee 30MB/s sustained write speed. For high bitrate 4K or 8K video, consider V60 or V90 cards. Using insufficient cards can result in recording errors, dropped frames, or corruption. Always check your camera's recommended card specifications.

Use V30 or higher rated cards for reliable 4K video recording.

Are portable SSDs durable for travel?

Longsys portable SSDs are designed for mobility with shock and vibration resistance. Unlike HDDs, SSDs have no moving parts, making them inherently more durable for travel. However, they should still be protected from extreme temperatures, moisture, and physical impact. Many portable SSDs include rubber bumpers or metal enclosures for additional protection. Always safely eject before disconnecting to prevent data corruption.

Portable SSDs are excellent for travel - more durable than HDDs with no moving parts.
