Actual transfer speeds depend on SSD model, host device, cable quality, and system environment

High-speed operation may cause the enclosure surface to become warm due to heat dissipation

For SSDs with metal heat sinks, it is recommended to remove the heat sink before installation for better fit and cooling

USB-A data cable is not included; USB-A port requires separate cable

Product appearance and data cable design may vary between batches without affecting functionality

Back up important data before use; UGREEN is not responsible for data loss

SSD lifespan depends on usage and environment; recommended replacement every 3-5 years
