Features

Tool-Free Installation Function

The tool-free installation simplifies the process of installing or replacing an SSD, saving time and effort. This is very convenient for users who frequently swap or upgrade their SSDs, making the process quick and easy.

External Heat Dissipation Function

The external heat dissipation design, utilizing the aluminum enclosure, effectively cools the SSD, preventing performance degradation due to thermal throttling and ensuring stable, sustained performance during demanding tasks. This helps maintain consistent speeds.

Write Protection Function

This enclosure does not have a write protection function, so it is impossible to prevent data from being written to the SSD. Users needing this feature should consider alternative enclosures with write protection capabilities for data security.

UASP Support Function

Supporting UASP significantly increases data transfer speeds when connected to a UASP-compatible USB port, speeding up large file transfers and backups. This results in faster and more efficient data handling for compatible systems.

LED Indicator Function

The LED indicator provides a quick visual confirmation of the enclosure's operating status, making it easy to troubleshoot connection issues or confirm data transfer activity. This allows for easy monitoring of the enclosure's functionality.

Multiple Size Support Function

Supporting multiple M.2 SSD sizes (2230, 2242, 2260, 2280) provides flexibility when upgrading or repurposing existing SSDs, making it a versatile choice for various storage needs and drive sizes. This enhances its usability.
