Such configuration delivers high-speed storage that is ideal for video editing.

Categorized Notifications

TOS 5.1 optimizes system messages and divides message notifications into four levels: information, success, error, and warning. Each level of messages is marked with a more eye-catching symbol of different colors. User can always keep track of any abnormalities in the system and ensure the security of the system and data.

USB Storage Management
