Connectivity

• Interface: USB 3.1 Gen 1
• USB Speed: Up to 5Gbps theoretical bandwidth
• Drive Connector: Micro-USB
• Host Connector: USB Type-A

The 5Gbps figure represents the USB interface limit, not the actual mechanical HDD read/write speed.

Three-Stage Shock Protection

One of the key features of the StoreJet 25M3S is its three-stage shock protection system.

The rugged construction is designed to provide additional protection against accidental impacts and drops during everyday use and transportation. Transcend states that the product is tested using procedures based on the MIL-STD-810G 516.6 military drop-test standard.

This makes it particularly useful for:

• Students
• Professionals
• Travelers
• Photographers
• Content creators
• Users carrying important backups

Shock resistance reduces risk but does not make the HDD immune to physical damage.

One-Touch Auto Backup

The StoreJet 25M3S features a dedicated One-Touch Auto-Backup button.

With Transcend Elite software, users can configure the button to quickly back up or synchronize important files.

This can simplify backups of:

• Documents
• Photos
• Videos
• Work folders
• Personal files
• Project data

Transcend Elite Software

The drive supports Transcend Elite, Transcend's data-management software for compatible Windows and macOS systems.

Functions include:

• Backup
• Restore
• File management
• Synchronization
• Data encryption
• One-Touch Auto Backup

Transcend notes that Elite software is required to use the drive's One-Touch Auto-Backup and AES encryption functions.

AES Encryption Support

With compatible Transcend Elite software, users can protect important data using AES encryption functionality.

This is useful for:

• Business documents
• Personal files
• Work projects
• Private photos
• Important backups
• Sensitive documents

RecoveRx Data Recovery Software

The StoreJet 25M3S also supports Transcend RecoveRx, a data-recovery utility designed to search supported storage devices for recoverable deleted files.

It can help search for file types such as:

• Photos
• Documents
• Music
• Videos

Successful file recovery is not guaranteed and depends on whether the deleted data has been overwritten.

This means:

• No external AC adapter
• No separate power supply
• Easy laptop use
