Frequently asked questions

What is the Rocstor CommanderX EC31?

The CommanderX EC31 is a 4TB encrypted desktop external hard drive designed for secure data storage. It features hardware AES-256 encryption, FIPS 140-2 validation, and secure token key authentication (3XTOKEN) to protect sensitive data while delivering fast USB 3.1/USB 3.0 transfer speeds on Windows and Mac systems.

How secure is the encryption on this drive?

Security is hardware-based with AES-256-bit encryption and FIPS 140-2 validation, meaning encryption is performed by dedicated hardware on the drive. Access is controlled through the 3XTOKEN secure key, and data remains protected even if the device is removed from a computer.

What capacity and performance can I expect?

The EC31 offers 4TB of storage with a 3.5" desktop form factor and a 7200 RPM drive. It supports USB 3.1 (Gen 2) and USB 3.0 interfaces for high-speed data transfers, making it suitable for backups, media libraries, and large data transfers.

Is this drive compatible with both Mac and PC?

Yes. The CommanderX EC31 is designed for cross‑platform use, providing seamless compatibility with macOS and Windows systems. Plug-and-play operation is supported, with encryption managed via the hardware token.

How do I use the 3XTOKEN key?

The 3XTOKEN is a hardware security key used to authenticate and unlock the encrypted drive. You insert or attach the token as directed by the on-device prompts or accompanying software, then follow the prompts to unlock and access the encrypted volume. This provides a strong form of two-factor protection when combined with the drive’s hardware encryption.

What file systems should I use when formatting the drive?

For cross‑platform compatibility, exFAT is commonly used because it works with both macOS and Windows without repartitioning. If you’re using the drive primarily on one platform, you can format it to the native file system (NTFS for Windows, HFS+ or APFS for macOS) depending on your workflow and software needs. Always back up any existing data before formatting.

Can I use this drive for ongoing backups?

Yes. The CommanderX EC31 is designed with reliable storage performance in mind and supports regular backup workflows. The hardware encryption ensures that backups are protected by design, and the 3XTOKEN authentication adds an additional layer of security for sensitive backups.

Is the drive plug-and-play, or do I need drivers?

In most cases, the CommanderX EC31 operates as a plug-and-play device on modern Windows and macOS systems. Depending on your OS version or security settings, you may be prompted to install drivers or management software provided by Rocstor to interact with the hardware token and encryption features.
