Introduction

The Ultra Dual Drive Go USB Type-C Flash Drive (SDDDC3-512G-G46) promises high-speed data transfer and robust build quality. I’ve been using this 512GB drive for the past few weeks, putting it through its paces with various file types and transfer scenarios. This review will detail my experiences, highlighting both its strengths and weaknesses.

Key Features

The Ultra Dual Drive Go boasts a dual-connector design (USB-C and USB-A), making it compatible with a wide range of devices. The compact and durable design, along with the included keyring attachment, makes it ideal for portability. The stated USB 3.1 Gen 1 speeds promise quick file transfers, and the robust internal configuration is designed to protect the drive from everyday bumps and drops.

Performance

In my testing, the transfer speeds were generally impressive. Copying large files (several GBs of video footage) to my MacBook Pro via USB-C resulted in average read speeds very close to the advertised 150 MB/s. Transferring files to my older Windows PC via the USB-A connector was slightly slower, but still notably faster than with older USB 2.0 drives. I did encounter occasional minor slowdowns when transferring numerous smaller files simultaneously. This was likely due to the drive’s controller handling multiple file requests, rather than any major performance issue.

The durability claims also seem to hold up. I’ve accidentally dropped the drive a few times, and it has survived without any apparent damage. The protective cap for the USB-C connector is particularly handy, adding a layer of protection to the delicate connector.

Pros & Cons

Pros:

• Dual connector (USB-C & USB-A) for broad compatibility.
• Fast read speeds.
• Compact and durable design.
• Included keyring attachment.

Cons:

• Slight performance dip when transferring many small files simultaneously.
• The cap could potentially be easily lost.

Final Verdict

The Ultra Dual Drive Go USB Type-C Flash Drive (SDDDC3-512G-G46) is a solid and reliable portable storage solution. The speed, convenience, and durability make it a great option for transferring files between various devices. While minor performance issues exist, they are unlikely to affect most users. I would recommend this drive to anyone needing a portable and relatively fast storage option, especially those with both USB-C and USB-A devices.
