The SanDisk Ultra Dual Drive m3.0 (SDDD3-128G-G46) promises convenient file transfer between USB-A and USB-C devices. I’ve been using this 128GB drive for several weeks now, putting it through its paces to see if it lives up to the hype. This review will detail my experiences with the drive, covering its strengths and weaknesses.

The standout feature is, of course, the dual connector design. Having both USB-A and USB-C connectors is incredibly handy in today’s world of mixed devices. The compact size makes it easy to slip into a pocket or bag, and its multicoloured design helps it stand out. SanDisk also provides the Memory Zone app for easy file management, although I found its functionality fairly basic.

Transfer speeds were generally good, though not as fast as advertised. While I saw speeds nearing 150 MB/s for reads on my newer MacBook Pro, the write speeds were consistently slower, particularly with larger files. This is a common issue with many flash drives, but it’s worth noting. The drive has performed reliably without data loss, even after extensive testing that involved transferring large video and photo files across multiple devices. I even left it plugged into my laptop throughout various shutdowns, without causing any damage to the device or the drive.

The app was, as mentioned before, a bit underwhelming, offering only minimal organisation features. I preferred managing the files directly through my computer’s file explorer.

Pros:

• Convenient dual connector (USB-A and USB-C)
• Compact and portable design
• Generally reliable performance
• Good read speeds for larger files

Cons:

• Write speeds could be faster
• Basic file management app
• Advertised speed was not always achieved

Overall, the SanDisk Ultra Dual Drive m3.0 (SDDD3-128G-G46) is a solid choice for those needing a portable and versatile flash drive. The dual connector is a major plus, and the reliability is commendable. While the write speeds aren’t blazing fast and the app leaves something to be desired, the convenience and ease of use make it a worthwhile purchase. I would recommend it to anyone needing a simple and portable way to transfer files between devices, especially those using both USB-A and USB-C connectors.
