For weeks now, I’ve been putting the USB 3.0 to SATA Adapter Converter Cable Black (Model Number: C661) through its paces. This unassuming little adapter promises simplicity and speed, and I was curious to see if it delivered on those promises. My testing involved various 2.5-inch SATA hard drives and SSDs, ranging in size and age, to get a well-rounded perspective of its capabilities.

The C661’s key selling points are its simplicity and speed. The plug-and-play nature is a significant advantage, requiring minimal setup. The blue LED indicator provides clear visual feedback, confirming connection and power. The inclusion of support for both 7-pin and 15-pin SATA connections ensures compatibility with a wide range of drives. The USB 3.0 interface is the headline feature, promising rapid data transfer speeds.

My testing revealed mixed results. While the plug-and-play functionality worked flawlessly, the speed wasn’t always as impressive as advertised. With newer, faster SSDs, I experienced transfer rates that approached the theoretical limits of USB 3.0, a positive outcome. However, with older, slower hard drives, the bottleneck appeared to be the drive itself rather than the adapter. The adapter handled larger files (over 10GB) without any noticeable issues, maintaining a consistent transfer rate throughout the process. Overall, performance was acceptable, though not groundbreaking.

I also conducted a test to assess its stability. I ran a continuous transfer of a large video file (approximately 50GB) for several hours, and the adapter showed no signs of overheating or performance degradation. This suggests that the adapter is built to handle prolonged use.

Pros:

• Simple plug-and-play design.
• Clear blue LED indicator.
• Supports both 7-pin and 15-pin SATA connections.
• USB 3.0 interface for fast data transfer (with compatible drives).
• Stable performance during prolonged use.

Cons:

• Transfer speeds may not reach advertised rates with older hard drives.
• No external power supply – may not support high-power drives.

The C661 USB 3.0 to SATA adapter is a decent, affordable option for those needing a straightforward solution to connect 2.5-inch SATA drives to a computer. While it doesn’t always deliver the blazing-fast speeds implied by the USB 3.0 label, it’s reliable, easy to use, and perfectly adequate for many users. I would recommend it for users who primarily work with modern SSDs or have less demanding data transfer needs. For users working with older, slower hard drives or needing consistently high speeds for large files, I would suggest exploring options with external power supplies for enhanced performance.
