Quick answer: our top pick is UGREEN USB-C 10 Gbps, 240 W, 1 m (USB 3.2 Gen 2 · 10 Gbps · 240 W).
Choosing the right USB-C cable for an SSD determines the speed and stability of data transfer. Not every USB-C cable supports the same standards, which is why it is worth paying attention to technical specifications that affect performance. A portable drive operates at the speed of the slowest component: the computer port, the cable, and the drive itself.
Why is a good USB-C cable important?
Data transfer speed
The supported USB standard determines the maximum file transfer speed:
- USB 3.2 Gen 2 - up to 10 Gbps (approx. 1050 MB/s)
- USB 3.2 Gen 2x2 - up to 20 Gbps (approx. 2000 MB/s)
- USB4 - up to 40 Gbps (up to approx. 4000 MB/s)
Fun fact: The Gen 2x2 designation means that the USB-C cable uses two 10 Gb/s lanes simultaneously.
Charging power
A drive does not need 240 W charging: cable power does not affect data speed. However, it is worth watching out for typical charging cables: a USB-C charging cable running on the USB 2.0 standard (including 60 W and 100 W) will throttle any drive to 480 Mb/s.
Compatibility
A good cable should work with a variety of devices:
- Computers and laptops,
- Smartphones and tablets,
- Gaming consoles,
- Digital cameras,
- External SSDs.
Durability
Solid build quality ensures a longer lifespan for the cable:
- Nylon braid - protection against abrasion,
- Aluminum plug housings - enhanced mechanical durability,
- Reinforced connectors - resistance to frequent bending.
USB-C cable for an SSD - what to look for when choosing?
USB standard and transfer speed
A portable drive operates at the speed of the slowest component: the computer port, the cable, and the storage media itself. For example, the Samsung T7 (USB 3.2 Gen 2, 10 Gb/s) reads up to 1050 MB/s and writes up to 1000 MB/s; a 10 Gb/s USB-C cable is completely sufficient for it. On the other hand, USB 3.2 Gen 2x2 (20 Gb/s) drives and enclosures require a Gen 2x2 port on the computer, which many laptops lack - in that case, they operate at 10 Gb/s. USB4 and Thunderbolt NVMe enclosures (40 Gb/s) require a USB4 or Thunderbolt cable and a corresponding USB4 or Thunderbolt port on the computer.
- USB 3.1 Gen 1 (USB 3.0) - up to 5 Gbps.
- USB 3.2 Gen 2 - up to 10 Gbps.
- USB 3.2 Gen 2x2 - up to 20 Gbps.
- USB4 - up to 40 Gbps.
Fun fact: Thunderbolt 4 and USB4 transmit 40 Gb/s, which is four times faster than USB 3.2 Gen 2.
Power Delivery (PD) support
If a single cable is to be used simultaneously to power the computer, it is worth choosing a model supporting 100 W or 240 W. However, charging power alone will not speed up the external drive's performance.
Material and construction
- Nylon braid - protects against abrasion.
- Aluminum connectors - reinforce the plug structure.
- Flexible strain relief - protects the cable from fraying near the plug.
Cable length
- Short cables (0.5 m - 1 m) - optimal for high transfer rates and convenience when working with a laptop.
- Longer cables (1.5 m - 2 m) - more convenient for desktop computers, although at the highest speeds they require cables with superior build quality.

Summary
The choice of a USB-C cable for an SSD should depend on the specifications of the drive itself and the ports on your computer. For popular USB 3.2 Gen 2 drives, a 10 Gb/s cable is sufficient, while for Gen 2x2 models or USB4 NVMe enclosures, it is worth choosing a cable with a throughput of 20 Gb/s or 40 Gb/s.
