Speeds Of SATA 3 Vs. Different USB 3 Versions

SATA 3 is an internal connection standard created to connect storage devices like SSDs and hard drives to your motherboard. It’s mainly used for internal connections, though you can get external SATA connectors (called eSATA). On the other hand, USB is an external connector standard, and internal connections tend to be faster than external connections.

If we compare the speeds of SATA 3 and USB 3, we can see that this is the case between these two as well. SATA 3 has a maximum speed of 6 Gigabits per second (Gbps), and standard USB 3 (also known as USB 3.0) can reach speeds up to 4.8Gbps.

However, two more recent versions of USB 3 are faster than SATA 3:

USB 3.1, with maximum speeds of 10Gbps
USB 3.2, which can reach top speeds of 20Gbps

Is SATA faster than USB 3.0?

So, if the USB 3 version you’re using is either 3.1 or 3.2, they are potentially faster than SATA 3 and eSATA. However, there are exceptions because USB speed isn’t fixed, and various things can affect the actual performance.

What Affects USB Speeds?

USB speed is determined by the controller chip, not the cable. For example, if you have a computer that has a USB 3.2 rating, it means the controller chip can run at 20Gbps. However, having a cable that doesn’t support the right speed will adversely affect the connection’s speed.

USB is a backward-compatible standard. This means you can connect USB 3 devices to USB 2 ports or a USB 1 device to a USB 3 port, and they are all compatible if you have the correct connectors. You may have to sacrifice some speed and performance to achieve this backward compatibility.

If your computer has a USB 3.2 port, it can run at 20Gbps. But if you connect an external hard drive rated for USB 3.0 (4.8Gbps), that’s the maximum speed it will run at, so it will be slower than SATA 3. But if every component in the connection supports USB 3.1 or 3.2, it can run much faster than SATA 3.

How Fast is USB 3.0 to SATA Cable?

The speed of a USB 3.0 to SATA cable, used to connect SATA storage devices like hard drives or solid-state drives (SSDs) to a USB 3.0 port, is primarily determined by the USB 3.0 interface’s capabilities and the performance of the connected storage device.

USB 3.0 Interface: USB 3.0, also known as USB 3.1 Gen 1 or SuperSpeed USB, has a theoretical maximum transfer speed of 5 Gbps (Gigabits per second), which translates to about 625 MB/s (Megabytes per second). However, real-world speeds are often lower due to various factors like device overheads, cable quality, and computer hardware.
SATA Interface: The speed of the SATA device also plays a crucial role. For instance, SATA III, the latest version widely used, has a maximum transfer rate of 6 Gbps (about 750 MB/s). However, the actual performance of the storage device (like an HDD or SSD) connected to the SATA end of the cable can vary. SSDs, being faster, can often come close to the maximum transfer rates of SATA III and USB 3.0, whereas HDDs might not.

In practical terms, when using a USB 3.0 to SATA cable, your transfer speeds will typically be somewhere between the speeds of the two interfaces, often limited by the slower of the two. For most consumer-grade applications, such as data backup or file transfer, these speeds are more than adequate.
