What about for 4K multi-monitor support? No matter what type of computer you have, you probably have one or more of the high speed connection types covered in this article. The USB 2. You have likely used a USB 2. Even though USB 3. Many devices do not yet use USB 3.
Because USB 2. OK great, so how fast is USB 2. For quick reference, Mbps equals 1 Gbps, which is considered gigabit. The USB 3. USB 3. So, what does that amount to? In , USB 3. This means that USB 3. SATA, of course, is a connection type that is used to connect an internal hard drive to a computer.
So, inside your desktop or laptop is the hard drive, which in most cases, connects to the motherboard using a SATA interface. With eSATA, an external hard drive can use that same connection type and technology to be connect to the computer. The hard drive inside a computer is quicker than a standard external hard drive USB 2. Thunderbolt cables are the newest connection type featured on this list.
Thunderbolt is capable of more than other connection types, but we will get to that later. That's impressive, but not as much as the newer USB 3. Right click on the device and select Properties. In the Properties window, select the 2nd tab called Policies and you will see two options. Most likely if you are experiencing slow speeds, it is set to the default Quick removal. Click Start Test and it will sequentially read and write a MB file to get the scores.
For information on connecting Firewire devices to Thunderbolt 3 Type C ports, please see this article. Thunderbolt 3 is really fast, transmitting at a whopping max transfer rate of 40Gbps. That makes it four times faster than USB 3. The main difference between the two is that FireWire is made to handle more data than USB , particularly audio and visual information.
For example, a 2. Firewire is rated at 3 Gbps and 6 Gbps Firewire is most often used to connect digital camcorders, external hard drives, and other devices that can benefit from the high transfer rates up to Mbps supported by the Firewire connection. The iSight camera used for chatting on the Mac connects using a Firewire cable. The release of USB 3. USB 3. Using the same hard drive, but connected to our Mac Pro, we found the FireWire connection to be 19 percent faster than the USB on the copy to the external drive, 21 percent faster on both the duplication test and the copy files test, and exactly the same in terms of performance difference on the AJA read and write tests as with the MacBook Pro.
The My Book tested on the Mac Pro showed the FireWire connection to be 48 percent faster than USB at copying the file to the external drive, 54 percent faster duplicating the file, and 49 percent faster copying over our files and folders.
The AJA write tests showed the connection writing twice as many megabytes per second as the USB connection, and 49 percent faster reading.
We also tested a zippy little Verbatim portable drive, which was 23 percent faster than USB in the copy to external test on the MacBook Pro, 21 percent faster at the duplication test, 14 percent faster on the file copy test, 42 percent faster on the AJA write throughput, and 8 percent faster on the AJA read throughput.
Connected via FireWire , we saw FireWire speeds 42 percent faster than USB at our copy to external test, 55 percent faster on our duplication test, 32 percent faster in the files test, and two times faster in the AJA read and write scores. Connected to the FireWire port, the Verbatim was 47 percent faster at our copy to test than when connected over USB. Copy and Duplicate scores are in minutes:seconds lower is better.
