Which imacs have usb 3

If you use a DLSR or other type of stand-alone camera, it might have a way to transfer your files wirelessly. Trying to connect FireWire and devices gets iffy. But maybe you have an older printer, or you find wireless printing unreliable. Most consumer printers have a USB-B port. Then you plug the adapter into the laptop. MagSafe was a laptop lifesaver in instances where someone tripped over the power cable.

But you can still add a MagSafe connector. Use Audio-Out — or — with headphones, speakers, and other audio-output devices that connect using an audio cable that has a 3. On inch and inch MacBook Pro models with Apple silicon, you can connect high-impedance headphones to the 3. Use Audio-In with a microphone or other audio-input device that connects using an audio cable that has a 3.

Use these ports with devices that connect using a USB-A cable. Use these ports with displays and other devices that connect using a Thunderbolt cable.

Thunderbolt and Thunderbolt 2 are not the same as Mini DisplayPort. They have the same shape, but use different symbols on the cable and port. Use this port with displays that connect using a Mini DisplayPort cable. Mini DisplayPort is not the same as Thunderbolt or Thunderbolt 2. USB 3. Raw speed isn't the only improvement in USB 3. The new generation uses two unidirectional data paths: one to transmit and one to receive. So, you no longer need to wait for a clear bus before sending information.

It has the same transfer rate 5 Gbps theoretical max , but you can combine it with the USB Type-C connector to provide up to watts of additional power.

In other words, it refers to the shape of the port. It provides the same transfer speeds as a USB 3. It's also the port you plug your AC power adapter into to charge the device's battery. Some Apple device models combine USB 3. The USB-C port has some interesting hallmarks:. Just because a device has a USB-C connector doesn't automatically mean that the port supports video or Thunderbolt-like speeds.

Note that the menu options may differ depending on the operating system installed on your Mac. Select the Apple menu, and then select About This Mac. Select System Report. Select USB under the Hardware heading.

USB 3 also has a feature common in FireWire and Ethernet systems: a defined host-to-host communications capability. Through this capability, you can use USB 3 with multiple computers and peripheral devices at the same time. All USB 2. All Mac models after have USB 3.

In this a mistake on your part or am I missing something? DavidAnderson You are, of course, correct. I was deliberately ignoring the x1 and x2 distinction as the x2 is not supported by the iMac. I will make changes. Please check the changes. System Information also displays the following under Thunderbolt. Conclusions You post contains the following four questions. USB 1. David Anderson David Anderson I would love to know how the internal drive compares, if you wouldn't mind adding it alongside the other cases as a 'control'.

Not sure if it would similar or much faster than the X5 or what sort of bus it uses internally — Mr. Boy: I added some tables with respect to speed. I wonder why the read speeds for the external SSDs are faster than the write speeds, but the opposite was measured for the internal drive.

Open the System Information application on your iMac to get the type of internal drive. I assume this is what you meant by stating: "what sort of bus it uses internally ". I am researching this first : But basically Thunderbolt3 is give or take as fast as the internal SSD which means it could run off a primary external drive easily.

With my Mac mini, I have macOS installed on the internal drive and all the user files on the external Thunderbolt 3 drive. Another possibility would be to create a Fusion Container from two partitions. One partition would come from the faster internal drive and the other from the slower external drive.

The one part I am unclear about is how NVMe fits in. Is it anything to do with Thunderbolt or is it just a way of knowing an external SSD is fast enough to keep up with Thunderbolt's crazy 40Gbit speed?

There is no Thunderbolt 3 connector. Thunderbolt 3 and 4 use the USB-C connector. The statement "the USB-C connector and the Thunderbolt 3 connector look identical" is misleading, since it implies that those are different things. They are not. They don't "look" identical, they are identical. You're right. I will clarify that. Peter Cordes Peter Cordes 2 2 silver badges 10 10 bronze badges. Boy: On Samsung's web site, note that they break things down into 3 main categories: consumer, portable, and data centre.

It's the "data centre" drives that I'm talking about as being somewhat faster even for desktop workloads, at a big price premium. Thanks Peter that makes sense — Mr. Thunderbolt 1, 2, 3 and 4! As with USB.
