We ran the same test as above using the SanDisk MicroSDXC card for Nintendo Switch. microSD card: Taking what we knew about SD cards, we applied the same thinking toward microSD cards, which are used less frequently these days and are naturally slower.WeвЂ™ve measured read and write rates with this card at 93.78 MB/s and 84.58 MB/s, respectively, in other tests with these hubs, the fastest read speeds were about 89 MB/s, and write speeds reached 75 MB/s. We ran AJA System Test on a 64 GB SanDisk Extreme Pro, the fastest UHS-I card we tested in 2020. Since SD cards are less commonly used than USB ports these days, this feature isnвЂ™t as important. SD card: Photo and video files can be quite large, so with a fast SD-card transfer rate you wonвЂ™t have to wait around to import a dayвЂ™s worth of shots from your card.WeвЂ™ve found the Power tab in macOSвЂ™s System Report to accurately report the wattage of the power source, and in our tests we compared the figures stated there against what each company advertised. USB-C supports power at up to 100 watts, while laptops take anywhere from 30 watts (for a small machine such as the MacBook Air) to 45 watts (for many midrange laptops, as Chromebooks tend to be) to 97 watts (for the 16-inch MacBook Pro). Power pass-through: All the hubs we considered also have a USB-C port that allows you to plug in your charger without taking up a second port on the computer itself (if it even has a second port).Operating temperatures between 86-122 degrees Fahrenheit вЂ¦ are normal.вЂќ We didnвЂ™t measure anything at or even close to 122 degrees, but we would have disqualified any model going over that temperature as a safety hazard. As a representative from Satechi (a prolific hub and accessory maker responsible for one of our former picks) explained to us: вЂњAll the bandwidth that goes to Ethernet, HDMI, USB and SD card ports requires energy consumption and thatвЂ™s transferred to heat. Heat: Because hubs and adapters can get hot during use-especially, judging from our experience, when Ethernet is in use-we also measured the temperatures of our picks with an infrared thermometer after 15 minutes of continuous data and Ethernet use to make sure they werenвЂ™t dangerously hot.

(Note that unless you have reliable Gigabit Ethernet service, you wonвЂ™t be able to measure if the port is actually performing at full speed.) For each model in the test group, we verified the connection speed in Network Utility on a Mac, which displays the maximum link speed. Most hubs with Ethernet ports support gigabit speeds, meaning data can transfer at up to 1,000 megabits a second.

Ethernet: A wired Ethernet connection is almost always faster than Wi-Fi and is more reliable, too.

Most hubs support only a 30 Hz refresh rate (the image refreshes 30 times a second) at 4K resolution, but a handful now support a smoother 60 Hz rate, and we prefer those hubs that do. We connected each of the hubs via HDMI to a Philips 272P7VUBNB/27 monitor with the resolution set to 4K, and we used the Blur Busters UFO Motion Test to confirm the refresh rate.

HDMI: A hub can be very useful at a desk, especially if you want to hook your computer up to an external monitor.

Our measured speeds landed largely in the 400 to 425 MB/s range we eliminated any model that was noticeably slower. Most of the hubs we tested advertised USB 3.0 speeds, which max out at 640 megabytes per second on paper. Since SSDs are faster than spinning hard drives, our use of the T5 ensured that the speeds we measured werenвЂ™t hindered by the drive.

We ran AJA System Test speed tests using the Samsung T5 Portable SSD (500 GB) to measure transfer speeds. USB-A speed: Although USB-A ports generally donвЂ™t support data-transfer rates as fast as those of USB-C or Thunderbolt 3 connectors, itвЂ™s still important to be able to transfer data quickly.Two USB-A 3.2 Gen 1, one USB-C 3.2 Gen 1, one USB-C power Two USB-A 3.2 Gen 2, one USB-C 3.2 Gen 2, one USB-C power Note that the Anker 10-Port 60W USB 3.0 Hub ships with only a USB-AвЂ“toвЂ“USB-B cable, so youвЂ™ll have to buy a separate USB-BвЂ“toвЂ“USB-C cable to connect it to many modern computers. As a bonus, itвЂ™s aesthetically inoffensive-it doesnвЂ™t look like it belongs with the greatest hits of ugly вЂ™90s technology, unlike some of the other hubs weвЂ™ve tested. It has seven upward-facing USB-A 3.1 Gen 1 data ports with a helpful LED activity indicator for each it also has three 12-watt (2.4-amp) power ports just for charging. If youвЂ™re mainly concerned about connecting to your computer as many devices as you can, choose the Anker 10-Port 60W USB 3.0 Hub.
