data transfer speed

Apple’s new 10th-Gen iPad finally brought a new design and a USB-C port to the company’s low-cost tablet (although the Lightning-equipped 9th-Gen iPad is still available). But the USB-C port isn’t all it’s cracked up to be. Aside from not working with the first-gen Apple Pencil — which bizarrely is the only Apple Pencil that works with the 10th-Gen iPad — the USB-C port is also slower than other USB-C iPads.

The Verge noted as much in its review of the new iPad, and a ‘Max Tech’ YouTube video (via MacRumors) demonstrates this as well. In short, the iPad’s USB-C port is limited to USB 2.0 speeds (up to 480Mbps for a data transfer). Not only does that make it the slowest USB-C port available on an iPad, it also means the new 10th-Gen iPad offers the same data transfer speed as the 9th-Gen iPad’s Lightning connector.

MacRumors notes that the iPad Pro models with the M1 chip offer Thunderbolt 3 and data transfer speeds of up to 40Gbps, while the fifth-gen iPad Air is capable of up to 10Gbps. The fourth-gen iPad Air and the latest iPad mini both support 5Gbps data transfer speeds. Moreover, Apple doesn’t mention the speed limit on the 10th-Gen iPad’s spec page.

Depending on what you want to use the new iPad for, the data transfer speed limit may not matter much. I imagine most people buying the 10th-Gen iPad just want a tablet for media consumption and games. Those looking for something for productivity or to replace their laptop likely will want the iPad Air or Pro, both of which offer much faster transfer speeds.

At the same time, given the price increase the 10th-Gen iPad got, it’s frustrating to see these small limitations, which ultimately serve to make the 9th-Gen iPad better value (even though Apple also raised that iPad’s price).

Several new USB-C identification symbols for cable and port packaging just dropped. Companies can use the symbols to help consumers tell which USB-C cables, ports and charging bricks can do what.

The USB Implementers Forum (USB-IF), a group that maintains the USB standard, created the new icons, which work alongside the USB4 and 240 watt (W) power standards.

While ultimately it’s good to have symbols to help identify which USB accessories can do what, the new icons exemplify an ongoing issue with USB-C: it’s confusing.

USB-C was supposed to be much simpler. One port to rule them all, everything just works, etc. Except, that’s not the case.

Seasoned tech veterans likely won’t have an issue here (the new identification symbols generally do a good job communicating what a cable can do). But for those not immersed in the tech world, trying to figure whether you need the USB4 40Gbps cable or the USB Type-C 240W cable or the one that does both (or the one that does neither) could be confusing.

The Verge points out that the new branding ties into the USB Power Delivery (USB PD) 3.1 specification announced earlier this year, which confusingly lives under the USB Type-C Release 2.1 specification. Ultimately, all these things are trying to communicate the power level that cables and charging bricks can deliver, now up to 240W with the correct cable and brick combination.

I would argue that having identification symbols is better than not having them. It’s also arguably better than having several different port types, although in many cases, people still need USB-A, HDMI, DisplayPort and other kinds of ports (we are definitely not in a one-port world yet). And don’t get me started on the variety of proprietary charging hardware from laptop manufacturers that use the Type-C port but don’t fall under any USB spec.

When you compare to another specification that uses the USB Type-C port — Thunderbolt 4 — it’s clear that USB is much more confusing. Anyone shopping for a Thunderbolt 4 cable just needs to look for the Thunderbolt 4 logo, and then they know it can handle everything in the specification.

To me, that’s the ultimate solution — one standard that works for everything I need. Charging, video, data transfer, etc. Maybe USB will get there one day.
