The USB Implementers Forum revealed this week that its nearly two-year-old specification for USB 3.2 will become a reality in 2019, doubling the performance of USB on new PCs this coming year. The bad news? This group of idiots is making USB even more complicated than before, too.
As you may know, USB 3 today is split into two different connection types, the classic “full-sized” USB 3.x Type-A port and the newer, smaller, and reversible USB Type-C, or USB-C (for “compact”), port. From a data transfer perspective, USB 3.0 originally offered 5 Gbps data transfer speeds over the Type-A port only, while USB 3.1 provides 10 Gbps of speed.

With USB 3.2, that performance will double to 20 Gbps, though, of course, your PC will need new hardware to achieve those speeds. And this performance is still half that of Thunderbolt 3, which is often utilized in at least some USB-C ports on modern PCs.
That’s all good. But the USB Implementers Forum makes Microsoft look like marketing geniuses when it comes to naming things. As part of the transition to USB 3.2, it is rebranding USB with new technical and marketing names, which range from unreasonable to ridiculous.
USB 3.2 will be called USB 3.2 Gen 2×2 internally, and USB 3.1 is being renamed, much less illogically, to USB 3.2 Gen 2. From a marketing perspective, you’ll see the new port described as “SuperSpeed USB 20Gbp” on new PCs, while USB 3.1 ports will be called “SuperSpeed USB 10Gbp.”
I guess USB 3.2 was just too simple and obvious.

<p>Reality is that USB-C is a joke. Nothing I have uses it. Nothing I have could even begin to use the speed. On my Macbook Pro I am forced to use a dongle for everything.</p><p><br></p><p>The fastest SSD's, (Samsung EVO 970 Pro M.2) have a max speed of 3.5GB/2.5GB which is above the 1.25GB you get with USB-A 3.1 speed. That said 99.999% of USB SSD enclosures are SATA which top out at .6GB. Even if you could get a M.2 enclosure for the EVO 970 you would need the same internal drive to even begin to transfer at USB 3.1 speed. People often do not get the fact to really use those speeds both sides of the USB connection need to be at or above the same speed. And those quoted speeds are best case/sequential/Benchmark test speeds. Average speeds for the EVO 970 are just at or below 1GB.</p><p><br></p><p>USB-C and USB-3.2 speeds are great. If you have some $5-10K M.2 SSD RAID storage tower and some really expensive 8K/4K video camera with a full USB-C connector then maybe you can use those speeds to download that video….maybe.</p><p><br></p><p>The rest of the world is just fine with USB 3.0/3.1 using a USB-A connector and will be for another 5-10 years.</p>
