In the news at that time, I complained about the naming rules of the standards development organization USB-IF. Together with USB3.2, which is currently being implemented, there are three standards in total. After the name change, they became USB3.2Gen1 and USB3 respectively.

I don’t know if you still remember that Tuizai once talked to you about the news about USB 3.2. At that time, in the news, I complained about the naming rules of the standards development organization USB-IF.

They renamed all current USB 3.0 and USB 3.1 to USB 3.2. In addition to the USB 3.2 currently being implemented, there are three standards in total. After the name change, they became USB 3.2 Gen 1, USB 3.2 Gen 2 and USB 3.2 Gen 2x2. They are almost the same as the names of the new generation processors of Intel next door.

Of course, the standards have been updated, and various manufacturers will develop their own products according to the standards, and one of the most critical links is the main control chip . At the Taipei Computex, Xiangshuo showed its own USB 3.2 main control, the plan they announced at that time included two parts, one was the XHCI main control chip and the other was the PCIe bridge chip.

At that time, they expected that the first products supporting USB 3.2 Gen2x2 would be available in two years.

Phison, as a major master control manufacturer, has not been able to grab the first launch of USB 3.2 master control, but this does not prevent it from continuing to follow the new standard as an established manufacturer.

Phison Electronics announced just a few days ago that they are developing a controller that supports USB 3.2 Gen 2x2, model "PS2251-17", for high-performance external portable SSD.

Phison’s main control supports two NAND flash memory channels and 16 CEs. It can be used with 3D TLC and 3D QLC flash memory from various manufacturers. The system interface can be Toggle 3.0 and ONFI 4.0, and supports Phison’s fourth-generation LDPC school. verification, RAID ECC error correction, SmartZIP intelligent compression, AES-256 encryption and other technologies.

As for the main control performance, Phison claims that this main control can allow portable SSD to achieve ultra-high performance of 1.3GB/s continuous reading and 200K IOPS random reading. Compared with USB 3.1, it has achieved a qualitative leap, but the actual product The performance also depends on the flash memory specifications and the manufacturer's specific configuration.

Phison plans to trial-produce PS2251-17 master control in the fourth quarter of this year, and portable SSD products based on it will be available in the first half of next year.

has something to say here. I know that the next-generation Xbox Scarlett and PS 5 do not support USB 3.2. Students who have used these two products know that the much larger capacity in their machines does not exist. It's not enough, especially now that digital versions of games are so popular.

If the interface of the future host can support USB 3.2, it will be like good news for most of us players.
