Windows 10: A multiple drop in the speed of writing data to external media in the USB 3.0 connector Win...

Greetings.
After updating Windows 10 to version 1909, the bandwidth of the USB 3.0 port critically decreased on two computers.The speed of copying to a flash drive is on average 20 +/- 10 mb / s, instead of 100+ mb / s.Used drives:
external hdd Silicon Power
flash drive Transcend 256 GB usb 3.0
smartphone Lenovo Vibe X3 x3c50 with USB 3.0 interface
On these drives, the data transfer rate has always been stable at 100 Mb / s until the last update of Windows 10 1909.
Used computers:
Desktop - intel core i7 8086k, mb Asrock Z370 Taichi UEFI 4.20, 64Gb ram

Laptop - Gigabyte P35X v4 - intel core i7 5700hq, mb Gigabyte p35x, 16Gb ram

The problem is not in the drivers or components of the computers, but in the update itself.Two systems were not updated from September 25 to December 8, and after the update on December 9, these problems appeared.

Is it possible to fix this yourself?

USB 3.0 transfer speed drops to 0 only on one port. USB port and external drive are NOT defective.

I have a Dell XPS 13 laptop with two USB 3.0 ports. I connect a Seagate expansion drive to the left USB port and transfer a 4GB test file. It transfers about 1GB at 150MB/s and then transfer speed drops to 0. Then it picks up again after 3-4minutes, then
drops again intermittently.

I connect the same Seagate drive to the right USB port. The same 4GB file transfers with a constant speed of approximately 150MB/s. Thus the Seagate drive is not defective. Perhaps the left USB port is defective.

I connect a Sandisk 128GB flash drive to the left USB port (that is now suspected defective). It transfers the same 4GB file with constant 130MB/s speed, no speed drops!

Each step is reproducible 10x.

I am out of my wits here.

 

Silicon Power Releases eSATA/USB SSD Featuring 8x the Write Speed of the Normal USB

This is not a normal USB flash drive. Silicon Power has released the availability of its pioneering product: eSATA/USB SSD (eSATA; External Serial ATA), a high-capacity handy SSD in worldwide markets. The eSATA/USB SSD features eSATA and Mini USB dual interface, hot plug and play and four-channel high performance technology. The eSATA connection has a read speed of 92 MB/s and a write speed of 48MB/s, which is 8 times the write speed of the normal USB. The eSATA/USB SSD is available in 8GB, 16GB and 32GB capacities that are ideal for those wanting high-speed data transfer, high-capacity and portability.

The eSATA connector provides external data transfer at speeds up to 3Gbps, which is higher than USB 2.0 interface with 480 Mbps. It is very convenient for large volume of data transfer at a short time. The bottom of the eSATA/USB SSD is a Mini USB connector offering a read speed of 33MB/s and a write speed of 25MB/s.





With the advent of eSATA technology, most of the desktops, servers and laptops manufacturers start to employ eSATA port as a standard interface. Nearly 60% of new laptops uses eSATA interface. There are two kinds of eSATA port (with power provided/ without power provided). Users need to confirm which kind of port is on your device. If your eSATA connector is with power, you can plug it directly without connecting any cable. If not, users connect Mini USB cable to eSATA/USB SSD first, and then connect USB to the device.
