Differences Between SD Card vs. USB
SD card
Similar to flash drives, SD cards come in many shapes and sizes. Just like The Godfather, there are five families of SD cards, each with its own storage capacity limit. One is SDIO (Input/Output), which doesn't deal with data, but here's another one.
First comes the Standard Capacity SD card, which can usually hold around 2GB of data; then we have higher High Capacity SD up to 32GB; beating that out of the park is the eXtended-Capacity SD card, holding up to 2TB; then the SD Ultra Capacity went up to an amazing 128TB! Here are the data rates for each.

For example, SDUC cards can only be used in SDUC devices and not in SDXC devices. Most devices have a format for SD cards, the smaller format can be inserted using an adapter.
Physically, SD cards have thinner and flatter platforms compared to USB drives.
Like USB drives, SD cards have no moving parts making them stable. Because of their small size, however, especially microSD, they are often lost or misplaced.
Just like USB drives, SD card life is measured by write-and-seek. This refers to the number of times the data is copied to the storage device after deletion. Most have a life of around 10,000 write cycles.

Flash Drive
Flash drives are usually much faster than SD cards. While even high-end UHS-II cards max out at 312MB/s, standard USB 2.0 drives just start at 480MB/s! Now, let's look at the data graph. Compared to SD cards, I'm sure you'll be amazed by what you see here
The small but powerful storage device is also flexible, offering forward and backward compatibility with any USB standard supported by the device to which it is attached.
For example, a USB 3.0 capacity flash drive will work with devices that support USB 2.0. Likewise, it works with devices that support USB 3.1. In addition, flash drives are compatible with any device with a USB port, regardless of the operating system.
The transfer speed of a USB drive depends on the USB standard of the device, but the actual speed will be slower. Below are the corresponding speeds for various USB ports in use today.
