Which is faster USB 2.0 or SD card?
USB 2 max speed is 480 Megabits per second, or 60 Megabytes per second. USB 3.0 max speed is 5 Gigabits per second, or 625 Megabytes per second. So, in theory, an SD card with a speed of 95 Megabytes per second, such as a Sandisk Extreme Pro card (which I currently use) would be quicker with USB 3.
SD cards offer a higher storage capacity than most typical flash drives and for less cost as well. SD cards do come in 1TB capacities though they are generally priced outside an average consumer's budget.
A HDD will be faster than a USB or SD card (50MB/s) but it will be also more prone to damage because of the mechanical parts but most of the HDD's are sold in very hard and rugged casing but the HDD will last you about 3+ years if no damage done.

USB 2.0 vs. 3.0: Speed and More.
| Specification | USB 2.0 | USB 3.0 |
|---|---|---|
| Released | 2000 | 2008 |
| Transfer Rate (Speed) | 480 Mbps | 4,800 Mbps |
| Maximum Cable Length | 30 M | 18 M |
Class 10 is the fastest, suitable for “full HD video recording” and “HD still consecutive recording.” Class 2 is the slowest, suitable for standard definition video recording. Classes 4 and 6 are both deemed suitable for high-definition video recording.
Corsair Flash Voyager GTX has the fastest read speed, so it can also be considered as the fastest USB flash drive. Its read speed can reach 368 MB/s even tested by UserBenchmark.

Compact Flash vs.
Both SD and CF cards have their advantages and disadvantages. SD cards tend to be much cheaper than CF cards, but CF cards tend to be faster and more durable than the smaller fragile SD cards.
Adata's NVMe-based SD Express 7.0 card doubles UHS-II performance, and runs faster than a SATA SSD.
SD cards are best used for storing files and playing them back, while SSDs are optimized for running the operating system partition of a computer. One has a simpler role while the other needs to be smarter and more adaptable. It's not just a question of speed here but also one about workflow and versatility.
Which is faster SSD or micro SD?
An SSD is about 10x faster.
USB 2.0 is fine for that. On the other hand, if you want a drive for frequent use and speed is critical, particularly if you're transferring large files around, you'll probably want a USB 3.0 drive. Bear in mind that just because a drive is USB 3.0 doesn't mean it's all that much faster.
USB 2.0 can theoretically transfer 480 megabits per second (full bitrate 4k video is < 100Mbps I believe). The limiting factor is the speed of the hard drive and the ability of your TV to be able to read the content fast enough so that it doesn't lag.
USB 2.0 cables transfer data at 480 Mbps and provide power up to 500 mA.
UHS (Ultra High Speed) Card Classifications
Non-UHS SD cards max out at 25 MB/s, but UHS cards can work much faster. Currently, there are two types of UHS classifications: UHS-I Cards, which have a maximum theoretical speed of 104 MB/s, and UHS-II cards that allow for a maximum transfer speed of 312 MB/s.
Your transfers will still be slow. The fact is that while a CFExpress card can manage about 1,700 MB/s read speeds and the USB 3.2 spec can support that, the fastest mechanical hard drives will generally write to disk at about 170 MB/s, or about 10 times slower than the fastest cards.
SanDisk says the 1TB microSD card can achieve read speeds of up to 90MB/s.
Yes, you can boot your system from an SD card. Like booting from USB drive, you can turn to a powerful Windows media creation tool named AOMEI Partition Assistant Professional. Its “Windows To Go Creator” feature can help you to install Windows 11, 10, 8, 7 on an SD card, as well as USB flash drive.

Is a memory card the same as an SD card?
Memory cards are used to expand the storage capacity of mobile phones, SLRs, Dash cam, Drone and the other electronic products. Normally we refer to the memory card as SD card.
Adata also pointed out that is about 1.5 times faster than a standard SATA SSD. Compared to existing SD cards using the UHS-II SD and UHS-I SD interface, it's about 2.7 to 8 times faster.
In order to load and run Windows 10 or 11 from SD card, you can make use of AOMEI Partition Assistant Professional. This software can move Windows 10 or 11 onto SD card, make it bootable and then allows you to load Windows 10 or 11 from it on other computers, even the brand-new one.
Various microcontrollers and development platforms require you to install an operating system on an inserted SD card in order to use the device. The best example of this is the Raspberry Pi, it's pretty much useless until you put in an SD card with an operating system installed on it.
