How do I test my SD card speed?
Test your SD card speed here.
Download and open one of the SD speed tester programs below, insert your micro SD card into your Computer*, select the drive containing the SD card, and hit start. Run the test a few times to make sure you are getting consistent results.
Does the speed of SD card matter in Raspberry Pi?
The speed of an SD card will also directly affect how fast your Raspberry Pi runs, in just the same way as the speed of a hard drive affects how fast a conventional desktop computer runs. The faster you can read data from the card, the faster your Raspberry Pi will boot, and the faster programs will load.
How do I test my SD card?

How do I know if my Raspberry Pi SD card is working?
Therefore, if there’s no green light on your Raspberry Pi, there’s a problem with the SD card. Meanwhile, PWR blinks when power drops below 4.65V. As such, if the Raspberry Pi’s red light doesn’t light up, there’s no power.
What is read speed on SD card?
SD card speed, or the speed at which the card can read and write data, has significant implications for your project workflow. Most cards list their read and write speeds on their label. For example, the Extreme PRO UHS-II SDXC cards can reach a read speed up to 300MB/s, and a write speed up to 260MB/s.
Why is my micro SD card so slow?
A SD card will only slow down the OS if you are running apps from the SD card rather than from internal memory. If you have saved apps to run from the SD card then the OS has to constantly read/write to the SD card. The majority of SD cards are slower than the Internal memory and are less secure.

Rated speed
It’s represented in MB/s (megabytes per second), or a large number followed by an “x” — or sometimes both. The “x” designation is a marketing term: 1x represents 150 kb/s, so 600x is the same as a 90 MB/s rating (600 x 150 = 90,000).
