$ sudo f3probe --time-ops ${path-to-block_device}

try on your machine

The command sudo f3probe --time-ops ${path-to-block_device} is used to perform a health check and estimate the true capacity of a block device, such as a USB flash drive or an SD card.

Here's a breakdown of the command and its components:

sudo: It is a command that allows the user to execute a command with administrative (root) privileges. It is used here to ensure that the f3probe command is executed with the necessary permissions.
f3probe: It is a command-line tool used to probe the capacity and integrity of a block device. It is a part of the "Fight Flash Fraud" (F3) project, which aims to detect counterfeit and fake flash drives.
--time-ops: It is an option used with f3probe to measure the time required for certain operations during the probing process. This can provide additional information regarding the device's performance and health.
${path-to-block_device}: This should be replaced with the actual path to the block device you want to check. A block device could be /dev/sdb, /dev/sdc, etc., depending on your system.

By running this command, the f3probe tool will analyze the block device specified by ${path-to-block_device}. It will perform several read and write operations to estimate the actual capacity of the device, verify its functionality, and detect any potential issues it may have. The --time-ops option will also measure the time taken for each operation, giving you further insights into the device's performance.
