Is there a way to check the number of write/erase cycles my USB flash drive has, and the health of the USB flash drive? Is there a way to see the S.M.A.R.T status of the USB flash drive?

With CrystalDisk, you can see the health of your SSD/HDD. Is there a software like CrystalDisk, but for USB flash drives and SD cards?

EDIT: I forgot to ask what it means if a flash drive has 10,000 to 100,000 write/erase cycles. Does it mean that 10,000 to 100,000 files can be written and deleted on a single data block, before the data block gets destroyed?

Each data block can store only one file at a time, correct? What is the maximum file size a data block can store?


Win 11 Master
some of these tools might help =

not sure they can check write/erase cycles

HD Sentinel can't see anything about my Samsung USB flash drive.

The program/erase process causes a deterioration of the oxide layer that traps electrons in a NAND flash memory cell, and the SSD will eventually become unreliable, wear out and lose its ability to store data.

I can't nail down a size for the block size. I see 4mb but thats a windows thing, I can also find results for smaller.
Not sure it ties into allocation size in which case it varies based on size of the USB itself.
