I’m trying to determine the read/write cycle lifetime (or TBW) for the eMMC on my Raspberry Pi CM4. I understand that endurance can vary based on usage and eMMC size.
In my case, the eMMC part is KLMAG1JETD-B041 (16GB). I’ve already checked its datasheet, but it didn’t provide clear information on the specific read/write cycle limits or TBW for this model. I also assume it uses MLC NAND since this is mentioned on the product page from Arrow.
I’m aware of mmc-utils and that I can use it to read the CSD register for the eMMC Lifetime Estimation. However, this method seems a bit rough and doesn't provide a complete picture.
Could anyone provide more detailed information on the expected lifespan, read/write cycle count, or TBW for this specific 16GB eMMC module?
If there is no specific data available, is it reasonable to assume a 10,000 cycle limit, as commonly expected for other MLC NANDs?
Any insights or references would be greatly appreciated.
Thanks in advance for any help!
