I used the command cat /sys/block//mmcblko/device/name and found that the eMMC model is G1M15M, with a write speed of only 15.7 MB/s. Then I checked another eMMC, model DG4064, which has a write speed of 46.9 MB/s.

Based on the context provided, it seems that you are comparing the write speeds of two different eMMC models: G1M15M and DG4064.
The G1M15M eMMC model has a write speed of 157 MB/s, which is the one currently being used in your Jetson AGX Orin device. On the other hand, the DG4064 eMMC model has a significantly higher write speed of 469 MB/s.
Comparing the two, the DG4064 eMMC model has a write speed that is approximately 3 times faster than the G1M15M eMMC model. This could potentially lead to improved performance in applications that rely heavily on disk I/O operations.
However, it’s essential to note that the actual performance difference between the two eMMC models may vary depending on the specific use case and system configuration. Other factors such as the device’s processor, memory, and software configuration can also impact overall system performance.
In the context of the provided information, there is no direct mention of the eMMC models or their write speeds. However, the discussion about disk encryption and partition layout suggests that the device is using a Linux-based operating system, and the flash tool is used to generate file system images and flash them onto the device.
To take advantage of the faster write speed of the DG4064 eMMC model, you would need to replace the existing eMMC module with the new one. However, before doing so, it’s crucial to ensure that the new eMMC model is compatible with your Jetson AGX Orin device and that the necessary software and configuration changes are made to support the new eMMC module.
In summary, the DG4064 eMMC model has a significantly faster write speed compared to the G1M15M eMMC model, which could potentially lead to improved performance in certain applications. However, it’s essential to consider the compatibility and configuration requirements before replacing the existing eMMC module.

I’m not trying to compare the write speeds of two eMMC chips. Rather, two identical AGX Orin 32GB modules show different eMMC chip models when read, which results in different write speeds. Can you tell me why the same module would have two different eMMC chips?
Please provide the parter number of your modules and JetPack SW version.
AGX Orin 32gb and jetpack5.1.5
Part number?
2. By scanning the module’s QR code, you can check that the eMMC part numbers are different.

Hi,
Could you please try the two modules on developer kit with latest Jetpack 6.2.1 r36.4.4? Would like to know if the issue is present on latest Jetpack release.
