Vero 4K NAND Lifetime writes

Hello,
out of curiosity I did this on my vero 4k bought in July, 2017:

root@vero4k:~# dumpe2fs /dev/vero-nand/root | grep -i write
dumpe2fs 1.43.4 (31-Jan-2017)
Last write time: Thu Jan 1 01:00:09 2015
Lifetime writes: 1561 GB

Frankly I am a little bit scared now.

Is this for real? I have no idea, how I managed to write so much data to the disc:

root@vero4k:~# df -h | grep root
/dev/vero-nand/root 14G 2.3G 11G 18% /

Do I have to look for a new device ASAP?
Or is “dumpe2fs” simply just showing some dumb fake numbers pulled out of the … because it is not working / has issues with the Vero 4K?

How much data can you write to the internal NAND/eMMC before it breaks?

Any ideas?

Thanks for letting me know.

In theory, that’s the amount of data written to the EXT4 partition since you last reinstalled OSMC. It’s possible that you have never reinstalled the device since you got it.

But I’m not so sure that I trust that metric.

The figure might seem high but it’s only 100 times the eMMC size. I know nothing about the eMMC chips used on the Vero4K but a quick look around suggests that many eMMC devices can accommodate 3,000 write cycles.

The high figure might be related to write amplification, ext4 journalling and perhaps some other file metadata being written. (FYI, I reinstalled OSMC on my Vero4K in March 2018 and it’s currently showing 1177 GB.)
