Hi Mike

 

I run everything from a hard drive as the SD cards fail regularly

Hi All

 

A few weeks ago I moved my Cluster over to a RPI4 where it hums along nicely.  

 

I know from many weather stations that the SD card will go into a read only state in about 6-9 months as writes start to fail.  Running IOTOP tells me what we do significant writes to the card.

 

Does anyone have a list of things they do to minimize the writes?  

 

On my list I have:

 

1.	Turn off the swap space
2.	Move /spider/data to a RAM disk

Anything else?
