OPi PCPlus eMMC testing utility?

[Christos]

Hi,

 

Is there any testing utility/exerciser for OPi PCPlus eMMC?

I'm geting strange problems when fast and large writes happen in eMMC.

 

 

 

/Edit

 

this is what I get by running 'armbianmonitor -c ~/healthtest'

appart from the "Average writing speed: 6.95 MB/s" is very low

..that final line is really alarming..
