190 times higher endurance than SSD disks
Since a month netPI is available in a 32GB byte FLASH memory version.

Time again to specifically highlight the extraordinary durability of the new 32GB SD card compared to SSD disk drives.

The 32GB SD card has an endurance of 1920TBW(Terrabytes written) or 1.92PBW (Petabytes written). This makes makes a ratio of 1920/32 = 60

Here is a collection of typical SSDs from the market and their ratio
  • SSD Western Digital - model number WDS250G2B0A with 250GB: 100 TBW and a ratio of 100/250 = 0.4
  • SSD Verbatim - model number Vi550SSD 49350 with 256GB: 150 TBW and a ratio of 150/256 = 0.58
  • SSD Samsung - model number 750 EVO with 250GB: 70TBW and a ratio of 70/250 = 0.28

This make a 190 times higher endurance in the middle than commercial SSDs. Dont believe? Have a look yourself to the appended SSD datasheets


P.S.: wanna have a high endurance SSD in your PC at home - buy a Intel Optane DC P4800X 750GB for incredible $2.500 ... just kidding

... but it has a just ratio of 41000/750 = 54.66 and relatively seen lesser than netPI's 32GB card for just $35 more.

Hello Armin,

tha sounds very good.

This means, with this new card, the NetPI is also suitable for small database application?

What I'm searching for is a long time data queue. In case we lost connection to host computer, we can pump the data into the database to roll them out from where after connection is established again. and also be able to aquire new data while rolling up the old ones.

Kind regards,

Carsten Oswald
Absolutely correct Carsten.

A time series database like InfluxDB which is available for free can be used from now on and store data locally on netPI.

Till this 32GB SD card is getting physically destoyed or damaged in its FLASH memory blocks you and I will be already retired.
