(Please trim inclusions from previous messages) _______________________________________________ Hi all,
If we are to use an external harddrive and an external USB Hub, why not get a mini-ITX MBO powered with 12V and a small mini-ITX box? This way we can have a decent CPU which is also low power in electricity not low in computing power (about 30 watts total).
I think the RPi is only good in portable apps, but then again the SD Card is a major handicap. It could be good for applications that are not 24/7/365, such as an event where an AMPRnet GATEWAY is desired only for a few hours or maybe a few days max. If you operate the SD Card for more than a few days, it might get destroyed from the constant write of log files, updating databases etc.
Can we have a system with no writting on the disk all the time? I'm not sure.

With a little configuration one could probably put everything except the boot configuration on an external drive and never write to the SD.

Hi Jerry,
Perhaps both my Kingston SD Cards were crap then. What make is your 128GB SD? But still you need an extra USB HUB which makes it unatractive for me.
Hi Demetre.
Have you studied the Compatibility list... Some are shown to be a bad choice.. Some Kingston are listed as such.
My first two SD cards I got from Fry's Electronics and they were I think, PNY brands. PNY I have found even their USB Sticks are junk.. But the two I got were only $4 ea.. Bad choice for the Pi. One lasted a few weeks the other until I had a sudden power outage about 6 weeks into it.
I now have 2 Kingston SDXC Card 128GB Class 10 SDX10V/128GB Running on TWO pi.. Or Pi Squared.. lol
One is under heavy abuse.. I have tried experimenting with sudden power outages, and constant read writes on one unit... And it has not suffered any issues.. In Fact I even tried it from -20F to +140F for S&G's They are NOT OVERCLOCKED.
The other runs w9hu BBS Linbpq..
What do you use to image the SD card I used to use Windows program WinDisk32 .. I think this is the biggest issue with the Pi SD Cards..
At least I have had no issues with mine since I stopped that practice.
Also what are you using that requires an external HUB.. You can also connect a TNC (other serial devices) to the GPiO port instead of the USB. Have you tried a PiTNC yet? Makes good topping.. :) it is the same size and sits atop the Pi. Like Icing!!
