I think he said it's working fine on his pi2 and failing on windoze.
@rupy, I know nothing of windows, can't help you. But as you said, since this thread is about bitcoin on raspberry pi, maybe you should start a new thread.
it keeps crashing on mine tho :/, running latest raspbian
Right, I sholuld admit, I saw a post from gmaxwell in another thread talking about how bitcoin-core is probably not going to run well even on the pi2. This is above and beyond all the disk writes to your sandisk. I haven't tried it myself. Out of curiosity, though, what's the error you're getting on the crash?
Alternatively, you can use a board which supports mSATA like the Banana Pi or Hummingboard, which enables you to plug in an mSATA SSD for more storage. SSDs are very cheap now compared to the earlier years.
