@dgelessus @Phuket2 thank you for your guys responses^_^, I am clear about the pythonesta ability in data analysis now. And I will drive my RMBP for major heavy work. And make my iDevices only work with simplified dataset from raw data.

I am processing a lot of data. HDF5 with compression filter is helpful for doing such thing, without compression, I have 50GB data for storage; HDF5 makes it 7GB.

Looking forward to do "import h5py" in pythonesta.

Here is the github for HDF5
