The Raspberry PI thread got me thinking.

I need a "portable PC" that can do high-speed USB-3 i/o.

I've been using a laptop with both USB-3 ports and a eSata port. I would like enough horsepower I can run compression on the data stream.

Effectively "dd if=/dev/sdb | gzip > compressed_image_file" (I actually use ewfacquire from the distro to do this.)

My plan is to buy a new laptop, but a nice Arm box might be a much better choice.

Especially if I can get one for under $200. I could buy 3 of those instead of a decent laptop.

Any suggestions of what I should look at?

Thanks Greg -- Greg Freemyer

The Pi 3 is USB 2.0 only. Maybe this one meets your needs: http://www.eetimes.com/document.asp?doc_id=1328716&page_number=7 It also has 2 USB 3.0 ports along with its single USB 2.0 port. For connecting to the internet is has a Gigabit Ethernet port and an HDMI port for a display. If not, that page is part of an article that covers many others. -- After all is said and done, more is said than done. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

Those requirements are rather more similar to the minipc I mentioned on that thread. It has 4 USB3 ports, and one internal SATA port (laptop disk size), plus another mSATA for SSDNow. As for price: 165€ the box, plus 58€ the memory, 52€ the SDD. Add keyboard/mouse and display if needed. There are many similar boxes with variations in the hardware. Dunno about eSATA, but USB3 seems to be "the in" thing to have these days. If you want to measure i/o speed for your case, describe a command line that can emulate your workload and I'll test it. I'm not familiar with ewfacquire. -- Cheers / Saludos, Carlos E. R. (from 42.2 x86_64 "Malachite" at Telcontar)
