I like the IRC too, but I worry about losing valuable tips and links that were passed around, unless of course transcripts are archived, but that is probably too much of an ask.

Re: Physical design

<t>I would love it if on Model B, the USB connectors weren't stacked vertically, but I assume they are stacked that way due to space constraints and that the combined height doesn't exceed the height of the RJ45 jack.<br/> <br/> If horizontal space isn't a constraint, it would be nice to lay the two...

Sata would be nice, but the R-pi doesn't come with it :P


My point exactly :) Depending on your application needs the Raspi may or may not be suitable to serve storage.

Re: USB/NAS Enclosure

Not sure what your application setting is, but you might need SATA-type performance which the Raspi cannot, if the data it serves has to go through it. (Again, I don't know your requirements.)

We're probably drifting away from the Raspi here, but I wonder if it is worth getting a hybrid HDD (such as the Seagate Momentous) for virtual memory.

The power supply is a set of SMPS plus LDO protected by a diode against reverse powering.


Are you saying a PSU is included with the device? Please clarify. Thanks
