Still Fresh
So, I came up with this idea a few days back, but immediately dismissed it on basis that it was pretty silly to impliment. It keeps coming back, so I thought I would ask.
1) How difficult would it be to mount both SD cards as a single mount point?
2) If it could be done, would it provide any read/write speed advantages (ie: what is the bottleneck in the SD read/write, is it the SD cards themselves or is it the bus)
3) Are both SD cards on the same bus, or do they each have their own?
The idea, of course, is to get two identical (well, the same make and model) 8 GB (or so) SDHC cards, and link them to a common mount point. According to the Pandora, it now has 16 GB of data storage. You could transfer data to and from the USB port (again I wonder how fast that would be... maybe ftp would be the best idea there) to offset the fact that you (obviously) can't use the SD ports to transfer files.
The first cool thing that it would do is create a device with a single pool of data (like an eee, or even an iphone), so you don't have to worry about splitting your MP3 or movie collection. An added benifet may be an increase in read/write, but that seems a little sketchy. Could you convince the kernel to "raid" the two cards? Even if you could, would it provide any speed advantage. Or, you could partition your Pandora (but... why!) any other way you want to.
Of course you are taking a gamble on your data. If one of the cards fails, data on both cards are toast. All you would have to do is create a program to back up your data to say a network drive, or a even a desktop computer. That way if you wanted to upgrade your Pandora's "Flash Hard Drive" from a 16 GB to a 24 GB all you have to do is get a single 16 GB, reformat the two cards (again make and model problems may occur) and restore from backup.
I think that a modular SD storage system would be pretty cool.
Any thoughts or ideas about this would be appreciated.
