Good question bitcube. Currently I am not happy with the fact that it doesn't save a folder structure. You can specify a folder with sub-folders and it only saves the files, but not the folder structure. I'm sure that is planned for future revisions but it would be a negative for some applications now.
Upload and download speeds are not breathtaking but I'm assuming that will improve as more hosts come into the network. I was doing the uploading during the peak time that everyone was installing the new GUI version, I assume that was slowing down things a bit. Its definitely not the type of speed you would get from a locally installed NAS at the moment.
As for the pricing I started high at 4500 SC (0.005895 BTC) per TB per Month for hosting around 2:00 AM yesterday and today I have 7 contracts. I need much more to fill up the 5 TB I'm using, so will likely start lowering the pricing over the next few days to find the most suitable pricing per TB. Current figure would work out to about 0.000005895 BTC per GB. I saw a Google estimate of them charging 0.00039 BTC per GB per month. So there's definitely room for healthy competition.
So right now I guess the strategy would be to offer great pricing to capture market share.
Note: I recalculated the numbers above after the original reply, due to having used the incorrect monthly price per TB.
