if it works finally locally attached to your network, then your most likely bottleneck is your internet upload and download speeds-in both directions where you up and down speeds typically are something like 8 mb down and .5 mb up.

Locally attached, the gig NIC port and USB 2.0 ports(with a spinning 7200 SATA drive) on the Pogoplug can achieve normal speeds of up to 30 megabytes per second.

the Pogoplug is NOT a high speed file serving device. it;s a media streaming device. copying of whole files won;t happen too fast. streaming of video a little bit at a time does work though.

the other part to the equation is the upload/download speed on the client end. if the upload speed at the server end is 1 megabyte per second then the download speed at the client end will never exceed that value. you only get the lesser of all values.

also, i don;t think traffic is routed through PP servers. I think it just uses PP servers for location services. i think I heard that the pogoplug client uses a ipV6 tunnel to make the connection. with any level of encryption, its going to slow you down.

your best bet for pure file transfers is to use FTP but that;s not something Pogoplug supports without hacking.

sounds like the transfer is timing out or is getting broken. unfortunately, i don;t think there is any easy answer for this. it;s not like the pogoplug device or service supports anything to resume broken transfers. i can;t really speak about the cloud service, it;s new and I haven;t used it alot.

but for local transfers, i usually don;t have issues transferring files to a wired PC-i;ve transfered files up to about 2 gigs or so to a 7200 rpm spinning hard drive connected via USB. but to my cell phone, it doesn;t work too well with large files-to be expected because transferring with wifi introduces another source of contention plus trying to read/write to a class 4 sd card is not going to fast either.

another thing people need to consider-USB and SATA interfaces don;t multitask all that well. so any operation to these drives will use the Host CPU and multiple requests will not perform all that great. maybe a 1 for 1 transfer will be okay. but large transfers and accessing simultaneously from different clients will experience problems like timeouts, ect....

while i;d love to think the modern linux OS running on a ultra efficient ARM processor would be a killer platform the CPU and limited memory on these units are not all that powerful to begin with.

the Pogoplug is designed for streaming little bits of data at a time. the designers made a calculated decision to install as powerful a CPU/memory(very limited)as necessary to do this type of operation.
