Well I uploaded and re-imaged first a HP t5710 thin client which has 512MB flash drive. It took 106 sec to upload the image and 204 secs to download the image to it. I was at first a little disappointed with the rates until I thought about the performance of the T5710 flash drive itself.
Next I uploaded an image from the wife’s desktop 640MB drive running Vista of which she is using about 225MB. The image upload speed with the Pogoplug/WD Elements system yielded a average transfer rate of 941 MiB/min or about 15.68 MiB/sec; so it took about 4 hours to upload the image.
After I ran these tests, I remembered that one of the switches between the Fog server and these two system is only 100M not gigabit so there maybe even better performance when using all gigabit network end to end.
This may not be a screaming eagle, but it is not bad either, for a minimal Pogoplug/USB drive system; which costs $112 (Drive=$89, USB Stick $8 and Pogoplug $15) I have a 2TB Fog server which consumes low power. I am a happy camper!!! Thank you folks for your wonderful work!!!
