I've been doing some testing with the media id utilitly posted recently and noticed that the ESbuy.com and Smartdisk media are both from one company RITEK. Further search shows that people on EBAY are selling 50 packs of RITEK media for around 80 dollars for a 50 pack... BUT they are silver media (ESBuy=gold, Smartdisk=purple)

This leads me to think that perhaps the silverunbranded that esbuy sells is also indeed RITEK but I do not know for sure... I'm thinking of ordering a few and finding out... I'll let everyone know what I find... has anyone used the ESbuy silvers? I know the normal esbuy has worked great for me so far....
