In terms of cost per GB, I think they are some what competitive compared to other solutions out there (AWS/Azure).
Price isn't their only strength either-- They provide incredible user support along with all sorts great resources for managing large storage systems without it becoming overcomplicated! Their ability manage data easily within my accounts has been very useful in allowing me access more quickly than if we used tools like 3rd party softwares or cloud providers would allow us too do so safely & at such scale as well!! They are very good at what they do, with fantastic customer service! I have been using them for over 10 years now, first as my ISP provider back in 2000/2001 when it was called NAP before becoming AT&T (now CenturyLink). Then later we switched to their managed services which has worked great since then. Very reliable network infrastructure that can handle any amount of data traffic you throw its way without breaking down or slowing to crawl like most other networks out there.
