powershell - SharePoint - document libraries, lists, views and number of elements -

i have lot of documents want store in document library in sharepoint 2010. we're talking 50k+ documents. i've worked document libraries many times, not of size , find myself getting confused definitions when comes how these should stored , number of elements allowed.

by looking here: http://technet.microsoft.com/en-us/library/cc262787%28v=office.14%29.aspx#listlibrary says document library can hold 30 million documents. nice! 50k not close 30 millions. however, can dump of documents library without grouping them in views or sub folders? cause view can have 5k elements , have create views , put documents in many views in order not exceed limit.

now, documents, , library, never browsed going library. each document linked place, , not often. therefore kind of hoping can dump documents in 1 big library. have read if number of elements in list exceeds 5k sharepoint not query query return everything, instead exchange query default query. in case fine, there other concerns dumping many files 1 library in sharepoint 2010? , there else may not have thought about?

also quick question @ end, planning on scripting upload using powershell, have heard others uploading documents way sharepoint takea lot of time because 1 document @ time. possible "bulk upload" documents through powershell or approach?

the key here understand sharepoint can store 30 million documents, can display 5,000 @ time. easiest way maintain dump documents separate folders no more 5,000 documents in each folder. easy that, i'm not big fan of folders since impose single organizational structure on set of documents. applying metadata , filtering views more efficient in long run, harder when dumping documents library. suggest looking @ of third party migration software can kind of bulk upload , still maintain appropriate metadata. 1 i've used (there others) metalogix content matrix.
