WD external HD question

i need to get another external HD to store a bunch of videos and stuff on. I dont need it for backup i need it to actually store some movies and anime and stuff. I looked around and asked around and most people seemed to say western digital made decent external HD's. Some people said best bet is to make one myself but i have no desire to do that i just want to go out and buy something

the question is im confused on WD's versions. I thought i wanted their My book essential but theres like 2 versions out there

one they have on their main page here, the WDBAAF0010HBK
WDBAAF0010HBK

and another i cant seem to find on their main page but i can with a bit of digging
WDH1U10000N
http://support.wdc.com/product/spe [...] 10&lang=en
its also on their outlet page here
http://store.westerndigital.com/st [...] d.33956200

that ones called the essentials 2.0 or something along those lines.

what the hecks the difference between these? i thought the 2nd one was the elements i heard about but it doesn't seem to be the case

they also have the 2 on newegg

WDH1U10000N

same price. Can someoe fill me in on the difference between these? is one an older model or something? hell should i just look at the elements?

also, side question. I dont want any auto backup software. If i wanted to get rid of it should i just delete all the files on the HD or do i have to reformat it?

*edit* reading some revies it seems like maybe the WDBAAF0010HBK my book essential has manual backup software you cant remove? is this true?

ya i think im gonna go with one of their elements lines actually those have no software.. been hearing decent things about the sammy storystations though not sure which to go with
