Difference between 2 samsung SSDs

[RTsteak]

Hey there,
I'm looking at 2 samsung ssd's:
Samsung: MZ7GE960HMHP (960GB) - price: $799.99
http://www.newegg.com/Product/Product.aspx?Item=N82E16820147368

SAMSUNG 840 EVO: MZ-7TE1T0BW (1TB) - price: $429.95
http://www.newegg.com/Product/Product.aspx?Item=9SIA2W014B1465

from the specs of both i find the EVO sould perform better(or i'm missing somthing)
why the "MZ7GE960HMHP" is much more expensive?

The more expensive one is billed as "Enterprise" and "Data center series." Designed for non-stop use and mission-critical reliability.
Enterprise grade drives are typically more expensive in HDDs, too.
