Data Pads Bonus?

Is there any bonus for getting all the data pads in Reach? I read them all online and I never went to get them because there was no achievement for them. Has anyone got them all and if so does it unlock anything?


Some will thereoize reading all data pads, killing all BoBs, on LASO with melee only full campaign would do something because the GRB helemt is like a BOB helmet from Marathon.

But their flippin nuts. Lol.

I was wondering about that Helmet. I would think you unlock something.
