EV WORM device suggestion for

Hello,

I am hoping for some suggestions on the kind of WORM hardware that is compatible with EV, for an Office < 100 employees and with email volume < 75-100GB/year.  I have experience with NetApp SnapLock but it seems to be an overkill for the above requirements and I am hoping to hear what other shops do.

Thanks in advance,
