Hardware: No
Software: Yes
Hardware: Because data encryption is performed at the end of the write path, storage efficiency mechanisms are not impaired.

Software: Because HyTrust and Vormetric are end-to-end solutions, encryption is performed at the start of the write path and some efficiency mechanisms (eg. deduplication and compression) are effectively negated.
