Performance Implications of Whole Disk Encryption

Recently, the Inforwarrior list sent me a notice of Seagate announcing a hard disk that offers full-time, whole disk encryption.  For the right need, this seems a solid product that will perform better than software encryption. Here (2nd URL) is another article on that device. I've always been concerned with rapid response time, so the current rush to encryption may cause it to be overused, with negative performance implications for most users. This (3rd URL) article is solid in covering encryption and notes well the performance hit.
