However, with both S.M.A.R.T. and RoHS (Reduction of Hazardous Substances) compliance, the DT is still environmentally friendly to some degree. Like the other Spinpoint F1s, the DT is being promoted as having an improved performance. This is the result of both dual-ARM based firmware and the SATA native command queuing feature, which optimizes command execution. The DT differs from its Spinpoint F1 bretheren in the fact that it is a tiny 80 GB, with an 8 MB buffer memory. This is in the name of keeping the price down for users who want the features of the Spinpoint F1 series but do not need tons of memory.
