The Red Pro is absolutely “good enough” in the sense that the build quality is very good, even better than the Green series. It’s just that many of it’s extra features are specifically for RAID and NAS setups. If you strip off these extra features you basically have the Black series.
Also, in the case of a bad sector, discs specifically for RAID setups (like the Red Pro) will stop trying to read very quickly, because a similar data is available in another disc in the RAID. A “standalone” disc like Black and Green will try much longer to get the data from that sector, reducing the chance for losing the file.
The reason I suggested the Green instead of black is the use you specified. When it comes to streaming music or video to you TV or stereo, the Black won’t make a practical difference, and the Green runs cooler and quieter. However in the case of harder workloads, like video editing, the extra power of the Black’s comes handy.
In you case I would rather spend the money on two Red (non-Pros) in a RAID 1 setup (mirror), this will save your data from a potential harddrive crash.
So, the bottom line is that you can use the Red Pro as a standalone disc, but it won’t help you more than a Black.
