Western Digital color codes their drives for different functions as they are physically built differently for what they are intend to to be used for. High reads/low writes, Low writes/high reads, always left on, etc.

>Reds are for NAS/RAID set ups
>Purple are for camera systems
>Greens are more silent and energy efficient(chart is old and they stop making those years ago)
I forgot what Blue and Black are for but I think those are for PC. As for your question, it helps to know that WD went retarded with the Red's. Years ago they physically changed them without telling customers. I forgot the full details but the short story was they were trying to cut cost and in return made the normal Red's shit the bed when ran inside NAS or more importantly, they suck in a RAID setup. Instead of doing a recall, WD decided to continue selling those and came out with WD Red Pro at slightly higher the cost, which are better for RAID set ups. Normal Reds are fine for 1HDD set ups, just not for RAID.

tl;dr get the Red Pros if you want to use a NAS, its probably fine to use as a single drive for awhile. I don't know about the Read and Write speeds though.
