A: Answer So here are a few facts that I understand after a little research: - any BLUE that are 2TB or more, are just rebranded GREEN (WD is removing the GREEN from it's product line). - there are no GREEN nor BLUE that run at 7200 at or over 2TB - GREEN have been around for over a year, but BLUE 2TB and over are new and were released this year (2015). again just rebranded green, so not new in design (firmware may be different but that would be true from a first released green and the same green sold a year later as well) -5400rpm is actually better than 7200rpm to keep them cool. also remember that data is more condensed so a one platter 7200rpm 500GB drive is probably going to be slower than 5TB at 5200rpm with 5 platters of 1 TB each (even faster if there are less platters, because it would be even more condensed) - if you want 7200 they will have to be the BLACK series, which is not found in MY BOOK, nor ELEMENTS. there is an expensive external one with black, just not those. -RED drives will only be found in Dual My Book, or network one lime my cloud, EX2, EX4. (there use to be chances of getting RED in element or my book , but seems like WD is being more careful now) CONCLUSION: this probably won't be a RED drive, but will be good 5TB green or blue which are more expensive without the enclosure and this is a great deal, this drive seems to be only sold at best buy and another store. and weirdly not on WD website. besides the 8sec head park timing (in green and blue) this is should be a wonderful drive.
