I now own six 14-TB Western Digital Red Drives that I use for raw storage. (Non-RAID.) 4 of which are the 5400 RPM version which is the WD140EFFX model and, unfortunately, I have come to find out that 2 are the 7200 RPM "WD Red Plus" model (WD140EFGX). I have slowly acquired these drives over the last few years from a few different sellers on Amazon and naively thought they were all 5400 RPMs. They were all listed as such, but I have come to find out various sellers mistake RPM versions often. I know I am quite the fool for not checking the model numbers 1st, but it is what it is and I think all drives are probably outside the return window. Only recently have I actually noticed that 2 are different models from the other 4. With all that, I have 2 questions:
1. I know that 5400 RPMs are generally considered more reliable for storage, but is the difference so great that I should be worried about replacing the two 7200 drives if I'm worried about long-term storage? My understanding is that recent drives show little difference in reliability between 5400 vs 7200 rpm versions or is this incorrect? They have been good working drives for several months now so I can't complain about current performance.
2. Is it safe to "mix" different RPM drives in the same hard drive enclosure? I have two 4-slot HDD enclosures and due to the time I have acquired each drive, each enclosure now has one 7200 RPM drive and the rest 5400. Does this matter? Should both 7200 rpm drives be in there own enclosure?
Thanks with whatever clarification you can provide.
