Is there any noticeable difference in speed between 2TB M9T and 3TB WD Red? And do any of your three M9T's make that random "beep" sound several people have commented on? Thanks.
I have never heard a beep or chirp on my 3x M9T, not saying it wont happen, but my guess depends on the setup and maybe the firmware of the hdds, to me 2.5 hhds have lost relevance, specially because there 2.5 ssd that have reached 2tb capacity, given that price is what still makes the difference, there isnt much interest on hdd manufactures on increasing their 2.5 offerings.
So its up to you, to me its an easy choice, if i have the space for 3.5, i would go with WD Red 3tb, it has been reviewed by SPCR and gotten the editors choice, and there are a lot of of SPCR users that have bought them with good results/feedback, there are no silent mechanical hdds, but under my conditions its not perceivable, but remember not all setups are the same, we all have different placements, ambient noise, hearing, preferences and tolerances.
That said, if i were not to have the 3.5 slot available, let say im building on mini itx something like the Antec 110, or for example building on Fractal Design Define R5 and i want to place the ssd and mechanical on the back of the motherboard, i would chose the M9T.
About the speed, the 3.5 should have better sequential, but both are low rpm drives, their latencies are very slow, but the 2.5 should be even worst, i dont recommend them for OS/Games/Programs/Apps, for me this type of drives are mainly for pure storage of videos, movies, pictures, music, etc. I would recommend you consider upgrading your ssd if in fact your will be above 500gb ssd in terms of programs/aps/os/games.
