Oh this just been a nightmare....and about to shoot my toes.
I upgraded my system wanting to build a raid 5 with 5 8tb hdd Seagate Barracuda ST8000DM004 using the onboard IRST ports.
After almost 2 weeks of initializing which completed, I decided to move all my files from smaller drives into the raid and it started off fine around 150-160 mb/s then after a minute drops down to 7-15 mb/s.
I'm just about to bash my head in for this terrible speeds. I'm not sure if I'm doing something wrong or what, but this is so upsetting.
My system is:
i7 7800x Asus ROG STRIX x299 e-gaming 2x GTX 980 TI SLI Samsung EVO 960 500GB m.2 M.2_1 port
The whole system is in a custom liquid loop. Any help or questions appreciate it.
