I am looking to buy HDDs for a single server which will be used as development server. The server will use ESXi as hypervisor and will have some but not too many virtual machines (web server, database server, file server)
We have already taken a Samsung 950 Pro 256 GB for the virtual machines but I struggle in finding an answer to the question:
In a RAID 10: Are lots of slow disks (5400/5900 rpm) faster than fewer fast disks (7200 rpm)? For example 8x 5400rpm vs 4x 7200rpm
Would the 8 slow be a better choice compared to the 4 fast?
My choice was between 1TB WD Red which run at 5400rpm vs 2TB WD Se 7200rpm.
