I just built my first home server and I'm in the process of setting up unraid. I installed my drives, precleared, assigned, formatted, and I'm now doing a Parity-Sync. I'm using Seagate ST12000NM0127 Exos 12TB 7200RPM SATA 6Gb/s 256MB LFF Drives and getting speeds under 20 MB/sec. Running Fix Common Problems reported "Write Cache is disabled" on all my drives and I was able to enable them but didn't see any speed increase. Is there anything else I can do to increase my speed?
