I finally got to the install of the 512GB 850 Pro on my test mule, used the Apples-to-Apples (pun intended…What kind of performance are you seeing on the 850 pro drives?
I opted to leave the stock 2nd 1TB spinner in the Mini even though it's SATA II and instead bought an on-sale 8TB WD easystore for DAS to be attached to my Mini. The easystore unit is on sale this week at Best Buy for $180, and I will likely buy a second - these units have WB Red drives in them and I can't even touch a bare 8TB Red for that little coin. I'll be connecting them to my Synology RT2600ac router as a NAS setup (using Synology's SW solution for this beast of a router!) - burn, backup, and backup the backup.
Cheers! And, have a great weekend!
