1.  Do you have the commands/steps necessary to format both disks (D: for datafiles and E: for logfiles)?  I want to make sure its done right before proceeding.  This would greatly be appreciated. 

2. One volume has 1.1TB for datafiles, and the logfiles volume has 585Gbs.  So I take it you're saying the alignment for volumes on a Windows 2016 Server are fine then. 

3. I figure having two separate RAID10s for the datafiles and logfiles, and then a RAID5 for the tempdb ought to segregate everything for optimal performance.  The RAID5 array are SSD drives.
