Hello,
I am purchasing a new SQL server that will have fast SSD SAS 12Gbps drives and I would like to create one RAID10 - 1.6TB partition. MS still recommends separating the data and log files on different disks for SQL 2017, but just wondering if there is still performance improvements by separating data and log files.
What is the best option for performance?
1. One RAID 10 array with one partition?
2. One RAID 10 array with two partitions - one partition includes OS and data and one partition for log files.
3. One RAID 10 array with three partitions - one partition for OS, one partition for data and one partition for log files.
4. Two or three RAID 10 arrays with a partition for each - OS, data and log files.
Thanks!
