Does it makes sense to install SQL Server 2017 on one single SSD drive on m5.xlarge with tempdbs, databases, program files, backups and logs for best performance? According to Amazon EBS specs the bigger SSD drive the better IOPS values. https://aws.amazon.com/ebs/features/
It seems if we have 10 300gb disks we get 900 IOPS for those disks, if we have one 3000gb disk we get 9000 IOPS in AWS.
Every article I read recommend to use separate disk partitions https://d1.awsstatic.com/whitepapers/best-practices-for-deploying-microsoft-sql-server-on-aws.pdf So what would be the best approach here?
