Hi @Antony Maxwin ,

Memory pressure can simply become an issue when the system doesn’t have enough RAM of SQL Server cannot allocate enough memory or more commonly poor database and query design. Lack of memory can also be caused by high I/O.

Dealing with performance problems is not an easy task but it all comes down to I/O, CPU, memory, or concurrency related stuff. Did you meet a SQL performance issue? If so, please using Performance monitor to monitor SQL server performance.

By the way, suggest you put SQL data files and log files to two different drivers when you have two drivers. Placing both data AND log files on the same device can cause contention for that device, resulting in poor performance. Placing the files on separate drives allows the I/O activity to occur at the same time for both the data and log files.
