Um, NO! not good...
C:\ - OS only
E:\ - Apps - install of sql, various third party if any, ever
M:\ Mdf files - Data files
L:\ ldf files - only logs
T:\ tempdb - only temp
S:\ system databases - msdb, model, master
I know there can be different types of san, disk, mount points, but it is always good to have structure and best practice. 😀
