Join Martin Guidry for an in-depth discussion in this video Understanding files and filegroups, part of SQL Server 2012: Designing Database Solutions.
- In this section, we're going to talk about…data files in SQL Server 2012.…There are three types of files available to us.…The first is a Transaction Log file.…Then we have Primary Data files.…And Secondary Data files.…And we'll talk about each of these individually.…The Transaction Log holds a record…of all transactions in the system,…so any time data is changed in any way…information is written to the transaction log…to keep track of those changes.…
Transaction log files always have an LDF extension.…Best practices say we should not…put the transaction log on the same drive as our data files.…We can typically see a fairly significant…performance increase by separating…data files from transaction log files.…There are many activities in SQL Server…that will cause both the data file…and the transaction log files to be written to,…if all of these files are on the same drive,…then we'll have a bottleneck there.…
But if the files are on different drives,…the server can typically write to both files…at the same time, giving a performance increase.…
