Is it a good idea thin provision System Drive ?

[TonyJK]

Just wonder whether it is a good idea to thin provision MS 2012 System Disk (C Drive) ?

One argument is the system drive doesn't  change frequently.  On the other hand, another argument is thin provisioning may impact system performance, especailly system drive.

Your advice is sought.

In my opinion it would depend upon the use case of the server.

In case the server is used as a application server and files related to application are again stored on the System Disk which is by default then you should go with thick provisioning.

On the other hand if it going to end up as Database/file server where actual work files are stored on a separate drive then you can provision your system disk as thin.

Hi

In my experience, I haven't seen any problems on thin-provisioned system drive( on Windows Server 2008 R2), however, as previously Donnie pointed, it depends on your application that you intend to run at that virtual server.

It's general advice to use thin-provisioned virtual disk but, to monitor the usage of thin-provisioned disk is more important than to care about its performance.

Hope it works for you.

Best,
