When Do You Start Worrying About Disk Writing Speed Capacity And RAID Controllers?

Our clients do not require RAID, etc so we use PC's with normal HDD setups for our VMS.

My concern is at what point do we start to worry about the ability to write to the hard drive?

I was told or lead to believe at around 25 cameras, you need a RAID controller to maintain data writing speeds.
