This is not correct. NT will always save historical data loaded to your hard drive, and even one step further, it will cache bars constructed (100 tick for example) from the historical data. NT will (by default) always load the current day from the source to ensure you have complete data.
What this option does is enable writing real-time data to your hard disk. This is a good option if you are using a feed (Patsystems) that does not support historical data. If your data feed does have historical data then its likely uncessary.
