O&O CleverCache - 29
The "Mem-O-Safe" feature in O&O CleverCache reduces the risk of possible data loss in the event of a sys-
tem crash. This reduction in risk is achieved by allowing users to manually set the assessment interval for
the file cache in Windows.
The more you want to transfer data from the cache to the hard disk, the lower you have to set the interval.
The minimum is 50 milliseconds.
Before your data is written to the hard disk, they are first written to the file cache. The rationale behind this
design is efficiency. Because the constant writing of small amounts of data to disk would not be an efficient
use of time, this system was developed to optimize the process and overall performance. For this reason,
Windows saves data to disk in intervals, so that the system can economize on the amount of data saved at
once.
This interval, although defined by Windows, is not set in stone. It is determined according to a number of
factors: the size of the file cache, the system speed, and results of the last write process. Generally, this
interval is anywhere between 4 and 15 seconds.
If a system crash happens to fall between those intervals (e.g. program error, accidental shutdown, or
power outage), data stored in the file cache is lost forever.
Important: If you set the interval value to low (less than a second), you will be instructing the computer
to save data to disk with a very high frequency. On the other hand, should this value be set too high,
system performance will increase. However, along with higher performance, the risk of data loss in the
event of a system crash also increases.
