Hard Disk Write Cache

By default, the hard disk write cache is disabled. This presetting may be
changed. Consequently, not every data modification in main memory is written
to disk immediately, thus boosting system performance during write operations.

CAUTION!
When a power failure occurs with enabled write cache, data may be lost!
I
The hard disk write cache can only be configured in the same way for all
SATA disk drives at once.
