mode
—Select a cache mode. Options are:
{
Disabled
(write through)
—New data is written to the cache and the physical drive at the
same time. Writing data will experience latency as the data need to be written to two places.
{
Enabled (write back)
—New data is written only to the cache. The data is written to the
physical drive only when it needs to be replaced and removed from the cache. This mode
boasts low latency but entails data loss risks because a power failure might prevent the data
from being written to the physical drive.
