Select write cache properties
The Escalade Storage Switch gives you a choice of disabling the
write cache for your disk arrays. Write cache is used to store data
locally on the drive before it is written to the disk, allowing the
computer to continue with its next task. Enabling the write cache
results in the most efficient access times for your computer system.
