settings. Adaptec maxCache uses the compatible Solid State Drives (SSDs) in your system as fast cache

memory to improve performance for both read and write operations in I/O-intensive applications with

mixed workloads.

1. Select Manage Arrays from the Logical Device Conguration menu.

2. Select the array, then press Ctrl+C.

The Modify Cache Settings window opens.

3. Enable or disable read caching.

4. Press Tab.

5. Enable or disable write caching:

• Select Enable always for “write-back” caching

• Select Enable with Backup Unit if your controller has a zero-maintenance cache protection module
