Is it desirable to set "memcached" for "Page Cache" in W3 Total Cache?

I set "memcached" for the option "Page Cache" in the W3 Total Cache plugin in WordPress.

I read some posts which suggested to set "Disk: Enhanced" for "Page Cache."

In this case, is it desirable to set "memcached" for "Page Cache" in W3 Total Cache? (For your reference: the memcached size has been set to 512 MB.)

Thanks.
