Edy,
we are also looking at this Equalogic hybrid storage to expend our storage and I would say depending on the number of view machines you have, if you refresh after log off and so on yes it is worth the investment.
I experienced issues like boot storm before going to ssd for our view environment and today with those I can recompose a pool of 100 machines in the middle of the day without impacting users and this is priceless.
