Express Flash drives use PCIe and SSD technologies to provide performance, scalability, and optimal
serviceability. Accelerated performance with high IOPs is made possible without requiring processor
resources or capturing DRAM. Also, Express Flash drives use a standardized, 2.5-inch hot-plug form
factor, which saves critical PCIe slot space by moving drives from the back to the front of the system
and allows a common management process for all drives.
The PowerEdge R720 has an option to support up to four hot-plug Express Flash PCIe SSD drives
(available Q2 2012) in the 2.5-inch chassis.
The R720xd does not support Express Flash drives.
