With comprehensive storage options, the Dell PowerEdge R620 offers a choice of drive types,
internal and external storage controllers, and different chassis and backplane options for a varied
numbers of drives.

Features such as Express Flash PCIe solid-state drives and CacheCade provide accelerated
performance over previous technologies. Express Flash drives use PCIe lanes to connect directly to
the processor and chipset, and are easily accessible through the hot-plug drive bay. CacheCade
uses Dell PERC storage controllers to accelerate performance over hard drives or traditional
solid-state drives (SSDs).

With the 8-drive bay or 10-drive bay chassis options, the R620 supports four different internal
storage options:

 4 x 2.5-inch drives
 4 x 2.5-inch drives plus 2 x 2.5-inch Express Flash PCIe SSDs
