With Dell's latest servers, the 12th time's the charm. The Dell PowerEdge R720 currently holds the CRN Test Center record for fastest general-purpose production file server as measured by Geekbench from Primate Labs. The R720 can accept as many as 16 internal hard drives for a maximum hard drive capacity of 24 TB, one full-length, full-height x16 PCIe slot, plus three x8 slots. Add Dell's four optional hot-plug PCIe SSDs with dual RAID controller capability and the R720 alone is capable of multitiered, front-accessible storage. Dell's PowerEdge R720 is one cool and versatile server.
