Released on Dell's website on June 26, 2007, the Inspiron 1720/1721 was a 17" large-screen laptop that weighed 7.62 lb and was based on the Intel Santa Rosa platform. The Inspiron 1720/1721 had support for two hard drives and included a full numeric keypad. The Inspiron 1721 had a RAID 0 and RAID 1 options, which was oddly missing from the 1720.
