A hash is an unsorted collection of key value pairs.Within a hash a key is a unique string that references a particular value. Because a hash is unsorted, if it’s contents are required in a particular order then they must be sorted on output.Current Drobo devices can house up to four, five, eight, or twelve 3.5" or 2.5" Serial ATA or Serial Attached SCSI hard disk drives and connect with a computer or network via USB 2.0, USB 3.0, Fire Wire 800, e SATA, Gigabit Ethernet or Thunderbolt. in June 2013, with the new company taking the Connected Data name.Drobo devices are primarily designed to allow installation and removal of hard disk drives without requiring manual data migration, and also for increasing storage capacity of the unit without downtime. changed its name from Data Robotics in 2011 since the familiarity with the Drobo name (which until then had only been the name of their product line) far exceeded the Data Robotics name.
