Thecus Y.E.S. Box N2050 RAID External Hard Drive Enclosure
 

The external drive market has always introduced new technologies and expanded its capabilities as the popularity for external drives increases. Originally introduced in late 2005, the External SATA (eSATA) interface boasts 6x better speeds than USB and FireWire. Various external drive manufacturers have started manufacturing eSATA drives and one of the latest offerings from Thecus, the N2050, features not only eSATA but USB 2.0 as well and the ability to install 2 drives in either RAID 0 or 1 configuration
