The Other World Computing External Mini-SAS to Mini-SAS cable attaches to any external storage device that has a Mini-SAS connector.
Mini-SAS is like traffic moving on 4 lanes on the highway instead of just 1 lane. Mini-SAS offers more "lanes" for data to travel, providing the ability to reach higher speeds. Just like the SATA/eSATA interface, mini-SAS offers the convenience of a one cable connection. However, in a multi-drive SATA/eSATA solution which, only offers one lane for four drives to send/receive data on, mini-SAS provides four separate lanes so each drive can deliver its maximum capable data transfer rate. Now you can use one or more mini-SAS equipped external storage enclosures like the OWC Mercury Rack Pro
for greater speed, protection, or both compared to single channel multi-drive eSATA RAID or eSATA Port Multiplier solutions.
