eSATA is the newest connectivity standard for external enclosures.
eSATA II can operate at 3Gbps which is as fast as a conventional internal
hard drive. APIOTEK's DUAL eSATA II express card not only features dual
eSATA slots for 2 x external enclosures, it also incorporates a RAID
controller giving you the option of having a redundant RAID array as
well.
