Apart from the dissimilar quantity of hard drive cove, these two external hard-drive field both support USB 3.0 and eSATA connections. They are intended to host multiple regular size (3.5-inch) SATA hard drives.

According to San Digital, both hard drives have two-port eSATA 6Gbps PCI host bus adapters for systems without eSATA ports. Note that this add-in card compatible with the newest pace of the SATA normal and is as a result faster than that of USB 3.0, which caps at 5Gbps.
