The EJ1600 expansion enclosure is designed for expanding the storage space on a QNAP Enterprise ZFS NAS by connecting multiple expansion enclosures via high-speed mini SAS cables. Featuring SAS interface on the chassis, the EJ1600 ensures fast data passthrough from SAS-enabled Enterprise ZFS NAS even when using SATA hard drives. This is especially useful for virtualization applications and large data applications that require high-performance interconnection, such as video surveillance, archiving large data, and TV broadcast storage, to provide businesses with optimized efficiency and maximized ROI.
