64bit 4 Bay NAS + iSCSI with Intel ATOM Dual Core CPU (Black)


The AccuNAS AN4L+ is a performance tuned Network Attached Storage for high capacity network based data storage. Much more advanced than most 4-bay NAS towers on the market, the AN4L+ utilizes the power of Intel ATOM Dual-Core D510 1.66Ghz CPU and 1GB of DDR II memory, to provide exceptionally fast performance. With increased CPU processing power, the AN4L+ is capable of providing enterprise-level features such as iSCSI initiator and target support, snapshot with scheduling, and real-time NAS-to-NAS folder replication. Along with built-in RAID 5 and 6, the AN4L+ provides enterprise-class features that are normally not included in product of such price range.
