The Nimbustor 4 utilizes the Intel Gemini Lake Celeron J4105 Quad Core CPU and is 30% faster than Apollo lake. The Celeron J4105 also doubles the on-chip cache to 4MB, making the Nimbustor 4 one of fastest NAS devices ever. The Nimbustor 4 comes with four Gigabytes of DDR4 RAM and can be upgraded up to 8GB. DDR4 RAM provides up to 30% greater performance than DDR3 while also lowering energy requirements by 40%. Enable up to 150% faster performance than Gigabit Ethernet with compatible hardware and up to 5 Gbps using Link Aggregation. The AS53 series devices produce only 19 decibels of noise during system standby, equivalent to the almost inaudible sound of a pin drop. During system operation, only 32 decibels of noise is produced, equivalent to the hushed tones of a quiet library, allowing the AS53 series devices to seamlessly and comfortably integrate into any living environment.
