Easily scalable, the DS2415+ can be equipped with up to 6GB of DDR3 RAM & host up to 144TB of raw capacity with a Synology DX1215 expansion unit. Quad-core CPU for blazing-fast performance DS2415+ is powered by a quad-core CPU running at 2.4 GHz. Combined with 2GB of DDR3 RAM (expandable to 6GB), it delivers blazing-fast performance over 451 MB/s reading & 415 MB/s writing. That much power makes it easy for DS2415+ to multitask & provide consistently high throughput to all connected clients. Fast encrypted data transmission with AES-NI Encrypting data is essential to a healthy security policy. Equipped with a dedicated hardware encryption engine, DS2415+ is the ideal digital locker for sensitive data; files & folders are encrypted on the fly without any perceived performance loss. DS2415+ delivers encrypted data transmission speeds over 450 MB/s reading & 198 MB/s writing. Robust scalability up to 24 drives As your data storage needs grow, DS2415+ can be connected to a dedicated DX1215 expansion unit 2 for additional storage on the fly, growing capacity with minimal effort. With a DX1215 connected through a cable with specially-designed locking connectors, raw capacity can be as high as 144TB3. Quad LAN ports for failover & Link Aggregation support Equipped with four RJ-45 Gigabit Ethernet ports featuring failover & Link Aggregation support, DS2415+ ensures continual network uptime even if LAN connection malfunction occurs on one port, reducing the chance of service disruption & costly downtime. Link Aggregation improves connection speeds beyond the limits of a single network cable or port. SSD cache technology DS2415+ enables the combination of hard drives & read/write-optimized SSD cache, boosting throughput efficiently while minimizing cost per gigabyte. With full SSD cache reading & writing support, DS2415+ offers a significant reduction in I/O latency without crippling your budget. With only a small upfront investment, businesses can benefit from significant server performance enhancement. Easy installation, hassle-free maintenance Easy installation & hot-swappable hard drive support ensures easy maintenance & continuous service uptime should a hard drive need replacement. In addition, DS2415+ incorporates a passive cooling design to reduce dependency on the dedicated processor cooling fan, thus mitigating any critical point of failure. When the system detects a fan failure, the built-in redundancy mechanism ensures continuous operation until the replacement fan arrives. USB (Universal Serial Bus) 3.0 ensures speedy transfers to external storage DS2415+ boasts USB (Universal Serial Bus) 3.0 ports to connect to various kinds of external storage devices, while ensuring fast & efficient file transfer speeds. Support for USB (Universal Serial Bus) 3.0 offers transfer speeds of up to 5 Gbps (about 10 times faster than USB (Universal Serial Bus) 2.0), meaning it takes less time to transfer data to external hard drives, while also consuming less power.
