  • $959.00

Quad-core CPU for high performance

Powered by a quad-core CPU combined with 2GB of DDR3 RAM, DS1515 delivers outstanding performance over 403.77 MB/s reading and 421.85 MB/s writing with Link Aggregation enabled. Powerful hardware enables DS1515 to deal with considerable amounts of data processing requests and provide consistently high throughput to all connected clients.

Hardware encryption engine and floating-point unit

DS1515 is equipped with a dedicated hardware encryption engine, delivering encrypted data transmission speeds over 296.54 MB/s reading and 150.04 MB/s writing with Link Aggregation enabled. DS1515 also features a built-in floating-point unit which enhances the overall capability of the main CPU to enable higher working efficiency.

Quad LAN ports for failover and Link Aggregation support

Equipped with four Ethernet ports featuring failover and Link Aggregation support, Failover support ensures continual network uptime even if LAN connection malfunction occurs on one port, reducing the chance of service disruption and costly downtime. Link Aggregation improves connection speeds beyond the limits of a single network cable or port.

SSD cache technology

DS1515 enables the combination of hard drives and read/write-optimized SSD cache, boosting throughput efficiently while minimizing cost per gigabyte. With full SSD cache reading and writing support, DS1515 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.

Robust scalability up to 15 drives

As your data storage needs grow, DS1515 can be connected with up to two dedicated DX513 expansion units for additional storage on the fly, growing capacity with minimal effort. With two DX513 connected through cables with specially-designed locking connectors, raw capacity can be as high as 120TB.

Reliable redundancy mechanisms

DS1515 comes with four LAN failover support to ensure continual network service in case of LAN failure, while the hot-swappable design facilitates easy and risk-free hard drive replacement. The hard drive tray lock design further secures your hard drives from unauthorized or accidental withdrawal.

USB 3.0 and eSATA ensure speedy transfers to external storage

DS1515 boasts USB 3.0 and eSATA ports to connect to various kinds of external storage devices, while ensuring fast and efficient file transfer speeds. Support for USB 3.0 offers transfer speeds of up to 5 Gbps (about 10 times faster than USB 2.0), meaning it takes less time to transfer data to external hard drives, while also consuming less power.
