Synology's new DiskStation DS1515+ is a 5-bay NAS that houses up to 30TB of raw storage, a quad-core 2.4GHz CPU, and up to 6GB RAM (with upgrade). It was designed for demanding use-cases and serves reported transfer speeds of 450MB/s and 396.5MB/s (read and write, respectively). Like many of Synology's offerings, it also prioritizes security, providing AES-NI encryption with very little decrease in read speeds, in addition to a suite of other features. Each DS1515+ server is scalable up to 90TB (with two Synology DX513 expansion units), and multiple DiskStation servers can be consolidated through Synology's Central Management System (CMS) for enhanced administrative efficiency. Account integration is easily done thanks to support for Windows AD, LDAP, and Domain Trust.

In addition to CMS, multi-server enterprises can make use of Synology High Availability (SHA). SHA clusters passive and active DiskStation servers with "Heartbeat" detection that identifies malfunctioning active servers and transfers their activities to passive servers while the issue is resolved. Synology also loaded the DS1515+ with quad LAN ports (improved link aggregation and improved uptime during port failure), hot-swappable drives (continuous uptime during drive replacement or repair), and a passive cooling contingency in the event of a fan malfunction. All of these features are included to ensure that businesses that rely on the D1S515+ will be protected in the event of almost any type of hardware malfunction. Non-hardware security is maintained through AES-NI encryption, support for Windows ACL (individual file or folder accessibility), Windows Backup, Apple Time Machine, rsync, third-party cloud backup solutions, Synology's Backup & Replication (backup scheduling), Cloud Station (automatic PC file backup), Storage Manager (deployment optimization), and Synology Hybrid RAID (redundant data protection). DS cloud (mobile app) keeps track of file changes with automatic synchronization.

Like all DiskStations, the DS1515+ makes use of Synology's renowned DiskStation Manager (DSM), a sleek browser-based interface with easy administration and access to Synology's Pack Center (add-on packages with business and entertainment applications). User Home lets administrators add "home" folders for all users, and virtualization is supported through VMware (vSphere 5 and VAII integration), Citrix, and Microsoft Hyper-V. The DS1515+ can function as a multi-functioning server with web hosting (Web Server), surveillance (Surveillance Station), email domain creation (Mail Station), printing (Printer Server), and VPN serving. Making use of all of these features reduces the amount of hardware needed for standard business processes.

The DS1515+ carries a price tag of around $800 and has Synology's standard 3-year warranty.

Design and Build

The DS1515+ is more or less identical to the DS1815+ (except that it has three-fewer bays). It has a plastic matte-black chassis with the five drive bays open to the face, each of which is accompanied by a corresponding LED. Above the bays is the power button (in the center), status LED, alert LED, four LAN LEDs, and some branding. The sides feature branding as well. The back opens to two large fans, has an AC adaptor, two eSATA ports (along the base), four USB 3.0 ports (along the right side), and four LAN ports (below the USB ports).
