Whether you’re considering buying one second-hand or upgrading from an older model, this review will help you decide.
What is the Synology DS1515+?
The Synology DS1515+ is a 5-bay NAS (Network Attached Storage) device designed for home users and small businesses. When it was released, it stood out for its powerful hardware, expandable storage, and the intuitive DiskStation Manager (DSM) operating system. It was built to handle everything from file storage and backups to media streaming and virtualization.
Key specs of the DS1515+ include:
- Processor: Intel Atom C2538 quad-core 2.4 GHz
- RAM: 2 GB DDR3 (expandable to 6 GB)
- Drive Bays: 5 (with support for expansion units)
- Max Storage Capacity: 60 TB (with 12 TB drives)
- Ports: 4 x Gigabit LAN, 2 x USB 3.0, 2 x eSATA
Strengths of the DS1515+ in 2025
Even in 2025, the DS1515+ has some standout features that make it a compelling option:
- Expandable Storage: With 5 drive bays and support for expansion units, the DS1515+ offers plenty of room for growth. This makes it a great choice for users who need a lot of storage but don’t want to invest in a brand-new NAS.
- User-Friendly DSM: Synology’s DiskStation Manager (DSM) is still one of the best NAS operating systems out there. It’s intuitive, feature-rich, and regularly updated, even for older models like the DS1515+.
- Reliability: The DS1515+ is built like a tank. Many users report that their units are still running strong after years of heavy use. If you’re looking for a reliable workhorse, this NAS delivers.
- Cost-Effective: In 2025, the DS1515+ is available at a fraction of its original price, especially on the second-hand market. If you’re on a budget, it’s a great way to get a high-quality NAS without breaking the bank.
Limitations of the DS1515+ in 2025
While the DS1515+ has its strengths, it’s not without its limitations. Here’s what you need to consider:
- Aging Hardware: The Intel Atom C2538 processor and 2 GB of RAM were impressive in their day, but they’re showing their age in 2025. If you’re planning to run resource-intensive applications like virtualization or 4K video transcoding, the DS1515+ might struggle.
- Limited Upgrade Options: While you can expand the storage, upgrading the RAM is limited to 6 GB. This might not be enough for advanced users or businesses with demanding workloads.
- No 10GbE Support: The DS1515+ only supports Gigabit Ethernet, which can be a bottleneck if you’re working with large files or multiple users.
- Power Efficiency: Older NAS devices like the DS1515+ tend to be less power-efficient compared to newer models. If energy consumption is a concern, this might not be the best choice.
