The Synology DS1522+ represents a strategic investment for those who are serious about their data. It’s not just about throwing drives into a box.
It’s about building a reliable, scalable, and feature-rich private cloud that keeps your digital assets secure and accessible.
Performance and Processing Power
The Synology DS1522+ packs a punch with its AMD Ryzen V1500B quad-core processor clocked at 2.2 GHz. This isn’t just some off-the-shelf CPU. it’s an embedded chip designed for workloads like those a NAS handles. Paired with 8GB of DDR4 ECC RAM, expandable up to 32GB, this unit is engineered for stability and performance. ECC Error-Correcting Code RAM is a crucial detail often overlooked by those new to NAS. It detects and corrects memory errors, which is vital for data integrity, especially in a server environment where data corruption can have disastrous consequences. Think of it as a quality control checkpoint for every bit of data moving through your system – it minimizes the chance of silent data corruption, which is something you definitely want to avoid when dealing with your precious files.
CPU Performance in Real-World Scenarios
The Ryzen V1500B, with its four cores and eight threads, provides ample horsepower for a variety of demanding tasks. For instance, in our testing, it handles multiple concurrent users accessing files without breaking a sweat. When it comes to file transfers, you can expect consistent speeds, especially when leveraging the optional 10GbE upgrade. For example, large file transfers think ISOs or video project files can easily saturate a 1GbE connection, but with 10GbE, you’re looking at transfers upwards of 800-900 MB/s, which is a must for professional workflows. This translates to significantly reduced waiting times for moving multi-gigabyte datasets.
RAM and Expandability
The standard 8GB of ECC RAM is sufficient for most home users and small offices running basic file services, backups, and a few Docker containers. However, the ability to expand up to 32GB is where the DS1522+ truly shines for more advanced users. If you plan on running multiple virtual machines Synology Virtual Machine Manager, hosting web servers, or deploying a large number of Docker containers, upgrading the RAM is highly recommended. More RAM means the system can cache more data, allowing for faster access times and smoother operation of multiple services simultaneously. For example, if you’re running a Plex server with multiple simultaneous 4K transcodes, or a Surveillance Station instance with dozens of cameras, that extra RAM capacity becomes critical to maintain responsiveness.
Storage and Scalability
The DS1522+ is inherently a 5-bay NAS, which offers a substantial starting point for storage capacity. With current hard drive capacities, you could easily fit over 100TB of raw storage, allowing for massive archives of photos, videos, and business documents. But what truly sets it apart is its expandability. Synology understands that data needs grow, and rather than forcing you into a new unit, they provide a seamless upgrade path.

Drive Bay Configuration and RAID Options
With five drive bays, you have a plethora of RAID configurations at your disposal. Synology’s proprietary Synology Hybrid RAID SHR is often the go-to for most users. SHR offers flexibility by allowing you to mix and match drive sizes, while still providing data redundancy. For example, if you start with three 4TB drives in SHR, you get 8TB usable space with one drive redundancy. Later, if you add an 8TB drive, SHR will automatically optimize storage to provide more usable space while maintaining redundancy. This is a significant advantage over traditional RAID levels like RAID 5 or RAID 6, which require drives of the same size for optimal space utilization. Beyond SHR, you can, of course, configure traditional RAID 0, 1, 5, 6, 10, or JBOD, catering to specific performance or redundancy requirements.
NVMe SSD Cache and Its Impact
One of the most impactful features is the inclusion of two M.2 NVMe SSD slots beneath the main drive bays. These slots are dedicated for SSD cache, not for direct storage volumes. SSD caching significantly improves performance for frequently accessed data, particularly for random read/write operations. Imagine a scenario where multiple users are accessing small, fragmented files, or a database server running on the NAS. The NVMe cache accelerates these operations by storing frequently accessed data on the much faster SSDs, reducing latency and improving overall system responsiveness. For example, a benchmark might show a 2x to 5x improvement in random read IOPS with a properly configured NVMe cache. It’s like giving your NAS a turbo boost for its most common tasks, making everything feel snappier.
DX517 Expansion Unit Support
For those who exhaust the five internal bays, the DS1522+ supports the Synology DX517 expansion unit. This unit adds an additional five drive bays, effectively transforming your DS1522+ into a 10-bay system. The connection is via a single eSATA cable, which is important to note. while convenient, it’s not as fast as an internal SATA bus, but it’s perfectly adequate for expanding storage volumes. This provides a cost-effective and convenient way to scale your storage without migrating your entire system to a larger NAS unit. It means your initial investment in the DS1522+ can last much longer, accommodating growing data needs over years.
Connectivity and Networking
Connectivity is crucial for any NAS, and the DS1522+ offers a solid foundation with impressive upgrade potential. While it comes with four 1GbE LAN ports, the true differentiator is the PCIe 3.0 x2 slot that allows for a 10GbE network upgrade.
Multi-Gigabit Networking with 10GbE
The inclusion of a PCIe slot for a 10GbE upgrade card like Synology’s E10G22-T1-MINI is a significant selling point. For power users, content creators, and small businesses dealing with large files, 1GbE can quickly become a bottleneck. Upgrading to 10GbE means your network can now push data at up to 1250 MB/s, assuming your drives and CPU can keep up. This is particularly beneficial for:
- Video editing workflows: Direct editing of high-resolution video files stored on the NAS without transferring them locally.
- Large file transfers: Moving multi-terabyte datasets across your network in minutes, not hours.
- Virtual machine performance: Reducing I/O latency for VMs running on the NAS.
- High-speed backups: Backing up critical data at significantly faster rates.
It’s a must if you have other 10GbE devices on your network, like workstations or high-end switches.
Without a 10GbE switch, you won’t realize these speeds.
A simple TP-Link TL-SX1008 8-Port 10G Multi-Gigabit Unmanaged Switch can dramatically improve your network performance.
Link Aggregation and Failover
The four 1GbE ports aren’t just for show. They support Link Aggregation LAG, also known as LACP Link Aggregation Control Protocol. This allows you to combine the bandwidth of multiple 1GbE ports to increase throughput or provide network redundancy failover. For example, with two 1GbE ports aggregated, you could theoretically achieve up to 2Gbps of throughput with multiple concurrent connections, or have one port act as a backup if the other fails. This ensures higher availability and faster data access in scenarios with multiple users or services. While it doesn’t give a single client 4Gbps, it enhances the overall network capacity for the NAS.
USB 3.2 Gen 1 Ports
The DS1522+ features three USB 3.2 Gen 1 ports one on the front, two on the rear. These are incredibly useful for various tasks, including: Nikon Z Fc Review
