This synology 2 bay quad core NAS 24tb review focuses on the Synology DS225+ with 24TB of included storage. It is a compact network-attached storage device designed for home and small office use. The unit features an Intel Celeron J4125 quad-core processor and 2 GB of non-ECC DDR4 SODIMM RAM. These two specifications define its performance ceiling and multitasking capability. You get a pre-configured 2-bay enclosure that simplifies initial setup. The system runs Synology’s DSM operating system, which manages your data efficiently. This guide breaks down how these specs translate to real-world reliability and speed for your files.
What stands out
- Intel Celeron J4125 Quad-Core processor for steady performance.
- 24TB of pre-installed storage in a compact 2-bay chassis.
- 2 GB DDR4 non-ECC RAM, expandable to 6 GB.
- Support for Synology Hybrid RAID (SHR) for flexible drive management.
Who it fits
Good fit for
This NAS suits users who need a large amount of storage without managing individual drives. The 24TB capacity is ideal for media libraries or extensive document backups. The quad-core processor handles multiple tasks smoothly, making it good for small teams. If you want a simple setup with Synology’s user-friendly interface, this model fits well. The expandable RAM allows you to add features like Docker or virtual machines later. It is a practical choice for those prioritizing data safety and ease of use over raw speed.
Who should skip it
You should look elsewhere if you require high-speed network transfers. This model includes a 2.5 GbE port, which is slower than the 5GbE or 10GbE options found in higher-end units. If you plan to run many simultaneous Docker containers or heavy virtual machines, the base 2 GB RAM may limit your options. You might need to upgrade the memory immediately. Also, if you prefer a drive-less barebones system, this pre-loaded 24TB version is not the right fit. Stick to models with more network ports for heavy enterprise workloads.
Verdict: The Synology DS225+ with 24TB offers a balanced mix of storage capacity and processing power for home users. It is a reliable choice for those who value simplicity and data protection features.
Key specs explained for you
Processor: Intel Celeron J4125 Quad-Core
This four-core chip handles multiple tasks without slowing down. You can run file syncing, virtual machines, and media transcoding at the same time. It offers more power than dual-core models found in entry-level NAS drives. This makes it suitable for users who need responsive performance for several apps running simultaneously.
RAM Capacity: 2 GB DDR4 non-ECC SODIMM
The system comes with 2 GB of memory to manage active processes. It supports expansion up to 6 GB by adding a 4 GB module. More RAM allows the NAS to cache more data and run heavier applications smoothly. If you plan to use many services, upgrading the memory is a practical step for better stability.
Included Storage: 24TB
This unit includes 24 terabytes of pre-installed hard drive space. You get immediate capacity for photos, documents, and media libraries without buying separate drives. This total volume suits users who need large centralized storage. It reduces initial setup time and ensures compatibility between the drives and the NAS enclosure from day one.
RAID Support: Synology Hybrid RAID (SHR)
SHR allows flexible storage management across different drive sizes. You can mix and match hard drives while maintaining data redundancy. This feature protects your files if one drive fails. It simplifies storage planning compared to standard RAID levels, as it adapts to your current and future drive configurations without requiring identical sizes.
Network Connectivity: 5GbE, 1GbE
The device includes a 2.5 Gigabit Ethernet port for faster local transfers. This speed exceeds standard 1 Gigabit connections, reducing time for large file backups and media streaming. It ensures your network does not become a bottleneck. You benefit from quicker access to files within your home or office network compared to older single-gigabit models.
Design and build details
According to the listing, the Synology DS225+ measures 4.72 inches in height. The total weight is 4.41 pounds. The chassis is finished in black. These dimensions make it a compact unit for a desk or shelf. It fits easily into tight spaces without taking up much room. The low profile suits home offices or small workspaces where space is limited.
The device features two drive bays for your storage media. You can install up to two hard drives inside. The front panel likely houses status indicators and drive activity lights. The back includes the network ports and power connector. This layout keeps cables organized and accessible. You can plug in the Ethernet cable and power supply without bending over. The design prioritizes straightforward connectivity for daily use.
The build quality appears solid for its class. The plastic enclosure protects the internal components from dust and minor impacts. It is not designed for harsh environments. You should place it in a clean, indoor area. The compact size means it does not require a dedicated rack. You can simply set it on a flat surface. The design supports quiet operation for residential use. It blends into a home office setup without drawing attention.
Setup and everyday use
Setting up the Synology DS225+ begins with installing the included 24TB drives into the two-bay chassis. You connect the network cables to the available ports. The listing notes 5GbE and 1GbE connectivity options. This allows you to choose the speed that matches your current router. The device runs Synology’s DiskStation Manager operating system. You access this interface through a web browser on your computer or mobile device.
The system supports Synology Hybrid RAID. This feature lets you mix drive sizes for flexible storage management. You can balance capacity and redundancy based on your needs. The NAS uses the Btrfs file system. This provides advanced data protection. You can create snapshots to protect your files from accidental deletion or corruption.
A notable update is compatibility with third-party drives. Since DSM version 7.3, you are not locked into specific brands. This gives you more freedom when replacing drives in the future. The unit comes with 2 GB of DDR4 non-ECC SODIMM memory. You can expand this to 6 GB by adding a 4 GB stick. This extra RAM helps when running multiple services simultaneously.
Daily use involves managing files through the web interface. You can set up shared folders and user permissions. The quad-core processor handles file syncing and media transcoding tasks. It supports virtual machines if you have the memory. The compact design keeps it quiet and unobtrusive on your desk.
Check Network And Memory Needs
Before you buy this Synology DS225+ with 24TB, consider your network infrastructure. The listing highlights 5GbE and 1GbE ports. You need a compatible router or switch to utilize the higher speed. If your current setup only supports 1GbE, you will not see the full benefit of the 5GbE port. Also, check your existing third-party drives. The product data states it is now compatible with third-party drives since DSM 7.3. This flexibility allows you to mix brands if needed, but verify your specific drive models. Memory expansion is another factor. The unit comes with 2 GB of DDR4 non-ECC SODIMM memory. You can expand it up to 6 GB by adding a 4 GB stick. This upgrade helps if you plan to run multiple virtual machines or heavy container workloads. Finally, ensure you have the necessary SATA cables and power supplies if you are building a larger array alongside this 2-bay unit.
Check before you buy
- Verify your router supports 5GbE speeds.
- Confirm third-party drive compatibility with DSM 7.3.
- Plan for potential RAM upgrade to 6 GB.
- Ensure you have enough SATA cables for expansion.
