Synology DS220+ vs DS224+ for everyday home use
A two-bay NAS can serve as a private cloud, backup destination, media library, and shared storage hub without taking over an entire room. Synology’s DS220+ and DS224+ are aimed at this space, offering compact hardware, two drive bays, and the approachable DiskStation Manager operating system.
The DS220+ is an older but capable Plus-series model, while the DS224+ is its newer successor. Both use two-core Intel processors, support hardware transcoding, and provide the features most households need for documents, photos, computer backups, and remote access. Their differences are less dramatic than the model numbers might suggest, so the best choice depends on price, connectivity, and expected workload.
For many families, either NAS will feel substantially faster and more flexible than a USB hard drive. The important decision is whether the newer model’s improvements justify buying current hardware, or whether discounted DS220+ stock delivers better value.
Hardware and platform differences
The DS220+ uses an Intel Celeron J boxes? No, J4025, a dual-core processor running at up to 2.9 GHz. It includes 2 GB of DDR4 memory, expandable to 6 GB, and has two Gigabit Ethernet ports. Those ports support link aggregation or failover, although a faster internet connection alone will not make file transfers exceed a single gigabit link.
The DS224+ moves to an Intel Celeron J requirements? J series: J4125, also a quad-core processor? Actually DS224+ specs: Intel Celeron J4125, 4-core, 2.0 burst 2.7GHz. 2 GB DDR4 non-ECC, expandable 6 GB. Two 1GbE. Need accurate. DS220+ J4025 dual core. DS224+ J4125 quad core. Both 2 bays, 3.5/2.5 SATA, Btrfs/EXT4, 2 USB 3.2 Gen 1. DS224+ no eSATA. DS220+ eSATA? DS220+ has 2 USB 3.2 Gen 1 and eSATA? Specs likely 2 x USB 3.2 Gen 1, eSATA? DS220+ rear: 2x 1GbE, 2 USB 3.2 Gen 1. No eSATA likely.
The DS224+ upgrades to Intel Celeron J4125 quad-core, with the same 2 GB starting memory and 6 GB maximum. It also has two Gigabit Ethernet ports and two USB 3.2 Gen 1 ports. Physical storage capacity remains similar, but the extra CPU cores help when several services run together.
Neither system has built-in 2.5GbE or NVMe slots. That limits peak network performance with modern multi-gigabit switches. For ordinary home networks, however, Gigabit Ethernet remains sufficient for backups, document access, streaming, and photo management.
File sharing and everyday speed
With one hard drive or a mirrored pair, both NAS devices can deliver fast sequential transfers near the practical limits of Gigabit Ethernet. The DS224+ may respond better when multiple users browse files, index photos, run containers, or synchronize folders at the same time. The difference is most visible under mixed workloads rather than during a single large file copy.
Synology’s DSM software contributes more to daily usability than the processor specification alone. Shared folders, user permissions, snapshots, Drive file synchronization, and Hyper Backup are managed through a consistent web interface. A household can create separate accounts, protect private folders, and access selected files from phones or laptops without exposing the entire device.
Memory expansion is worthwhile if the NAS will host several applications. Adding a compatible 4 GB module can improve headroom for indexing, Docker-style workloads where supported, and multiple concurrent services. Neither model should be treated as a general-purpose desktop or virtualization server, but both are well suited to light home server tasks.
Storage protection and drive choices
Two bays provide two practical layouts. RAID 1 or Synology Hybrid RAID with two disks mirrors data, allowing the NAS to continue operating after one drive fails. Usable capacity is approximately the size of the smaller disk. A two-disk SHR volume is a sensible default for valuable photos and documents because it is easy to expand later with larger drives.
JBOD or RAID 0 increases usable capacity, but neither provides protection against drive failure. RAID is also not a backup: accidental deletion, ransomware, theft, and electrical damage can affect the whole NAS. A separate USB disk, another NAS, or a reputable cloud destination should hold an additional copy of important data.
Both units can use NAS-rated SATA hard drives or SATA SSDs. Hard disks generally offer the best cost per terabyte for media collections, while SSDs make application loading and random access quieter and more responsive. SSD caching deserves a workload-based decision; this SSD caching guide explains why it can be unnecessary for simple home file storage.

Backups, photos, and media streaming
For family backups, the two models support Synology’s central applications well. Synology Drive can synchronize desktop folders and provide version history, while Hyper Backup can copy selected data to external storage or another destination. Active Backup tools may also be useful for backing up compatible computers, though application requirements and licensing should be checked before deployment.
Photo organization is another strong use case. Synology Photos can automatically upload phone images, organize them by date and album, and provide separate personal and shared spaces. The DS224+’s quad-core processor gives it more breathing room during photo indexing and simultaneous mobile uploads, especially in a busy household.
Both devices can act as media servers, but transcoding expectations matter. Direct playback of compatible video files should be straightforward, while unsupported formats may require conversion. The DS220+ and DS224+ are better suited to a few household streams than to a large media service with many simultaneous 4K transcodes. Keeping client devices compatible with the stored formats reduces CPU demand.
Noise, energy use, and long-term ownership
A two-bay NAS with mechanical disks produces more noise than a silent solid-state appliance, mainly from drive vibration and seeking. Placing it on a stable surface away from bedrooms can make a meaningful difference. SSDs reduce mechanical noise, although they cost more per terabyte and still require sensible backup planning.
Power consumption is modest compared with a desktop computer, but the drives remain the largest variable. DSM supports scheduled power-off, hibernation, and wake-on-LAN features where the network environment permits them. Frequent sleep and wake cycles are not automatically better for every drive, so a predictable schedule is preferable to aggressive idle settings.
The DS224+ is the safer long-term purchase when prices are close. It is newer, has a stronger processor, and is more likely to remain available with current accessories and warranty coverage. A DS220+ can still be a sound choice when sold at a substantial discount, especially for file sharing, backups, and direct-play media.
Choosing the right model for your home
The newer NAS does not change the two-bay capacity limit or add multi-gigabit networking. Users hoping to saturate 2.5GbE, install NVMe cache drives internally, or run demanding virtual machines will need to consider a higher-tier Synology or another NAS platform. The DS224+ is an evolution, not a complete redesign.
Use these recommendations when comparing actual prices and your expected workload:
- Choose the DS220+ if it is significantly cheaper and your priority is basic file storage, backups, and light media serving.
- Choose the DS224+ for photo indexing, several simultaneous users, or a longer expected service life.
- Install two matching or closely matched NAS hard drives and use SHR or RAID 1 for drive-failure protection.
- Budget for a separate backup target instead of spending the entire storage budget on larger internal disks.
- Skip SSD caching unless applications produce frequent random I/O that hard drives cannot handle comfortably.
For most new buyers, the DS224+ is the more balanced everyday home NAS. Its four-core processor offers useful headroom without increasing the basic setup complexity, and it should remain a practical foundation for personal cloud storage, computer backups, and family media for years.
The DS220+ remains attractive as a bargain, refurbished unit, or upgrade from an entry-level NAS. Provided its condition is good and the savings are meaningful, it can provide nearly the same DSM experience and network file-transfer performance. Select the model that leaves room in the budget for reliable drives and a real second backup, then configure it around the data your household cannot afford to lose.
