In-Depth Reviews: Synology, Buffalo, and UGREEN Small NAS Enclosures
#1. Synology DS220+ Balanced home NAS
Quick Verdict
Best For: Home users and homelabers who need a compact 2-bay small NAS enclosure for mirrored backups and occasional Plex streaming.
- Strongest Point: Dual 1GbE link aggregation delivering over 225 MB/s sequential read and 192 MB/s sequential write per Synology lab figures.
- Main Limitation: Two drive bays limit on-device RAID flexibility because RAID 5 is not possible with two drives.
- Price Assessment: At $386.81, the DS220+ offers more memory expansion and AES-NI encryption hardware than lower-cost alternatives such as the UGREEN DXP2800 at $284.99.
Many home users struggle with slow file transfers and weak encryption while keeping a compact footprint, and the Synology DS220+ addresses that problem by pairing dual 1GbE ports with an Intel dual-core processor and an AES-NI hardware encryption engine. The full Synology DS220+ supports Link Aggregation and Synology states it can deliver over 225 MB/s sequential read and 192 MB/s sequential write in lab tests using dual 1GbE. With 2 GB DDR4 memory expandable to 6 GB, the DS220+ aims to reduce CPU bottlenecks for encrypted transfers and photo indexing workloads of about a 15 performance boost reported for those tasks.
What We Like
What stands out is the DS220+ dual 1GbE link aggregation support with measured throughput of over 225 MB/s sequential read. Based on Synology’s lab numbers for Link Aggregation, that enables faster bulk file copies on gigabit networks compared with single-port designs. I find this valuable for users moving large photo or media libraries across the home network.
The DS220+ includes an Intel dual-core processor with an AES-NI hardware encryption engine and 2 GB DDR4 memory expandable up to 6 GB. With AES-NI present, encrypted SMB/CIFS or NFS transfers offload cryptography to hardware, which reduces CPU load compared to software-only encryption based on the product spec. I recommend this to buyers who plan to enable on-disk encryption or run database-heavy services on a small NAS enclosure.
The DS220+ reports a Noise Level of 19.3 dB(A), which is typical for home-grade small NAS enclosures designed for living spaces. At that noise rating, the DS220+ is quieter than many desktop PCs and suitable to place near a home office or media cabinet according to the spec. I would point photographers and media collectors who need a quiet backup target to this model.
What to Consider
Drive bay count is a real constraint because the DS220+ has two drive bays, so RAID 5 and multi-disk redundancy are not possible on-device. Based on the two drive bay design, buyers who require RAID 5 for larger arrays should choose a four-bay model or a dedicated 4-bay enclosure instead.
Network speed is limited to dual 1GbE ports, which means maximum on-wire throughput is bounded by gigabit infrastructure unless you add additional networking hardware. If you need native multi-gigabit NICs for heavier Plex transcoding or concurrent VM storage, consider alternative enclosures or add a switch that supports link aggregation for best results.
Key Specifications
- Price: $386.81
- Network: Dual 1GbE LAN ports (Link Aggregation supported)
- Performance (Synology): Over 225 MB/s sequential read and 192 MB/s sequential write with Link Aggregation

Many users struggle with scattered files and rising cloud subscription costs; the UGREEN DXP2800 addresses that problem by offering local consolidation with up to 76 TB of stated capacity. The UGREEN DXP2800 provides that capacity for a one-time price of $284.99, which reduces recurring costs compared with cloud storage. Based on the product description, the UGREEN DXP2800 targets enthusiasts and small teams who want a user-friendly on-premises storage platform.
What We Like
The UGREEN DXP2800 lists a maximum storage capacity of 76 TB, which is the clearest strength from the available data. That capacity means you can centralize large photo and video libraries without immediate drive upgrades, based on the stated figure. I see this as valuable for small teams and hobbyist video editors who store multi-terabyte projects.
The UGREEN DXP2800 has a stated price of $284.99, presenting a lower entry cost than some rivals. That lower purchase price lowers the total cost of ownership compared with ongoing cloud fees, based on the product description’s “one-time purchase” claim. I recommend this price-to-storage balance for budget-conscious home users and small offices.
The UGREEN DXP2800 description emphasizes an intuitive and “user-friendly” NAS experience aimed at users moving from cloud drives. That statement suggests the NAS operating system focuses on straightforward setup and file organization, according to the product text. I find this important for buyers who prefer simple migration from cloud folders to local SMB/CIFS or NFS shares.
What to Consider
Critical hardware details such as CPU model, memory size, and network port counts were not provided in the product data, which limits performance evaluation. Performance analysis is limited by available data; based on missing CPU and NIC specs, expect to verify throughput and Plex transcoding capability before assuming high-performance behavior. If you need guaranteed AES-NI encryption or a specific CPU profile, consider the Synology DS220+ where vendor specs are published.
The product information does not list drive bay features like hot-swap support, RAID modes, or SSD cache capability, so drive bay flexibility remains unclear. Because RAID 1 versus RAID 5 behavior and hot-swap bays affect backup and uptime strategies, confirm those items with the seller prior to purchase. For buyers who require explicit RAID 5 support and documented SSD cache options, the Buffalo LinkStation 220 or other documented models may be safer choices.

How to Choose a Small NAS Enclosure for Home and Homelab Use
When I’m choosing a small nas enclosure comparison, I prioritize drive bay count and network throughput because those two specs determine usable capacity and sustained transfer rates. In my experience, balancing drive bay flexibility with CPU encryption support and noise targets separates useful home-grade small NAS enclosures from models that disappoint under multi-user load.
Drive Bay Flexibility
Drive bay flexibility means how many physical drive bays and layout options the unit provides, with typical values in this category ranging from 2 drive bays to 4 drive bays. Buyers will see options that support 2-bay for mirrored setups and 4-bay for RAID 5 or mixed SSD/HDD pools.
Drive bay flexibility suits different buyers by outcome: 2 drive bays are right for single-user RAID 1 backups, 4 drive bays suit photo editors or homelabs needing RAID 5 and expansion, and modular hot-swap cages benefit lab users who replace drives often. If you plan to add SSD cache or mix drive sizes, choose a unit with 4 drive bays or explicit SSD-caching support instead of a fixed 2-bay design.
The price data show how bay choices map to cost: the UGREEN DXP2800 at $284.99 occupies the lower price band where many buyers accept fewer expansion options, while the Synology DS220+ at $386.81 sits in the mid-price band commonly chosen for balanced capacity and features.
Network Connectivity Options
Network connectivity options determine sustained throughput; typical small NAS enclosures in 2026 offer single 1GbE, dual 1GbE with link aggregation, or a single 2.5GbE port. Link aggregation (LAG) across dual 1GbE ports is common and can raise multi-client throughput when your switch supports LAG.
Buyers who need Plex media streaming to multiple devices or multi-user backups should choose units with dual 1GbE and link aggregation or native 2.5GbE; single 1GbE is fine for single-user backups and simple photo libraries. For homelab virtualization or heavy SMB/CIFS traffic, prioritize link aggregation or 2.5GbE to avoid network bottlenecks under concurrent loads.
The Buffalo LinkStation 220 at $329.99 illustrates the mid-to-budget connectivity trade-off where buyers often accept basic 1GbE design to save cost while relying on internal caching to smooth performance.
CPU and Encryption
CPU and encryption capability refers to processor performance and whether the CPU includes AES-NI hardware acceleration, which affects encrypted transfer speeds and on-device compression. Typical small NAS enclosures use low-power ARM or low-end x86 CPUs, and only some include AES-NI for hardware AES acceleration.
Buyers who plan to use on-the-fly encrypted volumes, run VMs, or host containers should prefer a unit with AES-NI and a stronger CPU; casual backup users can accept CPU designs without AES-NI if they don’t encrypt traffic or run VMs. If vendor CPU spec is missing, state that performance analysis is limited by available data and base expectations on listed CPU class and clock speed when provided.
The Synology DS220+ at $386.81 is commonly selected in this category for users who want a balance of CPU capability and ecosystem support without stepping into higher-priced x86 models.
Supported RAID Levels
Supported RAID levels define redundancy and usable capacity; small NAS enclosures usually support RAID 0, RAID 1 on 2-bay models and RAID 5 or JBOD on 3-4 bay models. RAID 1 mirrors two drives, while RAID 5 requires at least three drives to provide parity and better capacity efficiency.
Choose RAID 1 if you want simple mirrored backups for a single-user home backup, choose RAID 5 on 4-bay units when you need a balance of redundancy and capacity for multi-user file sharing, and avoid expecting RAID 5 from a 2 bay NAS because the hardware limitation prevents that configuration. Remember RAID protects against drive failure but not accidental deletion; keep external backups even with RAID configured.
OS and App Ecosystem
The NAS operating system determines available services such as SMB/CIFS, NFS, iSCSI, Docker, and plugin apps; common OSs in this market vary in app availability and update cadence. A mature NAS operating system will provide app-managed Plex, container support, and scheduled snapshots, while simpler OS builds may only offer basic SMB/CIFS file serving.
Choose a unit with a proven NAS operating system if you plan to run Plex media server, Docker containers, or iSCSI targets; lightweight OS choices suit buyers who only need straightforward file backup and SMB/CIFS shares. If the vendor documentation omits app support details, treat containerization and VM hosting as unsupported until verified.
Noise and Power Draw
Noise and power draw determine whether a unit is acceptable in a home office; typical idle noise for small NAS enclosures ranges around low 20s to mid 30s dB(A) and power consumption often falls between 6 W idle and 20-30 W under load. Fans, drive count, and CPU class drive both noise and wattage.
Buyers placing a NAS in a living space should target models advertised with low idle dB(A) and 2-bay designs to reduce fan size and HDD activity, while homelab users tolerating rack or closet placement can accept higher power draw for increased performance. If a product page lacks measured dB(A) or wattage, note that real-world noise and power depend on installed drives and workload and should be tested before placing the unit in quiet areas.
What to Expect at Each Price Point
Budget tier units cost about $250-$320 and typically include basic single or dual 1GbE ports, modest CPUs, and limited app ecosystems; buyers here are budget-conscious home backup users. Examples in this tier include the UGREEN DXP2800 at $284.99.
Mid-range units cost about $320-$420 and commonly offer improved CPUs, dual 1GbE with link aggregation, richer NAS operating systems, and better memory expansion; these suit Plex servers and small homelabs. The Buffalo LinkStation 220 at $329.99 and the Synology DS220+ at $386.81 fall into this band.
Premium tier units start above $420 and add features like 2.5GbE/10GbE, AES-NI-equipped CPUs, and more RAM for VMs and SSD cache; buyers who run multiple VMs, heavy SMB/CIFS workloads, or multi-user media streaming belong here.
Warning Signs When Shopping for small NAS enclosures
Avoid models that list maximum supported capacity without specifying whether that figure is per-bay or total capacity because the two are not comparable. Watch for products that advertise “SSD support” without clarifying SSD cache or dedicated M.2 slots, and avoid units that omit any mention of RAID level support or NAS operating system capabilities because those are critical to backup and sharing functionality.
Maintenance and Longevity
Replace failing drives promptly; check S.M.A.R.T. reports monthly and replace any drive reporting reallocated sectors to avoid RAID rebuild failures during subsequent drive loss. If neglected, degraded RAID arrays risk total data loss during rebuilds.
Update NAS operating system firmware and apps every 3-6 months to keep security patches current and check drive bay screws and fan bearings annually; failing to update firmware increases exposure to vulnerabilities and can reduce long-term reliability.

Buyers should typically expect a manufacturer warranty of 1 to 3 years for small 2 to 4 bay NAS enclosures. Exact terms vary by model and by sales region.
Manufacturer warranty lengths: Manufacturer warranties commonly run 1 to 3 years and vary by model and region. Confirm the exact term for each model and region before purchase.
Drive exclusions: Warranties typically exclude installed HDDs and SSDs, whose warranties come from the drive manufacturer. For replacement or failures, file claims with the drive maker, not the NAS maker.
Commercial use restrictions: Consumer warranties can exclude commercial or high-duty-cycle deployment for NAS enclosures. Check warranty language if you plan business or heavy-write workloads.
Firmware and hardware modifications: Firmware modification, third-party OS installs, or unofficial hardware mods frequently void warranty coverage. Avoid unsupported changes if warranty service matters.
Registration and RMA procedures: Some manufacturers require product registration for expedited RMA or extended coverage. Note registration windows and follow the listed procedures on the manufacturer website.
Cross-border limitations: Warranties and RMA service centers may be region-locked, limiting cross-border support. You may need to ship units to the original purchase country for service.
Data recovery exclusions: Warranties cover hardware replacement but normally exclude data recovery for lost files. Maintain backups and verify third-party recovery options separately. Before purchasing, verify warranty term, registration windows, RMA region limits, and drive warranty responsibilities.
