Buffalo LinkStation 210 4TB
Score: 56/100
Synology DS223j 2-bay
Score: 70/100Rankings

The DS223j is a compact, diskless two-bay NAS that delivers the full DSM experience, RAID 1 redundancy and low power draw. It's ideal for basic file storage and backup, though its single-gigabit port and limited RAM keep it from handling demanding media tasks.

The Buffalo LinkStation 210 4 TB offers a ready-to-go 4 TB drive, gigabit networking and basic cloud-like features in a compact, low-power package. It's ideal for home users needing simple backup and media streaming, but lacks RAID, USB 3.0 and modern macOS compatibility.

Products in the top-left offer the best value (high score, low price).

Reviewers highlight its plug-and-play nature, media streaming, and energy efficiency, while criticizing the absence of RAID, USB 2.0 limitation, and lack of advanced features.
Users appreciate quick setup, quiet operation and the included 4 TB drive, though some encounter Windows 10 mapping issues and wish for easier HDD upgrades.

“Practically sets itself up - very fast transfer speeds”

“Replaced my old Lenovo NAS - much better and easier to use”

“Could not be mapped as a shared drive from Windows 10”




Professional reviewers view the DS223j as a solid successor to the DS220j, highlighting the faster Realtek quad-core CPU and polished DSM experience, but note the lack of tool-less drive bays and limited media-streaming capability.
Everyday users appreciate the straightforward setup, reliable file access, and the ability to replace cloud storage costs with a one-time purchase, while recurring complaints focus on the noisy fan during spin-down, limited RAM, and difficulties with H.265 video playback.
