Synology Inc. DS223J 2-Bay Desktop NAS 1GB DDR4 Diskless

Two-bay desktop NAS for personal cloud

The Synology DS223J is a diskless 2-bay desktop NAS built around a Realtek RTD1619B processor with 1 GB of DDR4 memory. It provides a single 1 GbE port and two USB 3.2 Gen 1 ports for external storage or printer sharing. The unit accepts two 3.5-inch SATA hard drives or 2.5-inch SATA SSDs using an optional holder and supports a maximum raw capacity of 24 TB.

Home users and small teams needing simple file

This NAS suits households or small offices that want a private cloud for backups, media streaming and document collaboration without administering a full server. Btrfs file-system support adds snapshot protection for shared folders. Buyers who require faster than gigabit networking, hardware transcoding for multiple 4K streams, or expandable memory should look at higher-specification models.

1 GbE network interface limits peak throughput

The only network connection is a single 1 Gigabit Ethernet port, so sustained read and write speeds over the network cannot exceed the throughput of that link. Sequential disk performance reaches up to 736 MB/s read and 796 MB/s write internally, but all remote access is constrained by the 1 GbE bottleneck.
