A Comparison of Synology 4-Bay NAS: DS420j, DS418, DS423, DS420+, DS423+, DS923+

When it comes to network-attached storage (NAS) devices, Synology is a well-known brand for delivering reliable and high-performance solutions. Their 4-bay NAS devices are popular among home and small business users who need to store and manage data efficiently. In this article, we will compare the specifications and features of the following Synology 4-bay NAS models: DS420j, DS418 (replaced by DS423), DS423, DS420+ (replaced by DS423+), DS423+, and DS923+.

DS420j

The DS420j is a budget-friendly NAS device that is suitable for multimedia usage. It is powered by a Realtek RTD1296 processor with a clock speed of 1.4 GHz and has 1 GB DDR4 non-ECC memory. It supports 3.5โ€ณ SATA HDD, 2.5โ€ณ SATA HDD, and 2.5โ€ณ SATA SSD. The DS420j also comes with a hardware encryption engine and a hardware transcoding engine that can handle 10-bit H.265 (HEVC), MPEG-4 Part 2, MPEG-2, VC-1 with a maximum resolution of 4K (4096 x 2160) and a maximum frame rate per second (FPS) of 60. However, it is limited to running only one or two things simultaneously.

DS418 (replaced by DS423)

The DS418 is now replaced by DS423, but it is still worth mentioning. It is similar to DS420j in terms of hardware specifications, but it has 2 GB DDR4 non-ECC memory and supports 3.5โ€ณ SATA HDD, 2.5โ€ณ SATA HDD, and 2.5โ€ณ SATA SSD. It also has a hardware encryption engine and a hardware transcoding engine that can handle 10-bit H.265 (HEVC), MPEG-4 Part 2, MPEG-2, VC-1 with a maximum resolution of 4K (4096 x 2160) and a maximum frame rate per second (FPS) of 60. DS418 is good for multimedia using Synology Apps with h264 + h265 support.

DS423

The DS423 is an upgrade to DS418 and is good for multimedia using Synology Apps with h264 support. It is powered by a Realtek RTD1619B processor with a clock speed of 2.0 GHz (base) / 2.7 GHz (turbo) and has 2 GB DDR4 non-ECC memory. It supports 3.5โ€ณ SATA HDD and 2.5โ€ณ SATA SSD. It has a hardware encryption engine and a hardware transcoding engine that can handle 10-bit H.265 (HEVC), MPEG-4 Part 2, MPEG-2, VC-1 with a maximum resolution of 4K (4096 x 2160) and a maximum frame rate per second (FPS) of 60. However, Plex and h265 seem to be an issue.

DS420+ (replaced by DS423+)

The DS420+ is a mid-range NAS device that is good for multimedia and easy backup functions. It is powered by an Intel Celeron J4025 processor with a clock speed of 2-core 2.0 (base) / 2.9 (burst) GHz and has 2 GB DDR4 non-ECC memory (upgradable up to 6 GB). It supports 3.5โ€ณ SATA HDD, 2.5โ€ณ SATA HDD, 2.5โ€ณ SATA SSD, and M.2ย  2280 NVMe SSD. The DS420+ also has an Intel HD Graphics 600 GPU for hardware-accelerated 4K video transcoding, and it can handle up to two concurrent 4K video streams. It has a hardware encryption engine that can achieve read/write speeds of up to 225/174 MB/s. The DS420+ also features dual 1GbE LAN ports, which can be aggregated for faster transfer speeds, and it supports Synologyโ€™s Snapshot Replication for easy backups.

DS423+

The DS423+ is an upgrade to the DS420+ and is a powerful NAS device suitable for small businesses and demanding multimedia applications. It is powered by an Intel Celeron J4125 processor with a clock speed of 4-core 2.0 (base) / 2.7 (burst) GHz and has 4 GB DDR4 non-ECC memory (upgradable up to 8 GB). It supports 3.5โ€ณ SATA HDD, 2.5โ€ณ SATA HDD, 2.5โ€ณ SATA SSD, and M.2 2280 NVMe SSD. The DS423+ has an Intel HD Graphics 600 GPU for hardware-accelerated 4K video transcoding and can handle up to two concurrent 4K video streams. It also has a hardware encryption engine that can achieve read/write speeds of up to 451/415 MB/s, making it one of the fastest 4-bay NAS devices available. The DS423+ has dual 1GbE LAN ports and supports Synologyโ€™s Snapshot Replication for easy backups.

DS923+

DS923+ comes with an AMD Ryzen R1600 processor with a benchmark score of 3246. It is a 64-bit system with 2-core 2.6 GHz (base) / 3.1 GHz (turbo) and features AES-NI encryption.
