help Synology DiskStation DS423+ FAQ
How many hard drives can the Synology DS423+ support and what is the maximum capacity?
The DS423+ supports 4 drive bays and can accommodate up to 72TB of raw storage using 18TB drives. It supports 3.5-inch SATA HDDs and 2.5-inch SATA SSDs, with Btrfs and ext4 file system options for data management.
Can the DS423+ handle 4K video transcoding?
Yes, the DS423+ features Intel HD Graphics 500 with hardware transcoding support, allowing it to transcode H.264 and H.265 4K video streams in real-time. This makes it excellent for serving media to multiple devices simultaneously without CPU bottlenecking.
What is the maximum amount of RAM that can be installed in the DS423+?
The DS423+ comes with 2GB of DDR4 non-ECC SO-DIMM memory and supports expansion up to 6GB total (2GB + 4GB module). The single RAM slot limits future upgrades, so users requiring more memory should consider Synology's higher-end models.
Does the DS423+ support Docker and can it run Home Assistant?
