DS423 PLEX compatibility and performance

As of today, there is no Plex installation created for this CPU. When we can we will test a package made for RTD1296 ARMv8 which is a package for 64-bit CPUs. 

We can expect this NAS to be able to handle 1080p video transcoding in Plex. Maybe even a tiny bit of 4k (very simple files).

DS423 HDD compatibility

Synology drives (Toshiba) have been tested up to 18TB capacity.

Compatible WD drives

WD drives have been tested only up to 14TB capacity. Only Red plus and Purple drives have been tested so far.

Compatible Seagate drives

Seagate drives have been tested up to a capacity of 12TB. This included Skyhawk and Ironwolf drives.

Can I use drives (HDD/ SSD) that are not on their list.

Yes, Synology have promised that Plus and Value series NAS such as this will have no software lock on drives that they have not tested and added to the list. There might be a warning message that drives are not from the list though. Their support level might change based on this.

Conclusion

Overall quite disappointing. The only real big change is an upgrade for the CPU. Keeping the old 2GB RAM will make a lot of people run into memory issues. People will need to fill those HDD bays with SSD to cope with a situation when RAM overflow use HDD/SSD volume to store temp data. Also the how swap option from the front panel is removed. Now you need to break the NAS open just like DS420j to change a drive.

Thanks to the faster CPU, you will be able to transcode more of the 1080p content. And maybe even a tiny bit of 4k in Plex. Using Synology Video apps, you will be able to handle 4K just like with an older model.

Synology h265 encoding removal few months earlier will still affect remote access for videos in this format. Including CCTV remote access and videos via Photos app.

  1. Update 15-03-23, I have found out since this video was recorded that the chassis of the Synology DS423 is going to be using the J series casing (as seen in the DS420j, DS418j, DS416j, etc). I have updated the thumbnail for this vid and the details in the article linked here – https://nascompares.com/2023/03/14/synology-ds423-nas-revealed/

  2. Would this be considered a good entry into synology as someone currently without any NAS? This would be a step up from the J model as far as what it can run on the DSM software is my understanding. 

    I am considering just a DAS as well, but then I get hung up on speeds and RAID software and all that as well. Considering OWC Mercury Elite Pro Quad (USB C 3.1 gen 2). End of the day I would like a 4 bay, Raid 5 (or SRH) system to update my backups and storage system and would use four 4 TB drives unless the next sizes up come down in price to close the gap.

    Currently running M1 Mac mini with 512 GB internal. I have an old 1 TB drive on Time Machine duty, as well as a drive pulled from my old mini that I do a CCC backup each week and store in firesafe.

    I also have two old 2 TB WD essential drives that hold old media files from back in the day when I ripped all my dvs and streaming was still a crappy option. One drive clones to the other each morning as a backup using CCC.

    A new NAS/DAS could take over these duties, freeing up the older drives as some redundancy backups or something. I do use iCloud for my entire user documents folder so it’s all synced and accessible on iPhone and iPad.

    *edit* strictly person use for files and backup.

  3. Just Wondering if you will do a video on WHen you should upgrade? I have a DS918+ along with the expansion unit and I mainly use it only for Emby Media I have over 5 Thousand movies and I am looking to get more and more Blu-Rays. Can My Collection get too large??

  4. Well for those of us that are still on the two bay 200 series and want an upgrade but the 923+ is out of budget, then this is a good alternative. Thanks for all your hard work.
