Synology DX517 5 Bay Desktop Network Attached Storage Expansion Enclosure, Black

Product Information

This may be one of those cases of "if you have to ask, it's not for you," but I raise the question mostly because I still really like the idea of the expansion unit and still think it might be something I could make use of - I'm just trying to recalibrate my expectations and figure out if it's still something that could be useful for me. Synology only guarantees full functionality, reliability, and performance for Synology drives listed on the compatibility list. The use of non-validated components may limit certain functionality and result in data loss and system instability. The actual performance may be lower than lab testing figure due to differences in server configuration, deployment, and the number of active operations.

I’m not looking for opinions about the efficacy of SHR1 vs SHR2 vs the various RAID arrays. My question is specific to Plex as I use my NAS primarily as a Plex media storage device.

The performance of the mail system will slightly decrease in high-availability mode due to data synchronization between the two servers. Power consumption is measured when it is fully loaded with Western Digital 1TB WD10EFRX hard drive(s). My Synology DS918+ NAS was set up in February of 2018 with four 8 TB Western Digital Red drives. My video collection took up 17 TB (55%) of the available 30.7 TB of storage. I assumed the 13.7 TB of free space would last a long time (years) since I only buy a few titles per year. At the time of initial installation, my video collection was 71% DVDs, 29% Blu-rays, and 0% 4K Blu-rays.the number of connections that can be maintained when the recommended number of hosted files was reached)

Managed from DiskStation Manager on the host NAS, the additional bays in the DX517 are immediately ready to be used once connected. On-the-fly volume expansion ensures that storage and services on the host are not interrupted during volume expansion.

I have not noticed any speed or performance differences when loading files into the expansion unit or when streaming video from the expansion unit.

Synology will not provide complete product warranty or technical support if non-Synology memory modules are used for memory expansion.

Usable capacity for each volume will be lower than the maximum volume size and is dependent on the filesystem and the amount of system metadata stored.Performance figures obtained through internal testing by Synology.

For example if the NAS or DX Powersupply fails or one of them just stops working, the RAID will be damaged, because suddenly several disks disappear at the same time. This is why i want to separate them. Unfortunately, it is not clear to me how to set it up the right way. I am not sure, if i have to create a separate storage pool with its own volume(s) for the new disks in the expansion unit, or if it will be enought to simply add the disks to the existing storage pool and create a new volume within this storage pool? I think the second option (adding drives to existing pool and creating a new volume in there) will distribute the data from volume 1 and 2 which are in the same storage pool, across all HDD's (These in the NAS and DX517) and will not separate them physically on the Harddrives, right? https://forum.polkaudio.com/discussion/180783/digitizing-my-movie-collection-synology-ds-918-nas-review
