Can the DX517 be set up as a backup unit? So that the main data is stored on a DS1821+ and a 1:1 backup is then created on the DX517? And can the DX517 be controlled separately from the main unit (e.g. DS1821+), e.g. in terms of sleep mode, fans, etc.?

Does the DX517 really go into Deep Sleep as described by Synology? Do they stay in Deep Sleep for longer or are they also switched on regularly, even though there is no access to the NAS?

Hello, can I use WD RED PRO 22TB drives on an extension connected to a NAS with WD RED PLUS 8TB Raid hard drives? Is there a risk of losing memory space?

Hello, do I need to buy a cable to connect this extension to a Synology DS920+? Thank you in advance for your reply!

Can I e.g. put 5x20Tb hard disks in here or are there limits?

Hello, is the part also suitable for the DS1522+? The older 15 models are in the list, but the current one is not (yet?). Thank you!

Why do I need a Synology 6G eSATA cable? Is there no cable included with the DX517?

Can I also operate the dx517 with "only" 3 discs or do I have to "fill" all the slots straight away?

What is going on with the prices at Digitec? Various products are suddenly twice or three times as expensive as their own suppliers or competitors.

Can the DiskStation DS418 be expanded with the Synology DX517 Expansion Unit?

When connecting such a unit (DX517) to a Synology (1520+), is it recommended to make a volume over the 5 HDD of the unit or can you expand a volume over the NAS and the unit. I think it is dangerous to run a Raid 5 over the cable!

Woohoo :) Quick question: Is an eSATA cable included with the enclosure or do I have to buy it separately (at this price)? Greetings WW

Salut together, I own several Synology NAS - one of them is the DS413 - I now have to install an extension - according to the compatibility list, the DX513 should fit - is the DX517 (this one) also suitable (is probably the successor model)? In my opinion - due to the eSATA connection - this one should actually also fit, especially as the DSM versions are up to date. Thanks for a short info bg Rainer

hello all Maybe I haven't looked enough, but I can't find any information about the size of the fixed pallets to be used. 3.5 or 2.5 inch? (I recently bought the wrong enclosure and had to return it, 2.5 instead of 3.5"). Sorry and thanks for an answer.

Hello all. I have a DS216se and am running out of storage space. Does it make sense to buy a DX517 and is it compatible with my Diskstation?

Is this compatible with the Synology DS1817+ (not listed)? Is there an alternative expansion with more hard drives? Can WD Red with 8TB be used?

Hello Digitec Community, Does anyone know if it is possible to set up a dedicated power schedule for the DX517 on the host DS? I really only want to use the 517 as a backup and therefore only start it once a week, make a programmed backup, then shut it down again automatically and leave the host DS (918+) running of course... LG And thx!

Hello Digitec Community, I have a DS1515 with the DX513 expansion unit in use. Now one HDD is defective in the expansion unit. At least I thought so when I replaced it, the error was still there. I now strongly suspect that my DX513 is defective. Now my question, can I remove all the HDDs and install them in the DX517 without losing all the data? I am currently making a current backup just to be on the safe side.

Good day According to Synology, the DX517 has a 3-year warranty. Why is this not passed on at Digitec? Greetings Spaci999

Does it also fit the newer Synology 1018+? This is not listed...

If I want to use the DX517 as an extension for the DS1515+ (with 5X6TB), can I also use smaller or larger disks or do they have to be 6TB?
