Basically, a Synology NAS with the appropriate configuration (e.g. drive) can be compared to a cloud subscription. Note, however, that the speed of access depends strongly on your internet connection at home. I'm currently running a DS414 with 50Mbit/s upload and access to photos is possible but not very exhilarating unless thumbnails are generated beforehand. With a synchronous 1 Gbit/s internet connection, the speed should not be a problem.
hello 80401230
if you need data regularly, the access will be faster because the data is read from the ssd-cache. but probably only makes a difference with heavily used nas. with one ssd you can set up a read-cache. with two ssd's a read/write-cache. on the syno-homepage everything is well described.
greetings rené
ps i tested your mentioned ssd from samsung in a smaller size. works fine.
You can cache on a read-only volume with a single m2 drive or read/write with 2 m2 drives. Not for the OS, at least not officially.
Afterwards, if you find the OS slow, you can add more RAM and remove memory compression (16GB recommended).
The only solution is to do link aggregation ( https://fr.wikipedia.org/wiki/Agrégation_de_liens ). The DS918 does it, you need a compatible switch, a network card with 2 compatible Gigabit ports on the computer and 2 Ethernet cables between each device.
Not to mention the knowledge needed to configure this mess...
I know that there are NASs that have HDMI outputs, but they are the exception rather than the rule. The NAS is more like a hard drive on the network that you can access from different devices. Then there are apps like DS Video or Plex that can be used to stream media from the NAS. But you need a Smart TV or a device like a Chromecast, Apple TV, Nvidia Shield TV or similar.
No, this is not possible, two NAS cannot be connected together and operated as one system, for this you need a hard disk extension, such as the DX517. It is compatible with the DS918+ and offers an additional 5 storage spaces (this is also the maximum that a DS918+ can use, the 9 in the DS918 stands for a maximum of 9 disks and the 18 stands for the year of release).
Synology DX517 Expansion Unit
If the failed disk in bay 2 is replaced, it can be reconfigured as a hot spare.
Or dissolve RAID-1 and reconfigure with disks in bay 1&2 and configure disk in bay 4 as hotspare (backup recommended before).
Unfortunately, under your two models is not simply done with two mouse clicks. You can find detailed instructions here: https://www.synology.com/de-de/knowledgebase/DSM/tutorial/General_Setup/How_to_migrate_between_Synology_NAS_DSM_6_0_and_later
Hello, you can connect it via the address "servername.quickconnect.to".

I ordered the "Samsung 970 EVO (500GB, M.2 2280)" and it works great. How big the ssd has to be depends... If you already have a synology and buy it as a replacement, then you can charge for it.
The cache sizes are per slot, so two M.2 with 1TB each is fine. Furthermore, according to the synology website is the DS918+ also compatible with 2TB M.2 SSDs. => https://www.synology.com/en-global/compatibility
Not sure what you mean by the second question.. Yes M.2 NVMe drives are supported if you mean this. => https://www.synology.com/en-global/knowledgebase/DSM/tutorial/Storage/Which_Synology_NAS_models_support_SSD_cache
No, it didn't, the additional 4G RAM can simply be inserted into the free slot.
Regarding warranty, Synology writes "Do not remove the pre-installed memory module to avoid voiding the product warranty" and " Synology will not provide full product warranty and technical support if a non-Synology memory module is inserted.
memory module is installed that is not from Synology."
So as long as you use a Synology RAM you are on the safe side. If you want to install 16G RAM and therefore use non-Synology RAM (iDomiX discusses this on Youtube, the videos are generally worth watching), you violate the warranty.
Hello together
Two questions:
1. my 918+ won't boot up anymore. The power was gone or the fuse was out when I got home (which I find a bit strange in itself) - I was able to restart a second device, a Synology extension, normally. This is probably not enough for a remote diagnosis, but if anyone has experienced something similar, I would be very grateful for any information.
2. I bought the device in February 2018, the warranty has expired and apparently the associated power supply is no longer available ("Adapter 100W_2" according to Synology support page). Does anyone happen to have another suitable power supply in use that I could try for this without hesitation (the extension has a different plug)?
Thank you very much for your support!
Is there anyone out there who can answer my question:
RAID1 in bay 1 and 2. In the last bay, a hotspare disk that simply integrates itself directly into RAID 1 as soon as a disk fails.
Question: Now RAID 1 in bay 1 and in the last bay = unattractive. What happens if I replace the failed disk in bay 2? Does the hotspare then become the hotspare again or does bay 2 become the hotspare? This is a complicated question that I couldn't find out anywhere on the internet. Otherwise I will have to carry out a practical test.
Thanks =)
I doubt that this is possible. With a Synology NAS, the DSM (DiskStationManager) operating system is installed on the hard disks. It will be similar with the QNAP NAS. I think it is unlikely that the Synology NAS will boot without errors with the QNAP operating system.
The best thing to do is to use a SATA2USB adapter to back up the hard disk data to another drive. (Instructions for this are available on the net). Then reinstall the new NAS with the old disks and restore the backup. Alternatively, ask the manufacturer if you can buy the power supply separately as a spare part.
