Can have 3 individual with their own space. Create everyone each their own account and their folder, then allow each account to only read & write their own folder. You also can set each folder can only occupy how many GB/TB space.



See this to understand how HDD, storage pool, volumes and folders work with each other. Start from bottom, Disk is the how many HDD that you have in the NAS. From there you create storage pool, this part you decide what RAID type you want to use, different type of RAID affect how many space you have. Example if use 4 HDD and set RAID-10, you only have half the space from HDD capacity, if set RAID-5 or SHR you have 75% of the space from HDD capacity. After that you create volume, you can create one or multiple volumes. After that only you create folders on which volume that you have.

If use Windows as comparison, folders in NAS are like partition that you create from HDD in Windows. Volume in NAS are like the HDD in Windows. NAS have another layer that is storage pool which is cumulative of the HDD that you have.

Usually seller sell NAS without HDD. Some do bundle with HDD but unless the price is cheaper it's better to buy separately.

Synology got Photos and Moments app that for upload photos and videos as well as managing it

Wow 50TB of external storage

You have a lot terabytes of data that is not important and can be replaced if damage/missing, and some important data that irreplaceable? If so then I suggest use 2 HDD for redundancy/RAID for the important data while the rest is just a bunch of disk, no redundancy or backup. This way it doesn't cost so much for those not important data.

As for the NAS itself, you can go pre built like Synology or built yourself. Usually if need until 100TB it would be cost effective to built yourself, but need source each component for NAS use by yourself, learn how to install the OS and setup everything. Need some technical skills. But since most of the data is not in RAID, you can go 6 or 8 bays pre built NAS, 2 bays in RAID-1 for important data, while 4/6 bays each as own volume, this way you can use it as hot swappable, take out currently not need HDD and put in another HDD that you want to access. This way no need to get much more expensive plenty bays NAS while still can have 100TB now and expand in future.

For HDD, price per TB, now 8TB is the most lowest. Toshiba N300 is less than RM900 while Seagate Ironwolf is less than RM1100. Not recommend to get WD now because it might be SMR drive.
Depend on your external storage HDD in it, some if it using normal HDD inside, you can take out the HDD and use on NAS.

For NAS, if you built yourself it might cost around RM2000+ if everything is new. If prebuilt, 6 bay NAS I like DS1621+ hardware, price can get around RM3600. This comparison show how much more powerful the hardware is. If 8 bays NAS, DS1821+ still not yet selling in Malaysia, DS1819+ (around RM4500) hardware also not bad but random read/write not as fast as DS1621+.
DIY NAS pros is cheaper and can customized everything. Cons is need technical skills and time.
Prebuilt NAS pros is not much technical skills need to setup and maintain, everything is mostly automated. Cons is the hardware is more expensive, cannot upgrade.

Usually can last around 5 years, but actual is depends on usage, how take care, type of HDD.
Best is get NAS HDD, as it design for continuous running and have vibration protection.

Important as in the data cannot be damage or missing? Then you will need store in system which have checksum to maintain it's integrity such as RAID-5 or BTRFS. You also need to have backup of the data. If use prebuilt NAS get at least 8 bays. 8TB HDD won't cut it anymore. 12TB HDD x 8 you will have 84TB usable space if use SHR-1 or RAID-5, this method 1 HDD failure you still can replace it and get back all data. But too many HDD means chance of more than 1 HDD failing is higher, use SH-2 or RAID-6 can have 2 HDD failure and still get back all data, but this RAID type only 72TB usable space. You also need to get additional HDD as backup copies. So maybe around 12TB x 8 for storage and 8TB x 7 for backup.

If it's just video where file integrity is not really important, example if some bit-rot, the video will have glitch on some time frame, it's still acceptable. Then you can just use each HDD as own volume without any RAID, then get same total capacity of HDD for backup so that when main HDD fail you still have another backup.

If the data is super important, best practice is to have 3-2-1 backup rule. Have 3 copies of the same data, at least have 2 different storage media (another in dvd, bluray, tape drive) of the 3 copies, and store 1 copy offsite (in the cloud or at other home/location)

Initially I thought not important data so can use hot swappable method and use 6 or 8 bays, then it leads on from there. Now you mention it, 12 bays will be a better choice.

Really similar like having platinum credit card?

Usable storage if SHR-1/RAID-5 is 144TB, but since 10 HDD pool, having 1 HDD failure protection is kinda risky. SHR-2/RAID-6 would be better.

If buy few HDD first and in future keep adding HDD with different size, it would be better to use SHR since it allow to maximized the pool according to HDD space

It seems there's no way in DiskStation to set a HDD as removable drive? I doesn't find if there's such option.

It's a RAID type, develop by Synology and only usable for their NAS. Classic RAID type size limited by the smallest HDD in the pool. SHR can maximized the storage without being limited by the smallest HDD. Can read here to understand more.
https://www.synology.com/en-global/knowledg...Hybrid_RAID_SHR

I guess that is a no?
Something like this MyArchive
Internal HDD can be used as removable storage for keeping additional storage.
I guess having external HDD reader + internal HDD also can achieve same thing, only need additional hardware.

For the removable drive bay, it can't be part of RAID. Example usage on 4-bays NAS, 3 HDD in RAID, 1 bay for hot swappable HDD.

Is there anything on DSM that indicate you can create pool/volume that can be removable?
I can't find such options. I google also can't find it got such function.

Unless your work files in GB size every time upload/download, 100/50 MB is enough. Depends on model, some can add/change RAM.

No. That's hot spare. eg. If assign one of the drive as hot spare, once one of the HDD in RAID died, the OS will auto use the hot spare as replacement for the dead HDD.

i've written Synology DS920+ Review here

That price is really tempting. And WD so far no SMR drive for 8TB.
I believe its fairly simple to shuck it since a lot US people been doing it.

One con is if drive any issue, not worth the cost to send back.
Another frequent occurrence with Amazon US is receiving returned drive that have been shucked and replaced with smaller size drive.

Mine is 4GB solder on and 1 free slot. Synology list as can install max additional 4GB. But other have even install 16GB without issue.
I more modest, only go for additional 8GB



To confirm no memory error with the RAM, run an utility that will check the RAM. Forgot what the program called, it run on Windows and will put the NAS into some sort of checking stage until it complete the checking.

Even running few days might not detect the error as RAM not fully utilized. I read someone able to detect RAM error by running VM windows 24/7, every time after few days it will crash. Then when change another model RAM it's VM never crash even after 1 week.

I didn't buy official RAM. Synology list this NAS as max 8GB only and only selling 4GB for this model as another 4GB already soldered on, even intel list this CPU as max 8GB. But others have installed 16GB + 4GB soldered = 20GB

RAM no need to be in pair. But this NAS very finicky, same speed same latency also might not work. I search for brand and RAM model that others have successful case.

Anyone using Synology Photo Station and Moments to create albums in 1 user and share it with other users?

I'm trying to create shared albums that will appear on all selected users Moments app so that they can access it on their phones. So far still haven't figured it out, rough idea is have to create albums in Photo Station then share to other user Photo Station, and change settings on other user Moments.

I wish DMS 7 stable can faster be released so that can just use 1 Photos app instead of going around 2 apps.

And don't know if Synology wrongly implement or Google making it difficult for them. Everytime when edit user, Google will auto fill username and password into email and password column, everytime have to delete the entry for email and re-enter password when edit user. In Drive and Moments app also same story, it will entry into wrong column, username is entered into domain/QuickConnect ID instead.

My main objective is so that multiple users can use only Moments app on their phone to access shared albums. They not going to use the web-based Photo Station.

Now trying to understand how to share to other Photo Station then also how to make it appear on their phone's Moments app.

Main advantage is they can access it from their phone, no need use computer. It's very similar to Google Photos, can access from PC but most of the time everyone access Photos from their phone.

I can just take the easy route, copy all files to each user's folder. But that will create a lot duplicate files, not to mention hundreds of GB space.

I'm not sure if they can mess up my Photo Station album, which will be a problem since everyone will access the same file.
But I got saw there's option to disallow files to be modified by shared user, maybe any changes will only be on that user own metadata, without any affect to the original file.

You mean access it by phone's web browser? I tried it just now, yeah can access it but not as smooth as Moments app on phone. Using Moments it feels very similar to using Google Photos.

Another advantage of using Moments on phone is it can directly backup the phone photos and videos, so it's an automated process on the phone. Like mine now, I set DCIM as folder to backup (it also can choose multiple folders to backup). After it complete backup I can choose "free up space", which it will proceed to delete all the photos in DCIM folder. I can let it remain in Moments folder if I don't want to share with others or I can copy/move it to Photo folder which will auto share it to other users. All other users also can auto backup their photos, and then I can move the photos to shared folder.

Finally figured out how to configure the sharing options. Each user must have access to Photo Station and Moments app in DSM. After copy photos to Photo folder (Photo Station working folder), in Photo Station I need to assign privileges to each user which folder they can browse. After done that the user can access by their own Photo Station and also by changing to Shared Photo Library in Moments web-portal. In Phone app, they have to change at Source of Photos to see shared photos.

Let's say your DDNS name is HandsomeDupe, and you choose synology.me as the service provider. So your web address is "HandsomeDupe.synology.me"
Then you also need your DSM ports, let's say it is 5001 for https, so the address would be "https://HandsomeDupe.synology.me:5001"

Additionally, go to Control Panel > External Access > Router Configuration, and click Test Connection to see if the connection is ok.
