Ok. I asked this question earlier and got a reply. "The website for Qnap shows that I can use the ts-453d with 8 cameras on a home surveillance system. Qnap says it needs 8gb ram to do so. But the 4gb specs say it will transfer 160 GB per sec, and the nas surveillance calculator shows I will need something like 48gb per sec. Can I do 8 cameras with 4gb model (I plan on upgrading to more than 8 at a later date)?"
The reply I got is "IP cameras themselves do not require extra RAM. You can have 8 cameras recording with 4GB RAM with no problems. You need RAM for playback. It also depends on which software you will use to operate your cameras. If you use Surveillance Station, this app do not need much resources to run and operate. If you are looking at QVR Pro then this app will require some more resources then the other app mentioned. QVR Client is a desktop app for your computer. The requirement for 8GB RAM is mentioned for your computer if you refer to this : https://www.qnap.com/en-uk/software/qvr-pro
Either way, whichever software you choose to use, you can upgrade RAM capacity at any time in the future."
I have another question. So the 8gb ram requirement is for my home computer? I have never used a nas, but think the features of one (qumagie, qvr pro) are phenomenal apps. So just to be clear, using the qvr pro software, if I get the 4gb ts-453d, and have a home computer with more than 8gb of ram, I shouldn't have any problem? Does this apply to the hdmi output of the device as well? What i want to do is have the 453d in my garage inside a large safe. run a cat6 cable to my router, to be able to access it from one of 3 computers. all will have more than the 8gb of ram. when i get all of the cameras i want for a surveillance system, is all i will need then a switch? sorry for so many questions, just havent done much with networking before, but I think a nas is the best solution for the cost in my case. Thanks in advance. Also, does NasCompares have affiliate links for purchases or a patreon?

Hello i currently have a ds1621+ with a 4x10tb drive shr-1 array with 13TB of data on it. i purchased a QNAP TVS-672N and i intend on putting a raid 50 on it. However i will need to utilize the 4 drives that are in the synology atm. My question is .....is there some way to CHEAPLY offload my data temporarily to another location and then pull it back once i have built the new array. atm all i can think of is to put my data on a 10tb and 4tb drive i have in desktops around the house.

I've found 3 NAS Compares Setup Guides so far. Which one is best to guide me with my DS1621+?

Wondering if there is a limit to the number of 1080p cameras the Synology RS819 or RS820 can support in Surveillance Station

Will 5900RPM drives play nicely with 7200RPM drives, or will something go boom?

I've got a 920+ with 4x 4TB 5900 drives running SHR1. I'm going to need to expand my storage soon, and I already know I don't want a DX drive (I'm not comfortable with losing another whole drive for parity if I create another volume, nor am I comfortable with a single volume reliant on a single sata cable, though feel free to try and change my mind on that point). My options are a) buy larger drives and swap them in for 2 or more of my existing drives, or b) buy a second box and more drives and manage them in a network.

Right now, option b is a bit more costly than I want to go, and I was hoping to swap in 2x 8TB drives now followed by 2 more later in the year, or maybe buying a 2-bay box for the spare 4TB drives.

After having read up on this, it looks like 8TB drives only come in 7200RPM flavour, and it's not advisable to mix RPMs. I have two questions on this. 1) Is it possible to mix the two RPMs, and if so, is it viable for medium term (i.e. could any potential faults/damage accumulate over the next 6-12 months or so?). 2) With SHR, will either of the 2x 8TB drives actually offer their full 8TB of space if mixed with 2x 4TB drives?

Thanks to all for any help you can give.

Cheers!

I've added a 16 GB module to my Synology DS920+.


It all seems to work very well, but the Virtual Machine Manager still says I have only 4 GB available on my host. See attached image. Any advice on why this is happening? The main reason for upgrading, was to allocate more RAM to VM, so it is quite a bummer.


I'm using Kingston DDR4 - 16 GB - SO DIMM 260-pin. Part number KCP426SD8/16.


(Thank you very much for your advice on the unofficial RAM upgrade option! And all your advice on Nascompares in general!)

Hi All - I've just upgraded from my VERY basic 213J to a 720+...needless to say, it's like night & day.

I had 2x 3TB drives originally, but one failed a couple of years ago, replaced with a 4TB. I set them up for maximum storage rather than have redundancy, because the NAS was used as a back up for my PC

Now I've found how much you can do with a faster NAS, I'm thinking of replacing the 3TB with a 6TB and having it as back up for all 4 of us in the house. I'd still use my 100GB Google Drive account though as an additional off-site solution for my pics & vids of the kids growing up etc....as my NAS box is just a few feet away from my main PC, so a house fire would mean precious memories would be lost forever!
Looking at the drives in DSM I can see the larger 4TB drive is about 60% used, the smaller 3TB drive only 8%. What prep would I need to do so I can replace the 3TB with a new 6TB....is it even possible without having to start from scratch & re-copy everything over again from my PC?
Thanks for any advice....

I've found the information you provide on your site and on videos posted on Youtube very helpful. Thanks for your work.

I'm new to music streaming. I have a SONOS PORT device that I'm using to stream from Spotify. Next step is to rip the ample (600-700) family CD collection and move the data to a NAS for streaming purposes. Based on the information I've seen you present and what I've seen on the Synology site, I've been focusing on the Synology DS220+. 3.5 years ago in a video you posted on the subject of choosing a NAS for purposes of streaming with SONOS devices, you suggested the DS216+ as a viable option. In the intervening years, is there any new information to indicate that the DS220+ isn't a reasonably equivalent choice? Is there something else you might suggest I consider? I also plan to use this device for basic backup of family computers (including a fair number of photos that I'd like to organize), of which there are four.

Besides the additional capacity, does the DS720+ give me anything, feature-wise that might be useful enough for me to consider?

I reside in the U.S.
Thanks in advance.

Family has 4 phones, 1 iPhone and 3x Android. I wish to use the NAS to store all photos [currently on Apple and Google} and free up memory on the phones. Caveat, I am not very technical...

I am about to by my first NAS. But I can not find good information about some details that are on high priority to me.

I want:

* Instant upload of iPhone photos and the possability to have them deleted automaticly from iphone after uploaded.

* iPhone Live Photos support (on auto uploaded photos and browsing photos)

* to be able to use my iPhone to browse my photo collection stored in my NAS. I plan to have nothing locally stored in my phone so there will be plenty of space for a big cache files for thumbnails.

I am comfortable with configuring systems but can not really say what NAS brand that I want. But if one of them are better on my wishes above - that will be what I go for.
