Adding a NVR Dva3219 for home security, also looking at a 1019+ for small business file serving and plex media serving. Is this over kill or can the 3219 handle it all?

Hi !

I'm a french photographer/videomaker and i have a question about RAID and NAS...

I currently have two 4To HDD in RAID 1. These two HDD are mounted on a HDD reader (like this : https://amzn.to/2R0n17e).

I want to buy a 4-Bay NAS and keep the two HDD that i already have and buy two more 4To HDD.

Is it possible to extend my RAID without loosing data from the two disks that i already have ?

I search on your site and youtube channel but i didnt find anything

I hope all is well for you in these complicated times.

Regards,
Michael

Dear Rob,
First of all congratulations for your website, it is very impressive the amount of infomation.
I am selecting a NAS server for home. I come from a WD My Book Live (1Tb) that I used for backups and sotring videos that I play from my TV.
As 1 Tb became not enough and I was worried about redundancy of data, I thought about buyong a new one.
First I tried a WD My Cloud Ex2 but the experience was very bad: noisy and slow, so I returned the product.
From that experience I decided to sutdy a bit more the topic before buying a new one. I saw the new launch of the DS220j and I thought it could be the best option, but after reading your comments, I thought that perhaps memory was going to be a problem and a different model from Sinology or another brand could be a better option (or even wait for the launch of a new model).
Basically, as I said, I work with a Mac mini and a Windows 10 (with usual work done in SSDs); we are a family of 4 so we have some iOS and Android phones and tablets; and also a very new 4k TV.
I would like to do backups in the NAS, copy photos and videos from the phones, play movies on TV... I would like the device to be a longlasting one (perhaps compatible with SSDs in case in the future I want to change to them; USB 3...) as I wouldn't like to feel that I need to change to a different one soon...
Sorry for the long explanation, but your advice would be highly appreciated. Of course if you need more information, please tell me.
Thanks a lot in advance.
Kind regards,
Rubén

I recently bought a 1019+ based partially on your reviews, and so far so good. I saw your post saying I could bump it to 16 GB RAM (https://www.youtube.com/watch?v=BPU_XEepVfM), but I didn't see a link to buy compatible RAM. I just added a Win 10 VM and it's crazy slow and laggy, so I figured my best bet would be to add RAM. I already have a 512 GB M.2 SSD installed as well. Any help would be greatly appreciated.

I run a small 3D animation studio, currently everyone is working remotely which is hard as it relies so much on my staffs own internet connection.
I need some advice on storage as we're running a Qnap TVS-871T on raid 5 over 10GBe. its been great and have changed only a few drives in warranty, but we now only have 4TB left of the 20TB. So looking at upgrading and maybe to a rackmount version. Had a silly quote from Promax for and SSD build that was £16k and don't think its worth it. Also looked at the Qnap TS-832XU-4G which has potential. We only read/write and use it as storage, we don't render or use any other aspects of the NAS. Would love to know a good way to backup to the cloud or at least offsite to my house for that extra security.
Thanks again for your help its really appreciated.

Hello!

I hope everything's going well in your neck of the woods.

I'm trying to figure out a solution for a local network-accessible server to store our video files on and edit from.

We generate around 100GB of source footage per week, and need to store it locally and edit off of the server. This isn't super-high bitrate (around 10Mbit) but I'd like 2 editors to be able to work off the server at the same time.

We need some fail protection, but this data will be backed up offsite once a week.

We have a local 10Gbit network wiring in place, but haven't yet purchased a 10Gbit switch + 10Gbit pci cards for the machines. They're currently running 2.5Gbit.

We have a 25U rack that has around 20U of capacity.

I was torn between a synology solution (something like the rs3618xs) and rolling our own.

For our own here's the parts list I figured out:
- Arista 7050T-64 (48 port 10Gbit switch w/ some 40Gbps connections available)
- Gen 8 server to run unraid / freenas (don't know what components to use, guessed a dual 8core and 128GB ram and host bus adapter that can pump 40Gbps)
- Netapp DS4246 24 bay HDD encolsure w/ psu and network

But I'm not an IT guy, and I'm not sure what to throw in the server, how to set it up, etc.

For the synology we'd do the rs3618 (I think) and add the 10Gbit pci card, but I'm not sure if we can install the nvme caching layer to keep everything speedy.

Unsure what drives to put in, but we were looking at WD red pro 12TB.

Additionally, if we did the build-our-own approach I don't think we want to buy 24 drives at once, so I was hoping we could buy 4 or 6 at a time and slowly add clusters to the entire system. With a 12-bay system we'd just buy all the drives at once.

Thanks for providing this service!

Hello, could you please tell me if QNA-UC5G1T can upgrade a AS5304T nas to 5gb lan?

I have some questions relating to drive expansion on SHR/BTrFS, QTS/Ext4 and QTS-hero/ZFS. On each of these combinations, ...

(1) Can you begin with 1 drive without being locked into JBOD, RAID 0, RAID 1 or RAID 5?
(2) Can you begin with RAID 1, and later, easily change/expand to RAID 5?
(3) Can four drives set up as two RAID 1 pairs be easily expanded to a 4-drive RAID 5?
(4) I know that SHR/BTrFS allows expansion with larger drives without loosing their capacity. Can either of the others do this?
(5) In each of the combinations, if an additional drive is added to a RAID 5, can the data be evenly distributed over the whole RAID? ...easily?

Thank you in advance for the assistance.
