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?
I will be looking for a new Synology rack mount NAS in the first quarter of 2021. I have a a DS3615xs offering ~87TB available storage (10 x 12TB drives RAID 6). About 50TB is in use. That machine runs a Plex server offering movies, TV, music and audiobooks. It also runs Cloud Sync to copy data to Google Drive, Hyper Backup to backup to a DS1010+ every six hours via Rsync, Cloud Station, and Synology Chat. The DS3615xs has a number of CIFS shares on it as well as an NFS datastore for vSphere. It's connected via 10G Ethernet.
I want to replace that unit with something higher-performing, newer, and rack mountable, since all my servers and most other devices are now in a rack. The DS3615xs would sit on top of the rack and serve as a backup target or node in a two-node Synology cluster, if possible.
I am looking for 10G connectivity, M.2 NVMe caching and good performance with NFS and iSCSI as shared storage for a vSphere cluster.
Can you assist with a recommendation? Thank you.
Hi, Please can you help a noob.
I have an 8-bay Synology DS1815+ (out of warranty) which has failed to power on after a reload. I tested and tried new PSU - no blue light - no motherboard. So I'm resigned to get a replacement Synology NAS (I'm using SHR).
I've seen the excellent youtube vid comparing DS1621XS+ and DS3617XS.
In my DS1815+ I have 8 drives: 4x6TB, 2x4TB and 2x18TB WD181KRYZ Gold new drives). The config uses SHR - with two volumes (6 disks and 2 disks).
The questions I have:
I) Will I be able to migrate to a DS1621XS+ by first installing just 6 drives (one volume) and then slowly reducing the number of disks to enable to add second volume
ii) If not, will I be able to use a DS1621XS+ (6 bay) + expansion (DX517) to facilitate an initial migration to the new platform. I appreciate long term best not to have a volume split via eSATA.
iii) or am I forced to use an 8 or more bay chassis for the initial migration.
Really appreciate your help with this
QNAP TS453be vs Asustor AS5202T
I am new to NAS and looking at my first purchase. In short, I would like to be able watch media locally by HDMI using a service like Plex, have some further space for backing up material and have the ability to access the drive over the internet. I think my budget will extend to a 2-bay NAS and I expect my initial storage to be 4TB in RAID 1 or 6TB in RAID 1.
After much research, I think i have narrowed my choice to between the QNAP TS-253Be and the Asustor AS5202T. I am having difficulty in deciding which to opt for. In support of the Asustor, it appears to be a little cheaper, it supports HDMI 2.0 (and so can play higher quality media and is somewhat future proofed over HDMI 1.4 in the QNAP), and it has DDR4 RAM. The QNAP appears to have a more powerful quad-core processor. Further, though I am less clear on this, I think the QNAP better supports its HDMI output.
