Searching for another NAS

[GabrielFerrazTPU]

Hey guys, how are you doing?

 

I'm looking to buy another NAS (Synology) for my syster and i, i already have a DS1817+(awesome NAS) but i'm going to need another one.

I've heard about a few of them, such as:

Synology DS420J

Synology DS418Play

Synology DS418

Synology DS918+

 

My questions are, the 420J is actually cheap, but can it handle 2 streaming at 4k simultaneously?

With the CPU decoding video? No. But streaming the 4K file over an SMB share, yeah, the bottleneck would be ethernet depending on compression ratio of the 4K file. In theory, should be able to nearly saturate 1gbp/s via file streaming over SMB.

I see, which model would you recommend me instead, if it can handle 1 4k transmission (would be probable mostly a 1080p though) i'm happy with it

DO you need transcoding? How are you playing the 4k file? It can easily stream 4k over smb, but its not gonna trasncsode it. Also what codecs?

Not necessarily, at the moment i have a 10 gig switch with a 10Gbps lan in my nas, but my internet connection is "240Mbps" (i live in a small town)

At the moment i was playing in my DS1817 using X264 / X265

i don't mind using SMB, but i fear it might cause a battleneck in the 1Gbps connection on the NAS.(DS420J)

It really all comes down to whether transcoding is required. 

So depends on the source format and the device you're playing it on. 

 

It won't have the CPU power to transcode 4k for playback. But it will play fine if no transcoding is required. 

If you want to go ahead with the cheaper model, best to make sure the files you source are in the appropriate format for the end device or convert them beforehand.

they'll probably be mp4 using X264

As *most* devices will play x264 MP4 files just fine natively, there shouldn't be any need for transcoding so a cheaper model should be fine. 
If you want to be safe though, go for a 'Play' model.

"The ending letters/characters in a Synology NAS server’s name

This part shows the series a server:

• SE: An entry-level server with the lowest hardware specs. It’s affordable but suitable only for basic needs.
• J: The next level from SE with decent hardware but still quite weak in terms of performance and features.
• Play: A server focused on home entertainment. Its hardware prioritizes photos, movies, and music over other functions. A Play server is always capable of 4K transcoding.
• Plus (+): A high-end server that can do everything a Play server can and much more. Note not all plus servers can do 4K transcoding which depends on the processor.
• XS: A top-tier, expensive server that’s the best of the best. This server is designed to deliver maximum performance and includes the most extended warranty with the best support. It’s suitable mostly for businesses that require high availability and uncompromising performance.
• Slim: A compact desktop server that uses 2.5-inch drives."

Thank you very much, i'll try to find on here, these NAS are quite difficult to buy in Brazil.
