TVS-H674-i5 NVMe OS Size Requirements

Hi,

I currently have a TS-653D running on 4xWD Red Plus 10 Tb hard drives in RAID 5. Latest QTS 5 O/S. I am planning to purchase a TVS-H674-i5 with 2 NVMe drives running RAID 1 for the O/S and apps. Will most likely use this as a Plex server and data storage.

Will a 1Tb size suffices? Some people say 500Gb is enough, some people claim 2Tb is the bare minimum. Any specific recommendations for any models: I was thinking SAMSUNG 990 EVO Plus (which is also on the compatibility list)

Are there any other things to consider?

The OS is always on all internal drives, the system volume (apps) can be put on SSD, but needs a complete reinstall.

If you plan on a lot of writes, make sure you choose a high endurance drive model.

I have 2 1tb 980’s in a TVS-h1888x OS and lots of apps also 130gb of files and there is still 533gb free. So 500gb if nothing but OS and apps.

@dolbyman I plan on setting up the new NAS with the NVMe as storage pool 1 for anything non-data related. When I am good to go, I will create a new RAID 5 storage pool for my 4xWD Red 10 and restore my personal files. Does that makes sense?

@Franklin thank you. Seems that 1tb should be sufficient!

Sure, that process will work fine … as soon as you put the HDD’s into use tough, they will also get a copy of the OS partition, so no speed gain for the OS.

I think I’ll get the Seagate FireCuda 530R NVMe which has good endurance for a consumer model.

Make sure it is on the approved list.

It surely is! :slight_smile:

I get it that the OS is distributed onto every drive in the NAS (NVMe and HDD). But if the NVMe is designated as the “System” pool … doesn’t that help the NAS get at least a bit of speed gain for the OS? And isn’t there a benefit of having the HDD’s not designated as System drives (even though the OS is distributed to them? Just curious about how this all works and whether the “System” designation does anything at all.

It certainly helps installed apps, as they are exclusively (some can be moved) on the system pool. SSD also get a dedicated swap partition that is used preferably by the OS.

I have my new NAS pretty much setup, running exclusively from NVMe as of now. It’s pretty snappy, actually! I like it.

If anyone has any other tips for NVMe, I am all ears!

Depending on your NAS model the specs will say something like GEN3 X4. Make sure your M.2 is at least that fast.
