ReadyNAS 4312S: Operating Temperature
Model: Netgear RR4312S6-10000S ReadyNAS 4312S, 10Gig SFP+ 2U 12-bay Network Attached Storage 12x 6TB Enterprise HDD
According to datasheet 2016 Operating Temperature is 0 to 40 °C
According to datasheet 2017 Operating Temperature is 0 to 45 °C
I am interested in NAS 12x 6TB HDD.
Which Range is applicable?
Is there an option for up to 50°C available?

Those figures are for the Operating Environment i.e. the room where the unit is installed

Re: ReadyNAS 4312S: Operating Temperature
So in 2016 we could operate the NAS at 40°C and in 2017 at 45°C ??
What about 2018?

http://www.netgear.at/business/products/storage/readynas/RR4312X.aspx#tab-technischespezifikationen
-> RR4312X, RR4312S Datasheet is 2016 -> (40°C)
https://www.netgear.com/support/download/
-> Product Data Sheet is 2017 -> (45°C)
https://www.netgear.com/business/products/storage/readynas/readynas-rackmount.aspx#tab-resources
-> ReadyNAS® 3312/4312X datasheet is 2017 -> (45°C)
Is there a difference between SSD and HDD ?

The NAS generates heat, so it will always run hotter than the ambient temperature. Using drives that are more power-efficient does reduce the system and drive temps.
SSD power use varies considerably by model, often ranging between 1 watt and 4.5 watts under load. This overlaps the HDD power use - NAS purposed and enterprise class drives generally run between 4 and 6 watts.
The operating temperature range of the disks also might be a consideration. Many SSDs are spec'd to run at 70C, hard drives are usually spec'd at 60C.
So you'd need to check the specific specs of the drives you are considering, and perhaps take both power and the operating temperature range of the disks into account.
How that relates to the data sheet is a bit hard to say, since there always is some margin built into those specifications. But whatever disks you choose, it's best to stay under the current datasheet's ceiling (45C).
How hot are your ambient temperatures? 45C is pretty hot.

Re: ReadyNAS 4312S: Operating Temperature
We need to run the NAS in an environment of 50°C.
The capacity (netto) should be at least > 50 TB.
Speed is not that important. 50 MB/s would be fine. (10Gb/s interface is oversized).

I think that rules out SSDs (since the largest sizes generally require SAS, and not SATA).

Definitely over the spec, and I'd be concerned about the disk failure rate of HDDs in that temperature range. Even though the disks are spec'd to run at 60C, there is some evidence that the failure rate increases significantly if they are running at 50C or above.
I suspect Netgear wouldn't guarantee operation at that temp, and likely would void the hardware warranty for a NAS running outside the operating temperature range.
I suggest using an air-conditioned server rack.

Re: ReadyNAS 4312S: Operating Temperature
45°C is the highest ambinet temerature we have done with the test.
