Re: F4-220 FW 4.2.18 no HDD sleep

Post by rdtsc »

In 41 years of running / building / programming / repairing computer systems, it is my opinion that traditional (spinning platter) hard disks seem to last longer when left "on" continuously.

Perhaps this is just me, but I've had a dozen or so disks fail, and seen many more, which were all in power-cycled or sleep applications. I think it is the thermal stress - heating / cooling causing expansion / contraction - which contributes to premature failure.

In one machine I have two 80GB SATA server disks (bought when SATA disks were just catching on) in a RAID0 stripe. It's probably comparable to a modern disk in terms of speed, so nothing special, but it was really nice back then. And it has been running (in several machines) ever since... for 20+ years. It is never shut off, and the disk temperatures are always controlled. I keep them running now as a "downloads" drive, just to see how long they will last.

I'm hopeful that the (modern, expensive) disks in my TNAS fare as well. So I set the TNAS disks to never sleep, and set the fan to Medium, and that seems to (now) keep things evenly cool under tested conditions. But I would personally like more control of the fan settings, such as "keep disks at 30°C always."

Of course, it will cost electricity to run that disk. I estimate that one (spinning platter) hard disk, active 5% of the time, will produce about 5.6W of waste heat. From an 80% efficient power supply, that means 7W from the outlet. Times 24h, times 7 days, times 52 weeks = 61kWh of electricity per year. If each kWh costs $0.10, that's $6.10 per year to operate that disk continuously. Which would be nice to reduce. Except that, either way - after a few years (power cycle) and cost of new disk, or many years (continuous) and the extra electricity - the total expense will end up about the same. That's why I choose continuous operation: longer data retention and less work for the operator, but higher electricity bill.

Best wishes.

Same here, it was working w/o problems until this 4.2.18 update.
TerraMaster F5-421, 1 SSD, 4 HDDs.

Really a pity, because 45 Watts makes a different compared to 15 Watts before with only one wakeup once a day.

My F5-422 never goes to sleep either.

Only use this for casual data storage and Time Machine and the thing is noisy as hell!

Would be great if it did go to sleep!

the only way to make the hard drives sleep is to put the fan on low

Great, this helps! However, HDD temperature has to be monitored until a real fix has been published.

BTW: 30 Watts difference may seem to be not much, but with 24/7 this sums up to 260 kWh, which is not cheap, at least here in Germany :roll:
FYI: 1 kWh costs about $0.40

Thanks @addx972!
I can confirm that configuring fan speed to low enables HDDs to enter sleep mode.

@Terramaster, until 4.2.16 HDDs were also put to sleep with "Smart fan" setting.

4.2.15 seemed to fix my sleep issues. I just double-checked the logs and they're definitely going into sleep mode looking at the numbers.

I haven't tried doing so yet but just curious, can we go back to an older TOS if the latest one doesn't work correctly???

TY for the reply!

This is the first time this machine has been running well, too nervous to try upgrading, thank you for clarifying!

Hi,

HDDs not sleeping again after updating to 4.2.28 + Patch 1.31!
No matter what is configured either fixed fan speed (low | medium | high) or automatic which was working until 4.1.18, HDDs do not enter sleep mode.
