Welp, back up and running. The only major casualty are my virtualbox images. Hopefully the drives aren't corrupted, but the .vbox files sure don't want to work anymore.

ooh, my new drives have a "Helium Level" SMART attribute.

how the fuck they gonna measure that? They have a double casing with a helium leak detection circuit on the second shell?

it floats duh

If you start talking funny, it sets the alarm off.

I bet they have a barometer inside the shell.

edit: actually probably not, since Pv=nRT.

Who's drives must be a bitch to make, helium tight welding is a tough thing to do

The youtube vidja I just watched said the welding was done with a laser.

Hopefully not attached to a shark.

The two ways I know to reliably produce helium tight bonds are indeed laser welding, or explosive welding. Both of which are cool as shit

Amazon Dash Button’s are wicked cheap on EBay.

I can turn them into HomeKit buttons easily.

Welp, mirroring is chugging along at 500MB/s.

I think my use case is pretty much satisfied.

 

[Jehannum]

The long and short of it is that HGST won't say exactly how they measure helium present, @Domon.

 

[gee]

There's a WD patent where you measure the helium concentration in a drive by pulsing energy into a thermistor and then measuring how quickly it cools back down. This measures the thermal conductivity of the gas in the drive, and you can determine the helium concentration from that. Clever and dirt cheap. I'm betting everyone else licensed that.

Pressurizing the drive and using a barometer works, unfortunately you can't use MEMS barometers in a helium atmosphere and non-MEMS ones are expensive.

Unless something has changed, that's super hacky. I just threw mine away.

The biggest complaint is the 3-10 second delay.

For some things I would be fine with that.

@Domon drives acquired.

Now I’m looking at another Synology NAS.

 

[Valve1138]

The single nic in the Plex/ryzen server decided to die.

No pci-e slots available.

Currently running with a usb 3 AC wireless adapter.

Meh.

if you have a usb c there are plenty of straightline usb-c to gigabit ethernet adapters that are pretty much as good as built in.

usb-c is an awesome standard

I have USB 3 and I ordered a GigE adaptor for it.

I also found a Synology DS418 Play on Amazon Warehouse
