Any hard drive can fail at any time with or without warning. Worrying too much about individual drive families’ reliability isn’t worth it if you’re dealing with few drives. Worry instead about backups and recovery plans in case it does happen.

Bigger drives have significantly lower power usage per TB, and cost per TB is lowest around 12-16TB. Bigger drives also lets you fit more storage in a given box. Drives 12TB and up are all currently helium filled which run significantly cooler.

Two preferred options in the data hoarder communities are shucking (external drives are cheaper than internal, so remove the case) and buying refurb or grey market drives from vendors like Server Supply or Water Panther. In both cases, the savings are usually big enough that you can simply buy an extra drive to make up for any loss of warranty.

Under US$15/TB is typically a ‘good’ price.

For media serving and deep storage, HDDs are still fine and cheap. For general file storage, consider SSDs to improve IOPS.

I didn’t notice until now that your characters sometimes slightly cover the text boxes! Very cool.

Waze is of course owned by Google…

I expect they are talking about the ‘irrevocably’ part, as one of the core tenets of GDPR is that consent can be withdrawn.

I couldn’t say whether or not that applies here.

Secondhand stuff can be really cheap if you know where to look, but the drawbacks are usually power and noise.

Bear in mind many models also have voice recognition, and the Bluetooth can potentially pick up the MAC on every phone in the car.

Biggest question to me is why you need an IP in the first place?

Let me introduce you to ebm-pabst.

Plenty of modern rolling stock already has water cooled power electronics, oil-cooled transformers, and I’m sure there’s RGB passenger information displays.

They also laugh at your little 120/140/200mm fans.

That means no need to cool the hydrogen down, making it non-flammable and giving it a higher density than an ion-lithium battery.

Hot hydrogen burns just as well as cold hydrogen. Better, in fact.

How do you spot a greenwash vaporware startup? They promise the earth, use non-existent tech that, if it existed, would be better used in a dozen different places, and target it at residential customers with a subscription model, where the pricing is set before even the specifications.
