I mean, with stuff like ZFS, it's a little hard to justify the outlay for all solid-state disk storage when I can build out a large storage array using HDD's and use one mid-size SSD for ZIL and then L2ARC to provide read/write speedups. Who actually cares what the underlying storage mechanism is as long as the dataset is backed up and the performance is good?

Power consumption, noise, durability...

There is a lot of power to waste for the savings you made, when not buying expensive SSDs (20€ a year is not much). Where we use HDDs, we don't care about noise. Durability? We use huge RAID systems with lots of redundancy.

I personally like to swap new drives after 5 years to avoid failures. So when you find a 16 TB SSD for 350€, you send me a message.

My 4 bay HDD NAS uses around 45W, 50W with some light load, 70W spinning up. That's about 1kWh per day, or 150 EUR per year.

I use it in my room, so I very much care about noise.

More durability = less redundancy (less cost) + less frequent swaps (less cost). My anecdotal evidence is 1 failed SSD in 15 years (160GB Intel, basically first Gen). Every other SSD is still working. I have a drawer full of failed HDDs.

Plus more performance.

Geez power is expensive for you folks.

In Vancouver we pay 0.14 CAD per kWh (.096 EUR) for usage beyond 675kWh in a month. (0.0975CAD, 0.068 EUR, before the threshold)

With the SSD's I can afford, there are what you might call "net negative savings" when I save maybe a couple dollars in power a month but have to replace them every few months. We can't all afford EVO's.

This is my thing. I have about 122TB of spinning metal (with the same as an offsite backup) with SSDs as ZIL and L2ARC. And it's awesome. HDDs I think will genuinely be important for for the foreseeable future.

As a newb I hope one day in my journey, I can look back at this and say "I finally understand this." Til then thank you, magic man

Don't let your dreams be dreams, I didn't know Jack shit about nas and just built my own with an old pc, I tried truenas but ended up paying for unraid, it was just easier for my needs.
