An all SSD storage array would be quiet (no fans, no hard drive noises), compact, and use less electricity 24x7. Might even have a longer service life without any spinning drive replacements.
Could you calculate how much your current storage costs annually just in energy?
Very good points. I'll have to measure the energy usage of my Synology sometime to see what it's doing now.
Currently, the cost to replicate the storage I have now with SSDs would be over $4500 for just the drives. That's compared to $390 for the same in HDDs. I'm pretty sure it'll take quite a long time to spend $4110 in energy costs. SSD prices are going to have to come down by orders of magnitude.
FYI, here's the numbers I was using:
- my NAS has four drives of 3, 3, 3, and 4 TB
- I was using the cost of 3 4TB SSDs
- either way, I end up with 8TB of usable space
