Finalizing my Chia Setup

  • How big are your SAS drives?
  • How much power they draw when active?

You can jumper the supply to come on and power the drives. When your server boots the drives should be ready.

Why did you pick 16tb disks?

His picture shows 500gb disks.

They are Seagate 6tb SAS, idle they say around 7.5w draw

Getting around .15 cent CAD per Kw atm

500 GB Disk will run in RAID 10 for Plotting, Don’t need insane speed just something to keep filling my drive daily

Drives are not 16 TB, Just the image I used as an example for the setup

Just giving you the feedback from your picture like you wanted.

At this moment, I’m looking to buy only 18TB disks. And the space to hold them.

Would only need 6 of these racks

Wow that’s a pretty sweet price to get a 300TB farm, good deal on those drives.
Power consumption will be a bit higher of course relative to using bigger disks but at 15 cents and such low purchase price you’re pretty ok.

Plotting will be pretty slow though, gonna take many months to fill up 300 TB.

Out of curiosity, what power supply is that? how much Amps can it take on the 5V rail?

I was looking into these to hold my drives, With my current setup Idea I would need like 7 of these, costing me around 140 USD… I could probably design something similar to print but they are pretty filament heavy, I’m sure around 2 dollar of filament per Mount. The guy selling these is making some good money off us Chia Miners lol

But an amazon wire rack and some filament to print my own mounts cost me around 65 USD, 3D Printer was already available so I will not count the cost of the Printer. Mounts are around .06 Cent a piece in filament. 3D Printers are truly Amazing and have saved me Hundreds if not thousands over the years!

This is what I don’t understand, Power supply and how much each SATA power can deliver, I’m scared that I will over do it and Burn out the PSU. I have a terrible understanding when it come to Electrical. Would you be able to link a PSU which is a good option for my Setup?

Just another way

Oh this is pretty cool, I will look into these, I will cancel my order on 1x4 SATA Power Cables and extra PSU for now and calculate pricing on these

Okay After Calculating
Edit: Thought it was 4 driver per cable, turns out its 5! and math was off but fixed now…

99 USD for ChiX +750w + 4 Cables (20 Drives)
30 USD for 6 more cables (30 Drives)
129 USD to connect 50 Drives is Great

Pervious Setup cost $140 CAD For the PSU and $50 CAD for the Cables totaling 190 CAD, Your recommendation save me around 30 bucks and will look a lot cleaner :smiley:

That’s good, think that’s the better solution. Also because as far as I can see the Inwin p85 only has 5 sata power ports on it, not 12 as you mentioned

All you need to know is already described in this mega thread: Scalable DIY SATA JBOD - Will store over 250 Disks!

Just get 512 GB RAM.

Forget 16 TB HDDs, get 18 TB Drives. Saves you money for cables, HBA etc.

just like every thing add money and stir… :money_mouth_face: :money_mouth_face: :money_mouth_face:
