my external hdd are all powered 12V 1.5amp switching power supply, maybe I should just plug in an old pc power supply I have lying around, hook up the 12vdc to a rail and make pig tails to power each hdd.

I'd love a backblaze, but damn they arn't cheap lol. Really what I'd love to see is an add-on card that has like 6+ SAS ports or like 24 sata ports without it breaking the bank. When I built my storage server I had to use a bunch of separate cards with 2 SAS ports and it took up all the PCI slots. (1 SAS converts to 4 sata with a breakout cable)

Might actually look at building out a custom backplane one of these days as I really like the backblaze design where the drives go from the top, more space efficient. Might even be able to buy Sata to pcie chips on digikey and the entire board could just connect to a PCIe slot via a riser cable. Could be a fun project. Actually even doing something that uses USB would be cool a sit would work with a Raspberry pi. The new one has a dedicated USB 3.0 port so it would be somewhat viable.

err, you can buy a BB pod with all the parts sans hdd and build it.
I doubt a RPI4 can push the iops you want.

They are still like several grand without the HDDs last time I checked. I'd only use USB for archive stuff or where speed does not matter. Basically I have a bunch of small drives, like 250GB and 400GB that could use a home. I have the SAN enclosures that house them, but they are super proprietary and you can't put your own drives in it, but the drives themselves are still standard desktop drives.(Maxtors oddly)

... chuck those drives and buy a 12TB my book

I already have the drives. Mostly I'd use them to experiment with different raid solutions like ZFS etc. Right now I'm using mdadm raid but I want to look into ZFS or gluster or ceph. Eventually want to look into a different VM solution too, probably Proxmox. Whenever I feel like spending the money I'll buy a couple off lease SFF PCs to build a small cluster as they go for cheap. Most will have a CPU that has VT-D so they should work fine for virtualization. Ram will tend to be low and hardly upgreadable but fine for a lab/test setup.

Of course I can just use the drives in their enclosures but I still like the idea of building a custom storage pod. As they die off I can replace with bigger drives. My mining rig case would make a decent start for a storage pod.



Never did end up finishing that rig lol. Bought molex crimper and everything so I can add custom wiring to fill it with GPUs and stuff.

oil pressure switch replaced on the odyssey. hopefuly that will enable cylinder disconnect again to save some gas.
