  • “The cause is a new SATA specification which includes the ability to disable power to the hard disk. When you look at the SATA power connection on the back of your hard drive, there are 15 pins that make contact with your power supply. It’s the third pin that delivers a 3.3V signal that disables the drive. What we need to do is prevent that third pin from making contact with the power cable.”

    Some hotswap harddrive bays use this feature, definitely more common in enterprise scenarios or in USB HDD enclosures.


  • I’ve always liked the ultrastar line. Used to be made by HGST and then WD bought them. I’m using specifically the HC530 14tb. The line has a long history of being very reliable enterprise drives.

    I’ve bought mine from both goharddrive and serverpartsdeals. Both are reliable resellers of used storage. They’ll warranty the drives for 2 or 5 years depending on which you to with. Prices are ~$130-$150.

    Be aware you might need to do the electrical tape over some of the power pins hacks depending on your setup.

    Ps. One of the listings for the HC530 on goharddrive or serverpartdeals is incorrectly labels as HC520. Just pay close attention.


    As far as raid goes, Raid 10 is currently very popular for its speed and drive failure tolerance. Remember, raid is not a replacement for the 3-2-1 backup rule. Raid has some fault tolerances for bad hard drives, but doesn’t protect against a failed raid card, fire, flood, robber, acts of god, etc.

    You can also look into zfs and truenas if you feel inclined. Be aware that if you go with this setup, ecc ram is basically a requirement



  • Love my 11th gen framework, but there is an issue with the 11th gens where the CMOS battery will die rather quickly. If it does die then the laptop needs to be plugged in to turn on, even if it is fully charged. Framework is aware of the issue and will send a free replacement battery or, if you can solder, a mod that will eliminate the issue for good.

    Still love framework and would definitely recommend them - but the 11th gen line (their first product) has a few gotchas




  • I’ll start this by saying I’m not familiar with either model, but as a general rule, always go x86 when you can. The Intel processor is going to be much better supported. You might get the snapdragon version to run, but it likely isn’t supported by mainline Linux.

    That being said, touch screen support on Linux is improving rapidly, but still isn’t quite there. Make sure you’re aware of the user experience before buying so you won’t be disappointed.

    Also, my unsolicited 2 cents, I would try to avoid buying lenovo. I’ve had the unfortunate responsibility of fixing a few of their products (an all-in-one and a few laptops, including a new thinkpad) and can confidently say their reliability, and repairability have greatly diminished. They use cheap parts and are in general, poorly designed.

    Onshape hands down. Browser based so there’s no compatibility issues. It’s super easy to use and pretty powerful. Its free for hobbiests (the caveat being your models will be publically accessible). We use it exclusively at work and it’s been awesome.

    I’d love a good Foss CAD package but there are too many issues with the current ones for me to make the jump.




  • Ah ok. I’ve done opnsense and pfsense both virtualized in proxmox and on bare metal. I’ve done the setup both at two work places now and at home. I vastly prefer bare metal. Managing it in a VM is a pain. The nic pass through is fine, but it complicates configuration and troubleshooting. If you’re not getting the speeds you want then there’s now two systems to troubleshoot instead of one. Additionally, now you need to worry about keeping your hypervisor up and running in addition to the firewall. This makes updates and other maintance more difficult. Hypervisors do provide snapshots, but opnsense is easy enough to back up that it’s not really a compelling argument.

    My two cents is get the right equipment for the firewall and run bare metal. Having more CPU is great if you want to do intrusion detection, DNS filtering, vpns, etc. on the firewall. Don’t feel like you need to hypervisor everything
