If you buy one Raspberry Pi upgrade, make it this

The ability to swap operating systems on a whim is one of the best things about single-board computers like the Raspberry Pi. You can write a new operating system to a memory card whenever you fancy, and keep a small collection of cards handy whenever you want to change.

Is your SSD slowing down? Try this $8 fix before buying a new one

Times are tough for those of us who want to buy a new SSD. You don't have to aim for the fastest drives availableβ€”all SSDs are overpriced right now, and chances are that it'll only get worse. That makes it harder to replace or upgrade your existing drive, which is why it's time to get creative. This inexpensive gadget might be able to help if you're not happy with your current SSD, and even if you are, it can help it live longer.

Stop manually copying SD cards: Here is the automated NAS workflow

I do a lot of photography and videography, and those files can take up a lot of storage. I used to just store the footage and photos on my laptop’s internal storage, moving it to the NAS only when needed. Now, I just back up the footage to my NAS first and work from there, and that workflow is so much better. Here’s how I automatically back up my SD card to my NAS, and how you can too.

A Petabyte NAS Using Consumer-Grade Parts

Self-hosting a few services on one’s own hardware is a great way to wrest some control over your online presence while learning a lot about computers, software, and networking. A common entry point is using an old computer or Raspberry Pi to get something like a small NAS, DNS-level adblocker, or home automation service online, but the hobby can quickly snowball to server-grade hardware in huge racks. [Dennis] is well beyond this point, with a rack-mounted NAS already up and running. This build expands his existing NAS to one which can host a petabyte of storage out of consumer-grade components.

The main reason for building this without relying too much on server-grade gear is that servers are generally designed to run in their own purpose-built rooms away from humans, and as a result don’t generally take much consideration for how loud that environment becomes. [Dennis] is building a lot of the components from scratch for this build including the case, the backplanes for the drives, and a backplane tester. With backplanes installed it’s time to hook up all of the data connections thanks to a few SAS expanders which provide all of the SATA connections for the 45 drives.

There are two power supplies here as well, although unlike a server solution these aren’t redundant and each only serves half the drives. This does keep it running quieter, along with a series of Noctua fans that cool the rest of the rack. The build finishes off with an LED strip which provides a quick visual status check for each of the drives in the bay. With that it’s ready for drives and to be connected to the network. It’s a ton of wiring and soldering, and great if you don’t want to use noisy server hardware. And, if you don’t need this much space or power, we’ve seen some NAS builds that are a bit on the smaller side as well.
