With the current pricing landscape, I call it a draw. Unless you have a Raspberry Pi 4 laying around both NAS solutions come at a similar price and offer enough to get you interested. So the only question is: do you trust your skills and take the slightly higher hardware specification of the Raspberry Pi 4 board, or would you rather get a consumer box from Synology, and enjoy the ease of use and broader storage support? Let me know in this Reddit thread as I’m curious to hear your thoughts. Install the Raspberry Pi 4B after fixing the spacers on this side, and place the 7-pin cable between the two I think the Compute Module 4, with it's built-in Gigabit networking and ability to use one or more PCI Express cards, is the first Raspberry Pi that I would consider 'good' for running a reliable and performant NAS.

Then run and replace MyExternalDrive with whatever you want to name your drive: Love your articles and videos! Something to think about next time...try using the BTRFS filesystem instead of mdadm. I abandoned md based raid over 10 years ago already and have been using BTRFS with great success on all my production servers in various raid configurations. BTRFS makes managing discs and filesystems and raid a pleasure. It is so incredibly easy to add new drives and dynamically expand your raid array while it's running. You can even change raid levels while the array is online. BTRFS also supports on the fly compression, which makes your storage go a little bit further than normal. Don't listen to the naysayers who say BTRFS is not production ready and not stable, that's a myth. I've never had data loss in over 10 years due to BTRFS, in fact it's saved my bacon more often than I can count. Major linux distros like RedHat and Suse are making it their default file system for a reason. I'd be really curious to see benchmarks on the hardware you're using with BTRFS compared to the conventional md raid array you used. Keep up the great work!

IoT – Internet of Things

Now it's time to share that drive on your network, so you can add your files and access them from any device in the house. To do this, we need a tool called Samba, which is an open-source implementation of Windows' SMB/CIFS file-sharing protocol. These cover all the software needed for our NAS project, but they are not enough for a complete NAS system. We also need a preferred case, otherwise, the Raspberry Pi NAS will only run bare metal. Although there are many cases available in the market for Raspberry Pi 4B, as a NAS system we need a case kit that can accommodate at least 1-2 internal SSD/HDD and must also have a good heat dissipation design.

When you run that code, it will open up a wizard called Parted, which will allow you to create a new partition on the drive. Run this command, pressing Enter after each answer in the wizard and replacing MyExternalDrive with the name you want to use for the drive: While the hard drive does put through decent synchronous numbers (it has more bandwidth available over PCIe than the microSD card gets), it gets obliterated by the itsy-bitsy microSD card on random IO! The SilverStone Pi02 is a case for those that wish to use their Raspberry Pi 4 as a desktop computer or as a server. It provides great cooling and while it may not look fancy, it does have a robust, industrial look to it. While primarily designed for home environments or small home offices, OMV's use is not limited to those scenarios. The system is built on a modular design. It can be easily extended with available plugins right after the installation of the base system. OMV is the NAS server system software we are looking for.To offer you at least something, we have decided to open-source all the design files that we created so far. You will find them soon on GitHub under the following link: At this point, we have four independent disks, each with one partition spanning the whole volume. Using Linux's Multiple Device admin tool ( mdadm), we can put these drives together in any common RAID arrangement. You may also want to watch the progress and status of your RAID array while it is being initialized or at any given time, and there are two things you should monitor: If you are looking for a passively cooled case for your Raspberry Pi powered home server, then SilverStone’s PI02 should be on your shopping list. This all aluminum case comes in two pieces which slot on top of one another. Inside the lower piece are four raised screw points used to secure the Raspberry Pi 4 to the case and prevent the Pi from slipping and shorting. One other thing I had to do a number of times during my testing was delete and re-create the array, which is not too difficult: # Unmount the array.
