It seems weirdly difficult to find a good solution to attach HDDs to my pi. Best case would be for me a enclosure with small power supply, space for my pi, and at least 2 bays for HDDs, rather 4. All that for under 100€ of cause :D

I could not really find cheap hhd enclosures that connect via usb. Any recommendations? I don’t really want to use HDD toasters, they feel not permanent enough for a Nas. I could also not find sata to usb hats for the pi that are available right now

    Your raspberry pi doesn’t have sata or pcie support. Depending on your use case you may want something other than USB as USB is slow

      I have 2 HDDs with a speed of 180mb/s with a burst of 6gb/s according to the Seagate website. Usb3.0 has a data transfer rate of 5gbit/s

      So the usb connection will be the bottle neck, but 1. My network speed is not that fast and 2. 5gbit/s is still plenty I think?

        First of all, you will never achieve usb3 full theoretical speed. Its just not going to happen. Even if you could though you wouldn’t be able to get full speeds because your bandwidth is split between devices. You will be sharing the bus between plugged in devices along with on board hardware devices.

          A USB 3.2 gen 1 connection (5 Gb/s) is still plenty for multiple HDDs AND when you have no need for compute on the NAS the network Link is the relevant bottleneck which is half of the USB connection.

          Then USB 3.2 gen 2 (10 Gb/s) interfaces on HDD enclosures get more common every day which gives even more headroom with little more expenses.
