Raspberry Pi Hard Drive Enclosure

Post by Dave » Thu Nov 05, 2015 5:29 pm

We've had a few requests for a hard drive + raspberry pi enclosure. One that is a contained box, and not just a layer of acrylic.

So I got to the drawing board and have come up with this first version.

It has mounting holes for both 3.5" drives and 2.5" drives.

Will also contain a SATA -> USB converter (fully tested on the latest Raspberry Pi 2 Model B on the latest Debian, Jessie)

(The acrylic has its protective film on still, hence the blue tint)

Thoughts and opinions?

Do I need to add some cut outs to act as vents? Do we want access to the GPIO from outside the case?

EDIT: Think I'm going to increase the hight of the case slightly, to allow space for low-profile HATs to be fitted... Specifically our UPSPico - http://www.modmypi.com/raspberry-pi/bre ... /ups-pico/

Add extra fixing holes to the Lid so that people could easily attach extra boards if desired?

Any potential for knockouts around the rest of the edge (so we could add other output ports as needed)?

Just a quick update...

We have had various comments saying the case is too big. So we are looking into ditching the powered SATA -> USB converter and just using the basic cable versions that are available.

This will mean we can reduce the footprint of the case, but it will mean only 2.5" drives will be compatible!

Do you have any examples of things you would like to mount on top? So i can look into putting mounting holes in the correct place.

I could put in a generic knockout section for GPIO access, or a simple slot to allow a ribbon cable to be installed.

Well I've been toying with the idea of having an A+ Pi Drive, I bought a 2.5" 1TB drive awhile back and got an ENC28J60 SPI based ethernet breakout board. I'm not sure what Else I would add into the case, maybe a set of 433MHZ transmitter and receiver.

Hi,
Just to throw my thoughts in! And its great by the way! I've previously contacted you about one of these! I'm so glad you're looking into selling one!

Like most people asking for it, i guess the idea is to build a small low powered nas box.
So a 2.5inch drive is a perfect fit for the job, the pico ups idea is a nice little touch!
Would the power go into that board or the main pi??? Holes would be needed for the pico board if that was the case!
Also a knockout for the fan kit and space for the extended battery would be a great advantage to!

Other than that I would suggest to keep it small and simple,

Thanks for doing this, let me know when I can buy one!

Pete

Taking on-board peoples comments, mainly the size issue, I have had a re-think and come up with this:

So as you can see, the overall size has bee reduced. Height is slightly taller, allowing space for Pico UPS and larger battery.

Punch out panel to allow a ribbon cable access to the GPIO.

This will support both SATA and IDE hard drives.

Power to the SATA to USB converter is optional... Depending on how power hungry your hard drive is. I was able to run this Jujitsu drive without additional power, but I do have the USB ports power boosted using the max_usb_current = 1 setting.

SD Card access could be an issue, but a quick thought would be to cut out a hole on the underside of the case where the SD card slot is on the Pi, just big enough to get a finger in. Probably wont be easy to remove/add a sd card, but it'll be easier than having to disassemble the case each time.

You can ignore the screws sticking up out the top of the case... Don't have the correct length screws laying around :)

Hi,
somebody from the support pointed me to that forum topic. The last post is quite old, so could you please give a short status report about the current state and plans.

I was looking for a case for the Pi2 and a 2.5" SATA-HDD from my old netbook.

My suggestions to your great design:
  • I also prefere a 2.5" case. I think using a 3.5" HDD is extrem exotic. Even using a 2.5" is a bit exotic.
  • Personaly I have no need for a integrated SATA -> USB converter. The point is that the Pi2 doesn't have a "internal" USB-connector. So I have to use a cable (from the HDD to the outside USB-Port) outside of the case. For that I would use a minimalistic SATA-to-USB-adapter
  • Very important is, that I can connect the case to a VESA-mount/adapter.
What do you think about seperating the HDD-case? Do you see a way to create a HDD-case that can be connected to an existing Pi-case? Maybe on the screw hols where a VESA-mount would be connected?

I am also interested in the Stackable Pi-cases and thought about if it wouldn't be possible to attache a 2.5" in there?

What do you think?
