My old Seagate Dockstar is still running but my requirements to it changed over the last months. Where before it was used as a NAS and small download server before – added with some small web services – I now needed something better.
I recently upgraded my Internet connection to VDSL 100 (100 Mbit down, 40 Mbit up) which lets the small embedded systems explode in case of I/O (i.e. unzipping while downloading etc. – even with only flash memory). On the other side I’m recently doing some web development with CMS systems which I would like to use as it will be on the final deployment server (Apache/MySQL). Doing this on a single core 1200 Mhz ARM is no fun. Additionally I will do some TCP/IP stuff in C in one of my lectures this semester and Python REST Backends.
I tried some scenarios on my other embedded systems (as the requirement would be 24/7/365) like Raspberry Pi 2 and Odroid U3, but both weren’t really satisfying. As my plans for the future are a lot more x86 use cases I decided to finally take a small Atom based system.
So here’s the conclusion on the used hardware:
- HDD: HGST Travelstar EA 5K1000 1TB, SATA 6Gb/s (HTE541010A9E680/0J26223)
- SSD: Intel SSD X25-M Postville 80 GB 2.5″ SATA II
- RAM: Kingston ValueRAM SO-DIMM 8GB, DDR3L-1600, CL11 (KVR16LS11/8)
- Board: ASRock N3150-ITX (90-MXGZ10-A0UAYZ)
- Case fan: Fractal Design Silent R3 50mm (FD-FAN-SSR3-50)
- Case: Inter-Tech Mini ITX Q-6 schwarz, 60W extern, Mini-ITX (88881146)
It was sold to me as a cheap bundle so I simply couldn’t say no to it (without the good old Postville SSD – I found that one on my graveyard 🙂 ).
When the HDD is running I’m having ~13W power consumption in idle – when the HDD is in standby mode it drops to like ~12.1W. Thats still a lot more than any embedded System but referring to the possible power that is available i guess it is a good compromise at all.
The system can be used with only passive coolers as the case brings an external power supply and a PicoPSU with it. But as the summer is quite hot here recently (~35°C a day) I just added a small case fan which is really silent. I’m running debian 8 jessie on it as it will be a (hopefully haha) real stable system for the future.
