install ownCloud on a NAS

I want to install ownCloud on my NAS Server Synology ds415+ to share files, at first we download the install files from here.Then upload this file to your NAS and open it in the Browser if you got an permission error look at disk station manager synology – change web rights.Then follow the instructions and if you only have to run this service on your server you cloud install it in the current folder with a dot.And I prefer to use as database mariaDB over liteSQL.

And now we are done:

NAS Server Synology ds415+

I searched a long time for the right NAS, because it should need some things that important for me :

  1. Terminal SSH
  2. DNLA
  3. 4 HDDs with 4TB
  4. apache
  5. very fast connection
  6. encryption

And I choosed the ds415+ for 513€ because it seems the best solution for me.Because its have a very fast XOR(for RAID5) and AES(for encryption) performance, is based on Linux Kernel and seems one of the best NAS Systems on the market.After some days I got it and here it is:


  • INTEL Atom C2538(4×2.4GHz)
  • 2 GB DDR31600 CL11
  • 4GB internal store


2015-03-16 17.09.51 2015-03-16 17.10.122015-03-16 17.09.07 2015-03-16 17.11.392015-03-16 17.11.57


Then I upgraded the RAM with a “Kingston 8GB DDR3 1600MHz Non-ECC CL11 SODIMM” for 70€, that is not really necessary but I need a big cache for my database.This is the ram usage just with some apps running:

Hard disk

I created a RAID5 with 4 WD40EFRX.One of them cost about 170€ that’s not cheap but for 4TB at this good quality it is okay.I chose the RAID5 over RAID10 because so i get the size of 3 disks and not only 2, the performance is more than the network can handle.

Here we see that volume1 has a size about 10.8T that’s very much space.

Here we get a little Benchmark about the Hard disk, we see reading is more than enough, and the most of the time i read from the disk.

For more Information about Benchmarks see Benchmark Your System.

This is the Writing, we could see the network is the bottle neck, I use only one LAN Port because my main board cant handle I moved a file via FTP to my NAS its only writing:

Its about 75MB/s what’s a good value is for a RAID5.



I have the problem that every connect to my homepage lets my HDDs spin up, so I tried to mount a USB into the File system to host my Page and MySQL on it.

At first we need a USB stick and change the File system, make 2 Partitions.One of them for the database one for the Web page, I choose 1/3 to 2/3 of the Stick size.And its better if the USB supports USB 3.0, now we connect to our NAS via SSH and look what’s the name of our Stick:

Before we make some changes shut down your word press, phpmyadmin and database !

Okay now we copy our web and mysql folder to our USB stick.Importand is to only move the mysql database and not the postgress because the postgress is needed in the start-up and your NAS would crash.

Now we make a copy about our Directory’s, if it crash we could move it back.

Okay now we need a folder to mount our new files from the stick.

Now we could mount the Stick, its important to mount it after every reboot.

Now we could turn on our web services.If you use phpmyadmin and MariaDB it could be useful to take a look at phpMyAdmin and Mysql Cache tuning.



If you have it in a room where you work its no problem, if its completely silent you can hear it a little bit.I turned it on silent mode.



The Power usage is between 12W and 40W.

working 30-50W
 start up 38W
 waiting  32W
 sleeping  20W



All together its a very good NAS and I would buy it again.But if you look at a cheap solution for backup and web space look at Silent PC for 260€ it also need less power.

Silent PC for 260€

I build my own silent PC, and I mean realy silent so no fan no HDDs.The Price is about 260€(without chassis) and really cheap for a silent PC with this specs:

CPU  4x2GHz
 SSD  64GB

I used it for hosting hompages and as NAS.

I chooses this components:


Mainboard – ASRock Q1900DC-ITX

MainboardCPU: Intel Celeron J1900, 4x 2.00GHz, 2MB Cache, 10W TDP •
RAM: 2x DDR3 SO-DIMM, dual PC3L-10667S/DDR3L-1333, max. 16GB (UDIMM) •
1x VGA, 1x DVI-D, 1x HDMI 1.4, 2x USB 3.0 (J1900), 2x USB 2.0, 1x Gb LAN (Realtek RTL8111GR), 6x Klinke
2x SATA 6Gb/s (ASM1061), 2x SATA 3Gb/s, 1x CPU-Fan 3-Pin, 1x Fan 3-Pin, Audio: 7.1 (Realtek ALC892) • RAID-Level: N/A • Multi-GPU: N/A
Grafik: Intel HD Graphics (IGP)
Power: 1x DC-Stecker (9-19V)
Mini-ITX, UEFI, All solid capacitors, passiv cooling

Price: 100€


RAM – Kingston KVR13S9S8/4

Ram4GB (1333MHz, 204-pin, CL9) DDR3-RAM

Price per 4GB :35€ (I choose 2)


SSD – SanDisk SDSSDP-064G-G25

ssd64GB SATA III 2.5 Zoll
Read:490 MB/s
Write:240 MB/s



Power – Vanson SMP-70W

Power0 Power1

Input Voltage: AC 100 – 240 V
Frequency: 50/60 Hz
Output Voltage: 15 / 16 / 18 / 19 / 20 / 22 / 24 V




Its absolutely not hearable but you can add some silent fans to cool it down a bit for the summer, so it comes about 40°C, better take a look at CPU Temperature.



The Power usage is 12-15W.



All together its a real nice PC for small projects but for a NAS its not really nice because of the I/O.If you look for a NAS look at NAS Server Synology ds415+.
