Configuring Network Folder Sharing On Radxa Rock

Radxa Rock - the cheap and powerful quad-core mini-computer has already receiving great success with majority of stock vanishing across all major online distributors. Luckily, I had received my Radxa Rock a while back and has now successfully taken over the job of my Wireless Network Attached Storage (NAS) from Raspberry Pi.

The process of setting up NAS on Radxa Rock is much more easier then Raspberry Pi as the external disk is automatically detected and mounted on every boot (Thanks to Ubuntu Desktop based Linaro image), but when using the folder sharing via Samba Share we need to add an extra line to smb.conf to make the data accessible over network.

Hdparm - Command Line Performance Tuning And Benchmarking Tool For SATA/IDE Hard-Disk Drives

hdparm is a powerful command-line utility for Linux and Windows operating systems to set and view ATA hard disk drive hardware parameters. The utility also allows users to test disk read/write performance with cached and buffered modes. The utility allows users to view and change SATA/IDE disk-drive hardware parameters like drive caches, sleep mode, power management, acoustic management, and DMA settings which are generally set to suboptimal conservative defaults to their optimal settings for best performance. Checkout the example output below for disk information command followed by disk performance test.

How To Mount DD Disk Images With Read/Write Support On Windows

When it comes to perfect backup's, RAW disk-images are the choice for safest form of backup and restoration of fully functional operating-system installations. We have shared two methods of using the same to backup Raspberry Pi SD Card from Windows as well as Hot Backup's from RPi itself using Linux DD disk imaging utility. Once created we can also Mount these backup images with full read-write access for various tasks like Data recovery (For example imaging an corrupted disk and accessing the disk-image from another working computer to recover data).

OSFMount is a free Windows utility which allows you to do that, the software enables users to mount local disk image files in Windows with a drive letter which can be accessed like any other partition. The images can be mounted in read-only mode as well as write-enabled mode, OSFMount also supports creation of RAM disks (See What are RAM Disks and How they can be used to make use of non-addressable wasted RAM on Windows) which offers a huge speed boost over using disk-based images.

How To Measure Download/Upload Speed From Linux Command Line

speedtest resultThere are numerous web-services like Speedtest.net which allow users to simply open a web-browser and benchmark their internet connections upload and download throughput with ease. However, if you need something similar for your server which does not have an graphical interface here are a few options to check network throughput from terminal/console. One can simply check download speed by using something like the command below at the terminal,

wget --output-document=/dev/null http://speedtest.wdc01.softlayer.com/downloads/test500.zip

But for a thorough check with option for outputting beautiful shareable badge like the one on the right, we will use the "Speedtest" command-line utility as shown below.
