+====== Overview ======
-{{:en:acc:cs2:cs_helios.jpg?600|}}
+This wiki page shows cloudshell2 performance.
+RAID0, RAID1, SPAN, and PM mode separately thereby set the mode switch on the cloudshell2 board
+and added a test condition installed software RAID mdadm in the JBOD(PM) to compare with hardware RAID and software RAID.
+====== Test environment ======
+** Hardware **
+  * [[http://www.hardkernel.com/main/products/prdt_info.php?g_code=G149142327280|CloudShell2]]
+  * 3.5" 4TB WD Red NAS HDD x 2
+** Software **
+  * Ubuntu ( Kernel : Linux odroid 4.9.28-38 ) : Samba, dd(data dump) command
+  * HELIOS LanTest utility
+  * Software setting followed by [[http://odroid.com/dokuwiki/doku.php?id=en:xu4_cloudshell2:software_settings|here]]
+====== Test Result ======
+ **Watch this result out, HELIOS LanTest shows RAID 0 mode is the similar performance with RAID 0 of HW or SW. However, \\
+In general, the result shows that <color #ed1c24>hardware RAID is about more than 10% faster than software RAID mdadm</color>.**
