Then a HW Raid is preferable. Why? This is a Linux that more or less only does RAID and nothing else and the transfer speeds it reaches are really nice.

Because I do not know how to successfully restore a broken software array. I had to remake a software array in the past, and put the backups on the newly created array. With HW-RAID it was a piece of cake to rebuild a raid 5 with a 3Ware 4 port sata RAID running on the remaining 3 disks, rebuilding with a new 4th drive while the system was running normally. The rebuild was started with the HW-RAID's bios, allowing normal booting and server operation(albeit a little slowed down), during the rebuild. I do not trust a software raid from personal and the experience of (or reason given by) joakimsen@gmail.com - Tue, 7 Jun 2011 15:48:32 -0400
I used to use MD raid based on advice provided in the Linux community that it's "great" yet when the array (for no explainable reason... I use the same disks with a real hardware controller to this day) decided to break itself, there was no way, no possible command to force the array to be working again. The system wouldn't even boot up! Yet I could still mount the individual disks of the RAID-1 array, read the data and verify that both disks maintained data integrity. No Also, from
