device. But software RAID 1 or 1+0 on a modern Linux system of any type should be fine in my opinion. If you do go with HW RAID, keep in mind you also want a card that interfaces well with Linux not just for the drive contorller itself, but also the management interface for detecting failed drives, rebuilding arrays, etc. This is of course much easier with Linux software raid.
What about the I/O throughput? Software RAID has to write everything twice over the system bus while a hardware RAID can do the same with half the bus traffic. One of the reasons my colleagues were convinced to move away from Windows was that these files (smaller disks) are held on a Windows-implemented software RAID and are too loaded to handle the traffic. I have a hunch that Linux software RAID will do better than Windows but still it will have twice as much traffic as a hardware RAID, wouldn't it?
