Hardware RAID vs Software?

Better software, or to place a hardware controller. Trust the RAID on the motherboard is not worth it.

For low-end systems to better use the software. As written KerLaeda normal hardware RAID is expensive. Reliability as fake RAID is questionable. Using md on two servers more than year — flight normal. Judging by the manuals recovery for this is quite simple and predictable.

In motherboards usually cost fake-raid, knows how to distribute the data. If you will be covered with a motherboard or system restore may be problematic. I would choose the software. Besides not the fact that the built-in RAID frya recognize.

from the point of view of reliability — Yes, better external hardware RAID controller from any known vendor. but better to take a couple — so if one dies, be able to raise the array and not wait until you arrive replacement. Programmniy in this respect more flexible, the screws can always put in another machine and build it there.
from the performance point of view — the difference is usually invisible — the modern processors are pretty fast I think.
another argument in favor of hardware — if one of the screws dies, then the hardware he's usually calm vylivaetsya from the array. but the software the options are I had a case where one screw from the burnt electronics has introduced the core in such a reverie that I had to extinguish the machine. ie hot swap hardware is much better (if the controller supports and the basket is)

Normal RAID controllers start with the price of 10K. RUB that all previously — preprogramme deficiencies, which every couple of months will lay down you an array. Built-in motherboard controllers are the same, no reliability. So seriously consider if you only want speed at the expense of reliability that can be built on the embedded controller, if you need more reliable — think, and whether the winning rate is 10-20 thousand. rubles for the controller in your case? Because you can over that amount to take and high-speed HDD like a Raptor and a normal SSD.

Of course, hardware. Iron is always better performance/reliability than software.

Lord, still the best solution 100% is to buy a separate (not sewn into the motherboard) RAID a?
