The Areca 1231ML RAID controller will be handling the arrays for both the Intel / Kingston X25-M and RunCore Pro IV arrays. When it comes to capacity the RunCore setup has a distinct advantage over the Intel array, 256GB compared to Intel's 160GB. Things change once inside the OS, though; the Intel drives have a useable 160GB but the RunCore drives once formatted shrink to 240GB.
On the price front Intel has an advantage since they recently lowered the price on their X25-M Series and the RunCore Pro IV drives were just launched. The Intel array has an MSRP of 780 USD while the RunCore Pro IV is 960 USD.
