After so much research I decided to purchase Adaptec AAR 2610 SATA RAID controller from eBAY. This supports 6 SATA drives on RAID 0,1,10,5 configurations. My original intention was to build RAID 10 array, which gives good performance and security at the expense of half of total capacity, meaning 6x500GB will give 1.5TB of total storage capacity with fault tolerance on one drive failure.However, since now I have only 5 bays, using raid 10 is not possible (requires even number of drives. Either I will have to use 4x1TB on Raid 10 or 5x500GB on Raid 5. Later option gives 2TB space with one drive failure protection but at small performance degradation.  Maintaining parity requires additional reads and writes which tends to slows down the array quite significantly if the harddrive access is dense. In my situation, this will not be a major issue, so it will not affect.<img src="http://www.elakiri.com/forum/attachment.php?attachmentid=12802&stc=1&d=1262245451" alt="" class="fr-fic fr-dii fr-draggable " style="" />This card is not officially supported by Adaptec, since it is an OEM product for DEL and HP. With some effort I manage to find the manual at DEL site, so it is not much of a problem.Most interestingly, this card is known to work with FreeNAS, the OS I am going to use (details later), so fingers crossed till I get my hands on the package.[FONT=&quot]Adaptec AAR 2610 – Rs. 10,000[/FONT]</blockquote>
