What i want to know is, how much disk capacity does the Adaptec 2610SA support ? Can I exchange the 250 gb disks for 500 or even 750 gb ones ? Is there an issue with the adapter bios ?

Performance will be better and rebuilds will be better. But I don't know what you mean by security. Do you mean reliability? If so, they both tolerate a single drive failure. However RAID-10 can tolerate more than one drive failure if each failure is in a different RAID-1 pair. And RAID-10 is more tolerant to bit errors during rebuild because there is less capacity involved in each rebuild. So with that definition, RAID-10 is more reliable than RAID-5. BTW, the only time you would choose to NOT use RAID-10 is if you wanted to tolerate two drive failures or errors during a rebuild. In that case you're only choice is RAID-6.

Or is the trade off the cost of the second drive, the chassis to hold it, and that you can only use the space of one physical drive? 1. Money not an object! 2. Chassis not an object! 3. Security and speed is the object! Thanks, God bless and great day, Gary Matthews Please make it simple… is the only reason one would not use 10 (0+1) over 5 the cost of the second drive?

Im setting up a home recording studio and my aim is to have, to begin with, 4 500gb sata drives. I want 2 sets of striped sets (2 1tb disks) but i also want them to mirror each other. Speed isnt a factor, i dont care how long this takes to access etc. The inclusive factors are capacity and reliability. Ive been looking at an Adaptec 2610SA with 6 ports as this gives the the option to expand as well. Please could you enlighten me as to which RAID set and adapter to go for.
