Best raid controller

Last response: in Storage

Hi all,
I just put together my extreme enthusiast computer! I had a question about raid controllers since Ive heard that dedicated ones preform much better than motherboard ones.
I want to know regardless of price, what the best RAID controller is? I will be using RAID 10 with samsung 840 pro ssds(512 gbs each). Also, I will have another 2 velociraptor 1 tb drives as storage drives. Can I set those in raid 0 separate from the RAID 10 setup? Would it be better if I bought a third velociraptor and used RAID 5 as my storage?

Also, Im not familiar with SATA Hot swap. Is the rIVe compatible with it(im pretty sure it is)? Would it be better for a dedicated hot swap controller to maintain it? Im pretty sure the mobo has a controller but I want to be sure since my case(the RV02e) has a dedicated external hot swap bay.

Best RAID controller to add an extra 'e' to your extreme rig would be "Nytro MegaRAID NMR 8120-4i". That should definitely give you bragging rights on build cost.

RAID controller primarily excel at parity calculation, which is not required for RAID1+0. RAID5 would definitely benefit, however RAID5 should not be considered for performance. You may see some inflated performance boost regardless of RAID level due to the onboard cache on a decent RAID controller, but that boost will not be of much benefit on a desktop, no matter how extreme.

haha nice....7000 dollars is an expensive controller!(not as in its something I wont look at, but I doubt i need it at all) but its an option. Its not so much the cost as in what the point would be.
3 questions
1. Whats the difference between the nytro and this one http://www.areca.com.tw/products/1882.htm (the ix-24)
2. whats the major difference between the ix 24 and lets say the ix 16 or ix 12
3. Would I see any difference in performance between the nytro and the ix 24 if the extent of the RAID unit would be 4 SSD RAID 10; 512gb samsung 840 pro AND 3 HDD RAID 5; 1tb Velociraptor
