Needs some Advice.

post #1 of 2
Thread Starter 
Setup:
Board: Asus P7P55D-e
I7-870

I just bought 2 Agility 3 60gb SSD SATA III Drives:
I want to go with a Raid 0 Setup but found out the 6gb/s Sata III ports on the board do not support Raid.
For now I just used the Sata II 3gb/s ports with the raid 0 setup.

My questions are:
Would I be better off running the drives not in a raid setup on the SATA III ports or my current raid 0 setup or purchase a raid controller?
Would I notice much of a difference by purchasing a raid controller? I am looking at the rocketraid 2720.
However I would loose a PCI-e port on the board due to the fact my current setup has two video cards.
What is the best route to go here? spend the extra 200$ on a raid card or continue with what I have?

Thanks in advance.

corradokng, you seem to be in the same boat as many X58 owners - the only SATA III ports are Marvell based solutions. The Marvell ports are known for maxing out at approximately 350mb/s, instead of the actual SATA III maximum of 600mb/s. The Intel SATA II ports on your board are by design limited to only ~275mb/s sequential reads/writes. I have two identical SSDs to you, and they have the potential for 500mb/s.

My recommendation is to have them in RAID 0 on the Intel SATA II ports. The reason for this is twofold. First the Intel ports have less latency and in most cases faster 4K access (important in real world) than Marvell solutions. Additionally two SSDs on the Intel ports have the same approximate sequential read/write to a single drive on a real SATA III port, but is faster than one SSD for files larger than the stripe size (usually 64K or 128K) to the maximum SATA II throughput. The second reason is that it saves money, because the only thing you get if you fork out cash is sequential read/writes - that is if you regularly copy large files (say many DVDs). For regular use, it is unlikely to be noticed. However if you are a benchmark junkie, consider the LSI and IBM (cheaper LSI rebrands) PCIe products.
