Hi, I have a couple Corsair 60 GB Force Series SSDs advertised as "maximum read speed of 285MB/s and write speed of 275MB/s
I am running a Gigabyte GA-X58A-UD3R with OSX, My system is primarily a Visual Effects Compositing workstation and I am trying to find the best solution to run these drives in a RAID 0.
The options I have tried are:
1) RAID-ing them in the bios on the motherboard's Marvell 9128 controller. This produces an underwhelming xbench:
sequential:
Uncached Write 249.11 MB/sec [4K blocks]
Uncached Write 195.98 MB/sec [256K blocks]
Uncached Read 25.53 MB/sec [4K blocks]
Uncached Read 288.08 MB/sec [256K blocks]
random:
Uncached Write 64.09 MB/sec [4K blocks]
Uncached Write 213.90 MB/sec [256K blocks]
Uncached Read 20.16 MB/sec [4K blocks]
Uncached Read 268.00 MB/sec [256K blocks]
2) OSX can't utilize the ICH10R's RAID features
3) I am currently running an OSX software RAID 0 with better results than the Marvell:
Sequential:
Uncached Write 255.58 MB/sec [4K blocks]
Uncached Write 254.96 MB/sec [256K blocks]
Uncached Read 39.29 MB/sec [4K blocks]
Uncached Read 363.23 MB/sec [256K blocks]
Random:
Uncached Write 242.67 MB/sec [4K blocks]
Uncached Write 252.85 MB/sec [256K blocks]
Uncached Read 28.24 MB/sec [4K blocks]
Uncached Read 334.04 MB/sec [256K blocks]
I have 2 main questions:
1) With my current OSX software RAID configuration, should I be concerned about any significant CPU performance loss considering it is a software RAID? (I need all the performance I can get)
1) Would I see a significant increase in the performance of my RAID if I were to purchase a sub $200 Raid controller?
Thanks!
