Corsair Performance Pro 128GB RAID0 Benchmark and Review

Hey guys, just recently installed two 128GB Performance Pros in RAID0. Here are the benchmarks.

Overall, the system is running very smooth. No freezes, crashes, BSOD, etc.

Results look good. I'm looking at one of these at the moment, can I ask what marvell drivers you are using for the motherboard, I've got a gigabyte board with 6gb marvell 9128 and their still listing drivers from last year!

 

I actually have the marvell controller disabled. Running only on the Intel.

 

@FoLmEr: I'll look into that, but I thought it had to be updated together with the BIOS from ASUS.

for what it's worth, I can tell your as-ssd numbers were inflated by write cache. it's not possible to do 316mb/s on 4k write with a modern ssd.

 

these are some good numbers, but I wish corsair would have released a 64gb version of these drives. I raid, but I would rather raid 4x 64gb drives than 2x 128gb drives.

How's it not possible to get that high a write speed?

 

4x 64GB.. Doubling the chance of failure - you're a brave man :) Not to mention you'd have to invest in an add-in RAID card if you're not feeling well about having 2x 6Gb/s ports paired with 2x 3Gb/s ports, like the newest Intel mobo's offer. Even their X79 chipset won't have more than 2x 6Gb/s native Intel ports, which is sort of disappointing to me.

Yes I do have write cache enabled, and the SSDs themselves have 512MB DRAM cache each. So while the speeds are inflated by caching, it does not make them any less real. If you look at the Anvil benchmark it wrote 640MB of data in 4K chunks, and did it at 291MB/s. (I reran the test to write 4GB instead of 640MB and the result was 347MB/s.)

 

As far as 4x64GB, I definitely would not do that myself. Not only are you risking your data, it would not be cost effective. Although this does depend on your workload. If you do a lot of HD video editing, a 4x RAID0 + a $500 controller card might be worth your while.

rollerbldes, Nice results, I've been testing two SSDs in RAID 0 recently, so interesting to see the numbers. May I ask what stripe size you used?

 

IMO, what is so incredible is the reduction in the single thread 4k reads in RAID 0! I imagine that result is lower than a single drive of yours is, my results certainly are like that. Enabling write caching was a double-edged sword, increased some things and lowered others.

 

I believe what gjs is saying is that write caching enabled the result you have, just as RAID enabled you to get your results, which is true, and regardless the results are real.

 

Regarding the "old" Option ROM, yes the version number does not match the latest IRST numbers, if that is even relevant. But rollerbldes mother board, a P67, is hardly old, and ASUS is using that O'ROM on that board. Actually, an ASUS X58 board I have has the same version O'ROM. I don't know if you can get the latest IRST O'ROM from Intel, or somehow install it if you could. The only difference might be for Z68 boards SRT configuration.

 

I wonder what the results of four SSDs in RAID 0, two on SATA 6Gb/s ports, and two on SATA 3Gb/s ports would be? Would the performance be dragged down to SATA 3Gb/s levels in general? I would think so.

 

And X79 boards having only two 6Gb/s ports is very disappointing to me!

 

Marvell chipsets don't count, as they are not 6Gb/s interfaces, period.

Sorry I have been away for the past few days.

 

My stripe size is 128K with default 4K NTFS chunks.

 

Now that I think about it, I believe what is happening is that the random writes are being filled to the cache at very fast speeds then written to the actual NAND in a sequential fashion by the controller. This is a very smart way to increase the random writes if you have enough cache.

 

I think if you use 4 drives with two on the 3G ports, your performance will be the same or slowed on sequential writes and probably faster on random.

 

But yeah, hopefully next year the boards will have all 6G or something faster. SATA is definitely becoming a bottleneck. Imagine what it would be like to have SSD slots like RAM slots. Your northbridge or the CPU will be the SSD controller!:eek:

I can at least help you with 3 Corsair Performance Pro 128 GB at LSI 9265.

Cache is completely deactivated for the tests.
