Why are my 4K Writes half what they should be?

post #1 of 7
Thread Starter 
I have 2 RealSSD c300s in RAID 0 on SATA 2 one pic is the benchmark review of the drives and the other is my benchmark.

Before I put them in RAID 0 they both got the same score within margin of error.

The only thing I can think of is because the OS is running off of the drives but I don't see how that would mess up the writes so much.

Both drives where almost exactly what the same benchmark thread said a single c300 should do on SATA 2

Edit: did the test a few more times and got...

4K.................. 190.79, 190.36
4K-64Thrd....... 127.48, 107.45

All other results remain consistent.

Lmao, I just went through this yesterday myself. Got the crucial m4 256 and realized after 5 hours dicking around the x58 is not the best platform for SSD's. Still its fast as hell and only benchmarks show were getting screwed. Otherwise I'm happy. The newer 1155 boards will give u the speed were missing but its not worth upgrading for. I say be happy and stick with it until 5 years when its worth upgrading CPU, mobo, ram etc. Cheers.

Basically x58 and ssd = half 4k and sequential. To maximize speed on it. I used sadly the marvel 6gbs with 6gbs sata cable and achi setting in BIOS before u install windows 7 and Aldo running the ssd tweaker.

That figures, only thing I can really complain about with x58. SATA 3 ports are complete junk too lol.

Yeah but hooking my ssd to the marvel 6gbs increases my benchmarks a little so it's better than nothing regardless battlefield 3 comes out Tuesday and I'm excited as hell. Here comes ultra graphics for us bro )))

But you don't have TRIM support on the marvel chipset.

GC on the newer SSD's has been improved enough that you really do not need trim anymore. Just use the GC function on the SSD.
