Ridiculously slow 64-thread write for OCZ vertex 3?

[jihe]

I just replaced my samsung 830 in my HTPC (foxconn NTA3700) with a 120Gb Vertex 3, and I am getting this very strange result. When I test the drive with crystaldiskmark or ASSSDbenchmark, the multithread write would be so slow that I have to stop the test, and then it still takes several minutes for the system to recover from the freeze. Every other benchmark seems ok, 64-thread read is ok, 64-thread write would start around 50mb/s and the quickly drop to something ridiculous like 0.05 mb/s and system would freeze as a result. Is this a driver or firmware problem? Vertex 3 firmware is 2.15, driver is storachi, and offset is 359424k in ASSSDbenchmark. And I actually can feel that system is not as snappy as the samsung. I used macrium reflect to cloned the drives, could this be the problem?

i put one of those corsair v4's in a laptop and i didnt think it was much faster then the hdd it replaced. read/write speeds were doubled on benchmarks but real world performance felt exactly the same. a high end samsung i installed in a different machine on the other hand, whoa mama! like a whole different animal.

i would definitely do a secure wipe of that drive and start fresh. only then can you tell where you are at.

How full is the V3?

did it act like this immediately after the clone?.. or only after you started running it full of random/incompressible data with those benchmarks?

PS. looks like the clone caused a misalignment there.
