Kingston SSDNOW V200 Is Having Serious Performance Problems

[x92_fermi]

Maybe because it's CDM not ATTO? The figures given by Kingston are based on ATTO I think.

[Phil]

That's valid for Sandforce drives. The Kingston V200 is based on JMicron.

Yeah I don't suggest turning off pagefile but let's not have that discussion here. It's been discussed at length in the general SSD thread.

Roger that.

I'll go ahead and do a clean install and report back with my findings. If I get the same low readings I'll contact kingston. Could it be possible it is defective? Never had an SSD before so I would not know the symptoms.

[Phil]

It's possible that it's defective but it's more likely it's something else.

PS. when you do the clean install make sure to remove all partitions during setup. I suggest to not do any tweaks.

So basically when i install windows format the drive and install windows?

[Phil]

Delete all partitions, create one partition for the entire drive and quick format it.

[tuηay]

I usually format the drive and let the windows create the partition. But however, I don't think there is a diffrence.

This is the footnote in the spec sheet.

2 Based on “out-of-box performance” with ATTO Disk Benchmark 2.41. Speed may vary due to host hardware, software and usage.

and the number 2 refers to sequential write.

[Phil]

OK. Well my point was JMicron, unlike Sandforce, doesn't use compression. So using CDM instead of ATTO shouldn't make any difference.

Would be nice to try though.

Found some interesting stuff: Someone else that gets very strange performance.

Kingston saying that the V200 128GB should get 257 points in AS-SSD.
