Which ssd benchmarking utility?

[bononos]

Which benchmarking utility is recommended for ssds to guard against bait and switch products (eg Kingston v300)?
IIRC ATTO uses compressible data which makes ssds look good but may not necessarily reflect real world tests.

AS-SSD, I guess, to answer your question.

But I think you've got a flawed premise. If you don't have a Sandforce controller, it doesn't matter - the SSD isn't using compression to speed things up. Okay, so the Kingston V300 is using it, but Sandforce is not really considered "enthusiast" class anymore.

If you do have a Sandforce controller, then using compressible data or incompressible data isn't really what matters. Sure, it'll effect the benchmark speed, but the "accurate" benchmark is the one that best reflects the real-world use case. So whether one or the other (or a mix) is better depends on your workload. In the case of sandforce, compressible data is the best-case scenario, and incompressible is the worst-case. Reality exists somewhere in between, as always.

To protect against a bait-and-switch, you would want to make sure your test setup mimics the one in the review you're using as a reference point. So if they use SSD benchmarking tool ____, then you use SSD benchmarking tool _____. If they run Linux and use DD, you run Linux and use DD. Etc. Otherwise, it becomes very difficult to say with certainty what's going on.

As for the V300, I actually have one of the "bad" ones in my hackintosh.

*shrug*

Still faster than a HDD. It was also cheap as hell because of all the bad press Kingston was getting. But it's still got SSD-fast random access, and because its sequential read/write speeds - even crippled by bad NAND, and even with incompressible data - are faster than anything I can connect to the computer short of another SSD, I'll never be able to tell the difference.

I won't be lining up to buy another Kingston product - I mean, I did buy it expecting performance closer to my old Vertex 3 or the other Sandforce SSD I have in my old laptop. And this doesn't even come close. But in my old age I find rage is harder to sustain and less fulfilling when I do manage it.
