Excellent review, great to see a full gamut of drives and controllers.
Another typo: you write the Plextor M3P as having a capacity of 256MB instead of GB.
Suggestion: I think you should mention that the Octane 4 comes with some DDR3 chips for caching.. what looks like 512MB to me? I presume this helps significantly for it's strong write performance.
All said and done, I think this looks like a solid drive; but I can help but feel the review really highlights how strong the Plextor M3P is for every workload!

Making some corrections now. We were finishing this review at 2am last night out on the road at SNW in Dallas. Thanks for catching those. We are actually making some mid-flight edits right now on our way back to Cincinnati. I'll get the tweaks to the charts rolled out shortly.

I noticed the Vertex 4 uses a 512 MB. cache on the 128 GB. drive and that OCZ is claiming closer performance to the 256 GB drive. Latencies are low but performance in real apps. is average, which seems odd to me.

1) Vertex 4 benched better than most other drives at IOMETER random 4K reads and writes benchmarks, so I expected it to be the best drives at database benchmark. Yet at the IOMETER database IO benchmark, its performance is very lagging, actually worse than Vertex 3. Why is that?
2) Does it come with any capacitors to protect against crash? Or would I lose/corrupt my data if I lose power?

1. Certain drives excel in a given workload, but start to fall back when both read and write activity is measured together. OCZ has stated firmware updates should improve performance in those areas, but how much is still up in the air until we retest it.
2. Most consumer models outside of the Intel SSD 320 offer minimal power protection. The best setup for a consumer workstation is a battery backup such as a UPS.
