Interestingly, end-users with firmware version 3.0.5 will not get the same performance as seen in reviews, because the 3.0.1 release candidate firmware used on the review samples did not have this performance cap in place. SandForce reportedly introduced the performance cap to fix a known reliability issue that could result in a dead disk.

Not all SandForce SF-1200 based SSDs will be equal though, OCZ has a closer relationship with SandForce than other firms, they've committed a lot of resource to the company, and therefore they will get access to a faster revision of the SF-1200 firmware.

Corsair is currently shipping SSDs with the 3.0.1 firmware, but the company claims it has circumvented the reliability issue by disabling the power saving feature that caused it. AnandTech has investigated this claim and testing seems to back this up as the power consumption of Corsair's Force 100GB is 1.25W during a sequential write test, while the OCZ Vertex LE 100GB uses only 0.95W.

Corsair could keep shipping the faster 3.0.1 firmware, but if users ever have to upgrade they will lose performance.
Now we get to the other problem. The performance of 3.0.1 is the same as OCZ
