Pillar mentions in SSD market history

March 2009 - Pillar Data Systems launched the Axiom SSD Brick, a storage module with upto 12 Intel SSDs which is compatible with Pillar's distributed RAID systems. Pillar's application aware QoS software dynamically chooses storage types (SSD, FC-HDD, or SATA-HDD) and tunes performance to satisfy quality of service priorities based on user selections for each type of application.

In September 2009 - Pillar dumped Intel SSDs due to flaky operation and switched to STEC. Maybe they should have spent a bit more time qualifying the Intel product beforehand - or done a better job at it?

In December 2010 - December 4, 2010 - Mike Workman, CEO of Pillar Data Systems recently published a blog - Cache Works – Sometimes. In it he demonstrates why one of the failures of reality versus expectation in enterprise SSD acceleration is the "average flash cache performance" beloved by marketers. It's the peaks which are the memorable parts of the apps speedup experience. The blog site has now disappeared - but many of the blogs are now available as a free pdf download (click for summary and link).

This article will help you understand why some SSDs which (work perfectly well in one type of application) might fail in others... even when the changes in the operational environment appear to be negligible.
