Read this, especially the OLTP and Email section: http://www.tweaktown.com/reviews/6337/edge-boost-pro-300gb-enterprise-ssd-review/index.html It trails far behind other SSDs (and surely the 3700 which is about the same price). Though typically the journal is actually NEVER read from, so write performance is the main point here. This SSD looks good in the random write section. However the Sandforce controller is known to slow down things during garbage collection. There is also the question how much this drive will degrade with time, at least the review above did some preconditioning unlike others I saw. With journals, you can't really to a TRIM to clean up things. OTOH with a 240GB drive you can leave most of it empty for prevent or at least forestall these issues. Finally there is NO specification on the makers homepage at all. So when it comes to durability and the buzzwords plus Toshiba eMLC mentioned in the reviews do not solid numbers make.
