SSD vs enterprise SAS and SATA HDDs

AnandTech has published another interesting article about solid state disks, this time they investigate how SSDs compare to enterprise SAS and SATA disks. You can read it over here.
Let's face it: buying, installing, and powering lots of fast spinning disks just to meet the Monday morning spike on mail servers and transactional applications is frequently a waste of disk space, power, and thus money. In addition, it's not just hard disk space and power that make this a rather expensive and inefficient way to solve the ancient disk seek time problem: you need a UPS (Uninterruptible Power Source) to protect all those disks from power failures, plus expensive software and man-hours to manage all those disks. The Intel X25-E, an SLC SSD drive, holds the potential to run OLTP applications at decent speeds much simpler. Through a deep analysis of its low level and real world performance, we try to find out when this new generation of SSDs will make sense. Prepare for an interesting if complex story...
