Itel rapid storerage. IRST advantages on single disk configuration

​Hi,​

​I always set sata mode to AHCI.​

​Now I read on the Intel site that a single disk configuration also can take advantage of performance and lower power consumption. I have read before somewhere on a forum that someone indeed experienced longer battery life.​

​What is your opinion about IRST?​

​Intel® Rapid Storage Technology offers greater levels of performance, responsiveness, and expandability than ever before. ​​Whether you are using one or multiple serial ATA (SATA) or PCIe drives,​​ you can take advantage of enhanced performance and lower power consumption from the latest storage technologies. Additionally, you can rest easy knowing you have added protection against data loss in the event of a hard drive failure. ​​View larger image ›​
