I just new server to run SAP business one on. With the speed of SSDs it minimizes the need for raid. We only use raid for redundancy and not for speed boost like traditional SAS drives. I love the simplicity in architecture. Even though it is not a PCI express SSD the random read and random writes is quite fast. The time it takes from running an aging report went from 2 minutes to 5 seconds. With the speed of the SSD in case the index is not rebuilt on the SQL server it does not degrade performance as much. I am running traditional SAP and a lot has changed in hardware in the past few years.

    Man, you only said the good thing about SSD, but you didnt mention the bad thing. The only bad thing actually is the writing endurance of SSD. All SSD will fail faster than traditional HD due to that.

    So for those who wants to adopt SSD in your installation, I would suggest to study that. Anything else from SSD is great.

      We did study and we got enterprise SSD and not the normal desktop ones. The NAND on this is the same as PCI express version that Intel uses. I heard that fusion-io is among the best due to the controller, but reads with production data around 800 Mb, which is about 100 MB/s is quite good. Also the box runs cooler overall. Now we can experience close to 100% CPU loads when running during the day. The bottleneck is less the disk but the software.
