"Raid 0 SAS" versus "2nd generation SSD"

"Raid 0 SAS" versus "2nd generation SSD"

"i was planning to buy a SAS system made of two 15k RPM disks in Raid 0 configuration to give a boost to my s.o. and my apps... but after i saw that article on Coding Horror, i've started to thinking if a new 2nd generation SSD could do the same job, or even better...
Does anybody have any information to help me decide?"

"With RAID 0 you have that chance of failure and losing everything, and you still get read lag. With an SSD, you have a lesser chance of losing everything, and no read lag at all. That means when you open something it will begin to load almost instantly, unlike traditional HDDs where the read head has to be physically moved into position.

However, with your SSD you'll also need another HDD (If you're considering raid 0 you're probably not the sort of guy who can get along with 128GB of storage space ;)), but that carries it's own advantages. I think the Small/Fast SSD and Big/Slow HDD method is about the best you can get for reasonable prices right now.

edit: John makes a good point, SSDs are silent and require much less power, as well as giving off less heat."
