I know this question has been asked a million times here and the answer always is RAID 10. I understand that RAID 10 offers better performance but my question is at what point do you realize that performance?
I have a server with 16GB of RAM, 4 x 500GB 7200rpm sata drives and a 6 core processor. The SQL database is 4GB and I will have 15 computers accessing the db but not all at the same time. With this amount of data and access really see a benefit from RAID 10?
RAID 5 allows me to keep more disk space for the growth of the data. There is also a working folder of data that is about 250GB that grows along with the db. I don't want to "waste" the extra space to make a RAID 10 array if it won't really benefit me.
I would like to hear answers based on this specific information and not just general info on how RAID 10 is better!
Thanks
