stripped, the 2 250gb drives are seen as 1 500gb. there is about 200gb of free space
In that case, you have about 300GB of data. Do you know what the usage patterns are? In other words, what is running on this server? File shares? database? Web server? Also, is it mostly reads from the drive, mostly writes, or can you estimate the percentage of each? What are your expectations as far as where you expect your data usage to go in the future? Is it going to stay ~300GB, or is it going to steadily creep up over time?
