If you want performance stick with RAID 10. In general the more drives (spindles) the faster the array. The Western Digital RE3 500 GB drives are a good deal. You should be able to get 4 of those in the low $200s. In RAID 10 this would give you better performance than 2 x 1TB in RAID 1.

So, if you have 4 x 1TB drives, think of it as two separate 1 TB volumes. The system will write half your data to volume A and the other half to volume B. The data in volume A and B do not overlap.
Now, each volume is composed of a mirrored set of drives. Anything written to volume A is actually stored on two drives. Anything written to volume B is actually stores on the other two drives.
Does this make sense? Let me know if you need any more explanation.
No it makes sense.
I am contemplating if I really need 4 x 1tb in this system. I mean how much space with some photo's, web pages and MySQL take up if there are 5,000 subscribers to start up?
Would 2 x 1TB enterprise drives be enough mirrored?
Also, when you move to a hosted solution, I would appreciate your considering my company for it.
Sure, I will be doing a lot of research on that for sure. _______________________________________________ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
