Also going back to the old hard drive speed thing, should i need RAID0 for a fast system? atm its a 5400rpm eco drive as the secondary HDD. Would i get enough speed out of just one 7200rpm drive or do you think RAID0 is worth it?
You can mix drives in a RAID0 but you will not get optimum performance. For instance if you have 1 500GB drive and another 750GB drive then your RAID0 would only have a 1TB capacity due to the minimum drive size being multipled my the number of drives. In this case it would be 2x500GB for 1TB of RAID0 space.
As for mixing speeds of drives, I believe this can be done (not 100% certain) but you would have the same effect. The RAID speed would be limited by the slower drive. So where two 7200RPM drives with access times of 4.2ms in RAID0 would have an access time of around 5ms due to having to seek through two drives instead of one drive. A RAID0 with a 5400RPM drive with a 6ms seek and a 7200RPM with a 4.2ms seek would have a seek time closer to maybe 6.5-7ms due to the seek time on the slower drive.
RAID of any type 0,1,5, or 6 use identical drives so that you maximize performances and capacities.
As for using 1 7200RPM drive, it is what the vast majority of the world uses and probably a slim majority of OCN as well on a day to day basis. I'm not going to try to make up your mind for you but I will lay out the facts about it all. And in a nutshell it comes down to whether you want to risk data for the sake of speed or have the redundancy of a backup drive. That is the big factor that needs considered most when it comes to determining if you want a RAID0 setup or not.
EDIT (at work, slow response time from me sometimes):

When pulling from my SSD writing to my 2TB, it was transferring over 10 times faster (at around 220.127.116.11 GB/s)
You would see a HUGE improvement replacing that 5400RPM drive with one that is 7200. I would try it first, and if it isnt fast enough, look at ordering another one and setting the raid up. Just make sure you pick drives that will run good in RAID. There is a whole section of people using consumer drives to run their house hold raids. Make sure if you are running a RAID0 to take like weekly backups and put them on another drive like an external one though.
Thanks for providing some reference points with numbers. And I agree, replacing the 5400RPM will make a difference I just like to resolve things without spending money because I'm cheap like that
But yes it would make a huge difference, and if you do end up getting a second drive, if you can, try to get one identical to the current 7200RPM so as to have as ideal a setup for RAID if you go that route.Edited by NameUnknown - 6/5/13 at 7:07am
