Some Questions About Raid

post #1 of 7
Thread Starter 
Hey People!
I'm about 1 or 2 months away from building my first computer and I could use some information about Raid.I'm thinking about Raiding two Samsung Spinpoint F3 1TB HDD's in Raid 0, Although further down the road I would like to Raid two OCZ Vertex 3 240GB in Raid 0, Though I would like to have them Raided seperatly, As ive heard if you Raid a HDD And a SSD together that the SSD's performance would be dropped,Is it true that the SSD's performance will drop when raided with a HDD?Also if so is it possible to have the SSD's and the HDD's in Raid 0 seperatly?
Thanks for the help!

Whoa there......

For a raid array you generally need identical drives, they can be a little different, but not much. SSD and an HDD...no way.

In a raid 0 setup, the data stream is split, so that 1/2 the data goes to (or comes from) one drive and the other 1/2 to (or from) the other. There is no provision for caching (ie temporarily storing) the data going to a faster drive while waiting for the slower drive to catch up. The raid software just slows down the whole data transfer to match the speed of the slower drive.

Also, be aware that you have to (well, it's ALOT easier to) set up a raid 0 array during an operating system install, to a blank, formatted, set of drives.

There are many, many articles about the various array types, their advantages, and limitations.

I said that I wanted to have two OCZ Vertex 3's in Raid 0 Then I also wanted two Samsung Spinpoint F3's in their own Raid 0, And the HDD's And SSD's I wanted in Seperate Raid 0's, It's kind of hard to explain, But like the two Samsung F3's On Their own Raid 0 then the OCZ Vertex 3's in a seperate Raid 0, Is it possible?

If your RAID controller that supports RAID 0 has sufficient ports then yes it is possible.

Suggestion: Don't put the HDDs in RAID0. I am assuming it will be storage and with RAID0 you will have a 2x failure chance. You don't want that to happen -- trust me RAID1 is better. For programs and OS RAID0 is great on the SSDs, but unless you are going to be editing HUGE files and need to save to them quickly, do not use RAID0 for the HDDs.

A controller can easily accommodate multiple seperate arrays assuming you have sufficient SATA ports on the controller itself.

Also, as stated, RAID 0 significantly increases your chance of data failure. If any of the drives in the array were to fail, you will lose all data contained on that array.

Addressing your question of mixed RAID with SSD and HDD, generally not the best of ideas. While it may work, the SSD will always be waiting on the HDD to load, effectively gimping the array speed equivalent to the speed of 2 HDD's. The base performance of any array will be affected by the slowest disk in the array.
