Do i Need all my HDD's to be the exact same make and model for RAID 5?????

Basically, the title says it all.

I am preparing a server for Hardware Raid 5.

My question is do i need all the HDD's to be the same exact make and model and size, or can i choose what ever i want?

They do not have to be the same make and model. They can be compatible drives. I have done that before with RAID 5.

The new drive can be bigger, but it will only extend to the original array size. No point in bigger if you can get the original size.

You can choose whatever you want, however, the OS may limit the amount of total HD space if they're not the same size, or performance if they have different attributes (ie, cache).

We’d all like to think our company’s data is well protected, but when you ask IT professionals they admit the data probably is not as safe as it could be.

its a dell server by the way
it came with a add-on PCIE Raid Controller and i was in fear that it would only work with the HDD the Server came with!

Dell sells their HDD's with ther T110 poweredge server's WAY TOO EXPENSIVE!!

I Dont Understand why they are so damn Expensive.

So this is the reason i asked cause i am not going to spent $600.00 on getting 2 more of those redicoulously expensive drives
If they'll fit standard-sized 3.5' internal drives then you're OK, but from what I've heard, they slightly tweak them so only the Dell brand will fit.  I would try and see if a regular HD will fit into the casing.  If it does, you're good to go.
