It's not just a thing you can buy my friend.
It's multiple things you have to buy and set up.
You have to have at least two SATA hard drives, a RAID controller, and a motherboard that supports SATA connections.
My ASUS motherboard comes with the connections and built in RAID controller. Most people have told me that RAID is for servers and such.
Sure. But does it work for all other things? You bet! Wow...I have the need, the need for speed!
Here is the weird thing. Western Digital, Seagate, and such make these drives that can move information so fast that the CPU companies are playing catch up.
In a sense, the hard drives are waiting for the CPU's.
But will the CPU companies make a chip to match or exceed the drive speeds? No! They will soak you for more upgrades along the way.
Such is the computer way...
