Raid 0 is slower when I more non raid drives.

[Adam Sikorski]

Alright so recently I had to format all my drives (2 SSD's in Raid 0, 4tb HDD, and a 4tb SSHD).

After taking out all my drives and freshly installing Windows 7 on my Raid 0 SSD I noticed a HUGE increase in speed. EX: The windows logo animations didn't even get a chance to finish and I was already on the desktop. (It was never this fast for me before)

I was so happy but when I inserted my other 2 4tb freshly formatted drives I noticed a HUGE delay on startup and performance. I had to wait for the windows animation to finish before I was in the desktop.


I'm wondering if it is normal for Raid 0 performance to be slowed down if more drives are added.


IMPORTANT: To clear things up I only have two SSD's in a Raid configuration. The two hard drives are NOT in any raid array.

Your results are strange.
Is your raid chipset intel or amd?
AMD does not perform as well.

FWIW:
At one time, I had a Intel X25-M SSD. It worked well, but I needed more space, so I bought a second.
I really wanted a 160gb single image for the "C" drive, so I combined the two in raid-0.
It worked well, but I could not detect any improvement in my user experience.
Later, I used the 80gb drives in other PC's and replaced them with a single X25-M 160gb drive, and performance was equal, if not better.
