2x WD Velociraptor@raid0 slow or just right?

post #1 of 20
Thread Starter 
I'm a complete noob about hdd's. took me hours to just finish configuring my two velociraptors at raid0. when I did the WEI on windows 7 and I only had a score of 6.1. is this normal?

HDtune 2.55 benchmark

WEI is the worst indicator of performance besides personal bias bar none - they look normal, good solid performance across the board

so they're normal? I was a little worried about the HDtune benchmark. performance decreases over time and the graph is static compared to others that I've seen that are straight and linear.

With regular hard disks you will always see this gradual drop off. The first portions of the volume are moving under the read head faster (because of the greater circumference).

You will only see a straight graph in the event of a greatly short stroked volume, or with an SSD.

so those are ssd's that I've seen. thanks +reps given.

how does my hd's compare to a single SSD. is a SSD still much faster than two velociraptors at raid0?

Here are my two WD RE4's 500GB in RAID0. My tranfer rate is much better, but it's your access time that kicks ass. That must be why you got a WEI of 6.1. I thought youu couldn't do better than 5.9 with mach. drives.

ah I see. what does those numbers mean anyway? what's access time? is it that one that makes the pc boot faster?

wow the difference was so much. ssd's are blazing fast

I wonder what's the difference between my two Vraptors @raid0 and my previous WD 500gb caviar green. is it a huge jump in performance?
