Which drive in my PC has better performance?

[TechStuey05]

Hey guys,

I have an Asus P8Z68 Deluxe Motherboard and 2 Hitachi Hard Drives. My Boot Drive is a WD Caviar Black.

My PC is running Windows 7 64 bit. I ran the "Benchmark" for "HDTune" for 2 of my Hitachi Drives and here are the results:

Why is the burst rate so much faster on the first Drive? Which Drive has better Performance?

Perhaps one of them is connected by Sata 3 and the other is Sata 6?

Any info is greatly appreciated

Those drives have essentially the same performance even in the benchmarks, and likely have zero real world difference. The burst mode is how fast data moves from the drive interface itself to the controller, could be dependent on the SATA mode, cache etc.
