I like to use hd tune to benchmark my drives and have read about 4k IOPS being a good measure of real world performance.
is that just for ssd and not valid for regular hard drives?
I just set up raid 0 with three 500gb drives and its seems pretty fast but it only gets 115 4k iops.
compared to a vertex plus ( the cheapest 60gb drive ) gets about 6700 4k iops
and my sata 3 corsair force 3 is getting 4600 4k iops ( interesting that its less then the vertex plus)
any way there is no possible way that the raid setup i just made is 60 times slower then my vertex
it seems quite snappy in my limited time on it I am pretty happy with it.
so what should i be looking at????
I am open to a different benchmarking tool but also just a different number on hd tune
the 4k ios refers to access times of the drive and yes those numbers are most likely correct. think physical drive with something like 8.9ms or 12ms while a ssd has something like .1 ms
