AT Article on IOPS?

Hey guys,

I'm trying to hunt down an article I was reading on the AT main page a few weeks (or maybe a month or two?) talking about the relationship between iops, latency, queue depth, and transfer rate. I thought it was its own article, but maybe it was on the first page of a product review?

I did some searching on google and AT, but I couldn't find it...anyone have any ideas?
 
I don't recall ever seeing one. For simplicity:

Transfer rate = Read/write speed, usually maximum
queue depth = How many disk requests (work) are in line to be serviced (done)
iops = -something- operations per second = How many disk requests done per second
latency = how long it takes for the HDD/SSD to perform a disk request

Yes... yes... others will chime in a correct things but in general, it gets you in the ballpark. As for the relationships... the combinations are exponential. It's probably best if you stick with trying to solve a problem (slowness) that you have, if any.
 
Oh, I know the relationship. It was just explained in a very good way, and a buddy of mine is getting into IT, so I just figured if someone had a link offhand, it'd be useful. I swear this was just a few weeks ago...maybe it's just me spazzing out.
