IOMeter - Average Transaction Time (rev 1)

Back with the Kingston SSDNow V Series 40GB review, I revised the layout of these graphs to better show SSD latency and access time.  First, I have removed HDD results as they throw the scale too far to tell any meaningful difference in the SSD's you are trying to focus on.  Second, I have reduced the queue depth scale down to 4.  In practical terms of a running OS, queue depth is how many commands are 'stacked up' on the SSD at that time.  An SSD is so fast at servicing requests that typical use will rarely see it increasing past 4.  In the cases where it does, there is so much going on that you are more concerned with IOPS and throughput at that point than transaction time.  The below charts are meant to show how nimble a given SSD is.  Think of it as how well a car handles as opposed to how fast it can go.

Some notes for interpreting results:

  • Times measured at QD=1 can serve as a more 'real' value of seek time.
  • A 'flatter' line means that drive will scale better and ramp up its IOPS when hit with multiple requests simultaneously.

I know this is off topic, but whatever happened to intel's DC P3500? Is that ever going to be released?

The DC P3500 is suppose to be released by the end of August. I am waiting to buy one when it does.

.50/GB is decent, but I would love to see everyday prices dip into the .30/GB range or below.

Think it won't happen until we start making over 1.5tb in 2.5"

Based on how the SSD prices have been declining in the last 2 years, I think that $0.30/Gb is obtainable within 2 years easily, regardless of whether or not 2.5" 1.5Tb hard drives are available. I have had a 2.5" 1Tb Hard drive since 2009 and there hasn't been any indication that there is any demand for anything larger for a laptop. I have seen 2.5" 2Tb hard drives but the height is too tall to fit in most laptops.
