0.2ms access time?

post #1 of 5
Thread Starter 
So I was bored and decided to run WEI just for kicks. My SSD usually gets me 7.7, but for some reason this time it got me 7.6. So I decided to run HD Tune on my Corsair Force 60GB. It didn't go too fast, it never did really. For some reason it always ran slower than my Nova even though it's supposed to be faster and better. Anyways, when I ran HD tune the Transfer rates were a bit slower, ran it again, then it went even slower, ran it again then it went faster than the first time. So I'm just like whatever really. But what boggled my mind was that all three times I ran it, I got 0.2ms Access Time, when I used to get 0.1ms.

I hear that when SSDs fill up, they tend to slow down a bit. Can this be the case? Or is my SSD just starting to die on me. I only have 16.9Gb free on it... Yeah, I think I started last week with 21Gb then my space is somehow vanishing. If you can solve that it'd be much appreciated as well, haha.

So in conclusion... Why am I now getting 0.2ms Access Time on my SSD?

Thanks!

If you have it installed on the intel controller you could try to reinstall the chipset drivers. I noticed that my ssd was erratic after a windows install and it was all because the chipset driver was screwed up and a driver reinstall fixed it right up.

hdtune only gives you rounded off numbers for latency. Use AIDA for latency measurement that is accurate

I downloaded the Trial of AIDA64. My Corsair Force averages .16ms while my Corsair Nova gets .09ms. I guess that's not too bad to live with right? Haha.

For some reason my reads were a lot higher than when I did it in HDTune as well. Weird.

I would recommend using AIDA mainly for latency measurements, however, you can change the settings so that it will test different file sizes with its read numbers. The reason you are seeing different read numbers is that it is using the "optimal" file size to test with, whilst HDTune tests with a different file size.
the best for SSD is gonna be AS SSD. but dont use it for latency LOL. the reason is that it use 512b as the measurement, which is a god knows why type of thing. the latency is measured with 4k@QD1.
A good friend developed this benchmark. It is by far THE BEST test of SSD performance yet. Look at the 4kQD1 measurement and this will tell you the latency.
