Seagate 500GB 7200rpm in - T61 limits speeds to 80MB/s :( .. lame

well .. it's my T61 that limits to 80MB/s The HDD by itself works fine as if I continue the line from the middle to the left as it's supposed to be, it will most likely hit those 100MB/s at the beginning. However, that's not happening on my computer. How lame that is for Lenovo...

it's much faster than my old HDD though, but still

I've tried in compatibility mode too - same thing.

 

Shouldn't the limit be 150mb/s, so in actuality you should still be able to get over 100-120mb/s.

Its weird, i thought i saw some benches for ssd's in t61's that hit over 100, i'll have to look.

Edit: Found some benchies by Jlingo who got over 100mb/s with intel ssd. So its weird that the mechanical drive would be limited at 80

 

I don't get it. I'm not getting that kind of performance on my 7200RPM desktop hard drive. Isn't that in the normal range for non-SSD drives? As a matter of fact, my 74GB Raptor didn't even fare this well.

 

There are a lot of factors that go into drive speed. Newer drives with high areal densities are actually very fast for sequential activity.

In fact, my WD6400AAKS desktop drive with 2 320GB platters (very good drive, I have 4) is over 100MB/s for reads and writes. This is actually far faster than the 74GB Raptor (for sequential) because the raptor has a very low Areal density (either 1 74GB platter, or 2 37GB platters) and the high spindle speed can't make up for this (the new Velociraptor is much faster than the old one).

The Seagate 7200.4 has 2 250GB platters. As a result it should hit at least 80MB/s (which it is). I think that speed is pretty good, the one thing that worries me is the slow burst speed.

Do you have another computer you can use to test it (e.g. desktop, friends computer, etc.)? SATA laptop drives use the same interface as desktop drives so you shouldn't have any trouble. This will confirm if it is the drive or the interface that is the bottleneck (I think it's the drive).

 

check this out

I upgraded the HDTune version from 2.54 to 2.55 .. and I got same results as before.

However, I changed the benchmark to test at 128KB blocks instead of the default 64KB for the new version, and I got this ^ graph

so it's not my T61 .. yey

 

Weird, I wonder what that means. Glad to hear that its not your t61!
