Post your hard drive benchmarks!

The 15K Cheetahs are actually very quiet. I used to run 3 of them striped on a PCI-X Raid controller back in the day and they were great. However, for normal PC user type-stuff, there were no noticeable performance benefits over SATA raid arrays that I have run since. I just liked knowing that I had them :D ;)
 
That's the point... a SATAII drive will boot into windows quicker from a switch on, whereas with the SAS drive, the HBA has to initialize, scan the bus etc..

It is noticably faster than my Baraccuda 7200.10 though, but not 600 quids worth noticable!

I didn't pay for the drive or the SAS controller, they were the result of a screwed up order on a server, and they never asked for the old ones back! All I had to buy was the SAS fanout cable.

wow.. u had a good deal then..

your results for your 300gb 15k.5 are damn good. my 146gb 15k.4 manages abt 77MB/s average..

I found it's better to use Flash Memory Toolkit to measure performace. I found HD Tune gave me false readings for my flash card.
 
Here are my disks first my c:windows disk a nvidia raid on k8we

Do you have NCQ turned on for those drives? The trace is kind of peaky which suggests it may be on, NCQ seems to try and second guess the RAID requests which screws up the transfer rate.

It's worth checking with NCQ off.

Sooner I get a new sata HDD the better, results with that thing are all over the place. Probably should format it as well.

I have just configured both the 7200.9's into a RAID 0.

You guys think I have achieved much of a gain: -



Oh and how do you make the pictures big so you dont have to click on the small pic to be taken to imageshack browser page.

Here is my quad hitachi 80gb raid 0 array, nf4 controller, ncq off, read cache turned off.
Quite fast for £60 :D





Need to invest in a decent raid controller with some cache, nf4 seems to really limit these little devils.
 
One of the fastest if not the fastest drive available!! (I have had a Seagate 15k4 but me Atlas II's are faster imho)

I wasn't aware that these drives had NCQ on them to be fair.
