Limited by Sata 1?

[Andrew1990]

Well I have my Raid 0 set up and I am getting great speed. The one thing I forgot though was to check to make sure the drive's jumpers were set into the SataII mode.

The drives are getting close to the 150mb/s mark and was wondering if they could go faster if they are set to Sata I now. I would open up the case and double check but the case is a mess and hard to connect the HDDs back up.

Here is a HDTune chart

As you can see it is somewhat on the border so this is why I am concerned.

look at the min and average figures, i bet its only two drives, right? the SATA is probably not the limit.
1. The SATA is limited to 1.5gbps (divide by 8 for BYTES instead of BITS) you get 187.5MB/s, some is overhead, but its still a PER DRIVE figure, unless you have raid0 on an external enclosure and the entire enclosure is connected to the PC by a SATA1 port than it is not an issue.
2. the min and average indicate that you wouldn't go any further anyways...

With SATA you have to divide by 10, which gives 150MB/s for SATA 1

Ok, thanks. Ya it is only 2 drives.

I guess I'll not even waste my time checking the jumpers then as of this moment.
