Edge Computing Division Users Forum

Hi all,

I do have a fitpc2i revision 1.1 and installed Ubuntu 10.4 on it.
Initially the "classic way", which could not boot from SATA, but from USB and later on I followed the instructions in this forum so it also works from SATA now.

What's strange is, that the time it takes to compile a kernel (ca. 15 min.), which can be used to measure hard disc performance, is about the same both from SATA and form USB.

I would expect SATA to be significantly faster than USB.

Did someone else observe this strange behaviour?

Regards,

Robert

Is this so?

Indeed, however, keep in mind that we have a SATA-PATA bridge in the fitPC2. But even PATA should be faster -- however 60MB/s is not that slow as it might seem in these times. I myself run the system completely from USB2.

I don't think that kernel compilation time has any correlation with disk speed.

Anyway, USB2 will provide effective speed of 30MB/sec. SATA connector inside FitPC2 gives 60MB/sec for 5400RPM HDD, and around 90MB/sec for fast SSD.
