SATA 3.0 problems

[mir]

Hi all,

Newly installed nas4free (9.1.0.1 - Sandstorm (revision 531)) with SATA 3.0 disk and controller will only run as SATA 2.0. I have tried this tuneable in loader.conf:
hint.ahcich.X.sata_rev="3". But that did not help.

Any ideas?

Specs.

Revise your BIOS config.

SATA Disk can be in AHCI mode, not in IDE or compatible mode to use Full SATA 3 Speed.

revise your SATA cable too, , use a short and good cable, with metalic clip retention: http://www.alternate.es/html/product/De ... =7&lk=3859

BIOS setting is in AHCI mode. I have also disabled combine SATA and IDE mode. Cable is short (30 cm) and with click locks.

Peculiar:-)
Controller supports 6 SATA ports but MB only have 4. Moving the connectors to the other two ports and voila:
ahci0: <ATI IXP700 AHCI SATA controller> port
0xf140-0xf147,0xf130-0xf133,0xf120-0xf127,0xf110-0xf113,0xf100-0xf10f

ada1: <ST31000524AS JC4B> ATA-8 SATA 3.x device
ada1: 600.000MB/s transfers (SATA 3.x, UDMA6, PIO 8192bytes)

Any logical reason to this behavior?

[raulfg3]

No, but at the end you don't notice any improvements in speed ( the real bottleneck is the Transfer of the disk).
Please do test if possible to see if my aseveration is correct or not

Edit: Ok , you notice some improvements, is good to know.

Well, is does make a difference - significantly lower CPU and RAM usage. Performance increased by 3-5%. I have a lot of tests done with iozone, fio, and bonnie++ I can provide but I will have to remake tests after the change

I have the same problem. I have ahci set for all sata ports in the bios.
I did not add anything to loader.conf
do I need to change a diffrent setting?

You can try to add the following to loader.conf

You have tried connecting to other SATA ports in your MB?

Same problem here:

SATA controller and disks are correctly recognized as SATA 6 but they are connected as SATA 2. BIOS setting is in AHCI mode.
I added ihint.ahcich.X.sata_rev="3" to loader.conf but no luck.

Does anyone knows what else I can do or try?
