Hi,

Please shed some light of you can, I'm trying to get my full disk IO but haven't had much luck with my research. According to the specs page my machine (Lenovo Thinkcentre m72) is capable of SATA 3 but I'm only getting SATA2 speeds. Any help would be appreciated.

Code:

root@mispc4-deb:/boot/grub# dmesg | grep SATA
[    0.627200] ahci 0000:00:1f.2: AHCI 0001.0300 32 slots 4 ports 3 Gbps 0x3 impl SATA mode
[    0.635796] ata1: SATA max UDMA/133 abar m2048@0xf7206000 port 0xf7206100 irq 43
[    0.635798] ata2: SATA max UDMA/133 abar m2048@0xf7206000 port 0xf7206180 irq 43

[    0.954849] ata2: SATA link up 1.5 Gbps (SStatus 113 SControl 300)

Code:

root@mispc4-deb:/boot/grub# hdparm -I /dev/sda | egrep "Model|speed|Transport"

Code:

00:1f.0 ISA bridge: Intel Corporation H61 Express Chipset Family LPC Controller (rev 04)
...
ahci 0000:00:1f.2: AHCI 0001.0300 32 slots 4 ports 3 Gbps 0x3 impl SATA mode

The H61 Express chipset doesn't support SATA 6Gbps from what I can tell. It supports 4 SATA 3Gbps ports, which matches what AHCI reports.

You're probably looking at the wrong page (please link to it). From what I can tell, Lenovo has a multitude of products named "Thinkcenter m72" ranging from All-in-one machines to full-sized towers.

Thanks Seasons.

I can't find the specs page I was looking at now, but it's irrelevant seeing the chipset specs.

I'll call that solved.
