Strange? Does dmesg reflect any difference in AHCI version or PHY speed, on either machine? Did you use the same cables in both tests? AHCI version ("0001.0100" == AHCI 1.1): ... ahci 0000:00:1f.2: AHCI 0001.0100 32 slots 4 ports 3 Gbps 0xf impl SATA mode ... PHY configuration and speed: ... ata1: SATA link up 1.5 Gbps (SStatus 113 SControl 300) ... SATA headers (ports) on the motherboard and SATA cables are known to be weak links in the chain, commonly.
