ahci: SSS flag set, parallel bus scan disabled Plugged it in and the BIOS shows the card is in AHCI mode, as I already had AHCI SATA enabled in the kernel it was picked up just fine: I went ahead and got myself one of these: Ģ port MiniPCIe based SATA controller that uses an Asmedia 1061 chip. Because I'm running a SATA300 port multiplier I don't expect to make those speeds but at least well over 130MB/s would be nice, 250MB/s would be more in line with my expectation. It appears that despite being SATA300 the card/chip has an internal limit that is bottlenecking my disk IO.Īfter doing some research I found that the Asmedia 1061 chip is very cheap and it is capable of reaching speeds well over 300MB/s. This works fine but I am not able to get more throughput than approx 130MB/s through the Sil3132. There are 5 3TB WD30EZRX disks attached to the PM stuffed in an mdadm raid5 array. Currently it has a Silicon Image 3132 based 2-port SATA controller installed, the second SATA port is attached to an Addonics SATA port multiplier. According to specs it has a PCIe 1x v2 bus capable of 500MB/s. I'm running an Intel D510MO mainboard with has a MiniPCIe slot.
