Regarding SATA:

This chip is not actually AHCI compliant - I recommend you read the introduction of the spec if you don't understand objectives and roles from this spec. It doesn't imply anything relative to performance or reliability. It means that support by future OS (Linux, Vista and OSX) and interoperability with other Serial ATA components (drives, other chips) COULD be of lesser quality - this depends more on Silicon Image support evolution in time and the maturation of their product interoperability tests.

Interoperability, features and extensions supports testing are currently done by industry participant internally and in plugfest from which no results are published.

Serial ATA standards, extensions are really fragmented and this situation is a total mess for the consumer.

The current state of interoperability between SATA devices is good in numbers of peripherals that COULD work but quite poor in features supported between them (see firmware updates of numerous drives notably the latest Maxtor/nFORCE history) .

For example there are no standard or label validation tests that say Sil3132 supports 3Gbits/s rate (Serial ATA 2.5 tries partly to correct that). It doesn't mean that Silicon Image doesn't do its maximum to make it work reliably at this rate and that Sil3132 doesn’t work at his rate with some drives
Nonetheless it clearly doesn't work (or so say the driver inf file) with NCQ with some drive that say to support it too because of incompatibilities.

For a few bucks, all these things don’t really matter for my personnal use. At work the situation is different: I buy only AHCI compliant controller and carefully qualify the references of my hard-disk drive.

（这篇揭示了一点有用信息）
随后Intel推出的i915/i925的ICH6/R开始提供AHCI界面（只有ICH6-M和ICH6R支持AHCI，普通版ICH6也不支持），以支持NCQ（Native Command Queuing，本地指令队列）功能，ICH6-M/ICH6R通过AHCI界面提供了有限的SATA 3Gb/s特性，接口速率仍为150MB/s。

今年Intel推出了i945/i955芯片组，里面的ICH7/R才真正支持300MB/s的界面速度，并提供了大量的SATA 3Gb/s特性。和ICH6/R的情形相似相似，只有ICH7R才支持AHCI界面，普通版的ICH7也不支持。很明显，带R与不带R是Intel南桥划分市场层次的一种手段。

而JMB360 3.0Gbps兼容测试通过：

这款JMB360已于今年4月获得了PCI-SIG认证，其PCI Express兼容性已达到最佳化。而且JMB360也通过了客户端对3.0Gbps串行ATA II硬盘兼容性测试，同时JMB360还支持Port Multiplier、eSATA等功能，

而智微科技此次推出的产品为型号JMB360的PCI Express至Serial ATA II控制芯片。此项产品可应用于主机板(Mother Board)上，通过2.5Gbps PCI Express总线连接最新型的3.0Gbps串行ATA II硬盘，达到最佳开机与存取的速度。

结论：可能3112和ICH6R一样（ICH6R通过AHCI界面提供了有限的SATA 3Gb/s特性，接口速率仍为150MB/s）！
