![]() This is not a high frequency if you compare it with competitor products. 3ware still does not specify the processor clock rate but, judging by the marking, it must be 266MHz. The marking differs in the serial number: AMCC Power PC405CR. Interestingly, the controller’s main processor is the same as in the 3ware 9650SE we discussed in an earlier review. They are all based on the same processor, equipped with 512 megabytes of DDR2 SDRAM clocked at 533MHz (desktop PCs used to have that much system memory just a few years ago!), and have PCI-Express x8 interface. ![]() Otherwise, the controllers in the series are all identical. And finally, the -4I model is equipped with only one internal port. ![]() The -8E model has two external SFF-8088 connectors, and the -4I4E has one internal and one external connector. The 8I model we have got features two internal SFF-8087 connectors each of which provides up to four SAS ports. The 9690SA series offers four models differing in what connectors they have. Other 3ware controllers support SATA and the 7506 series even supports PATA. The 3ware 9690SA is the only series of RAID controllers from LSI 3ware family that supports hard disk drives with SAS interface.
