StarTech's SATA RAID controller cards come in small, white and yellow boxes. The boxes provide a brief description of the cards and show them from various angles. However, there is very little information regarding their specifications and features.
The contents of both boxes are very similar. Along with the RAID card, you get a low profile bracket, driver CD and a printed instruction manual. Take note that neither card includes any cables.
The PEXSAT34RH and PEXSAT34SFF are pretty similar for the most part. Both cards are based on Marvell's 88SE9230 chipset and are equipped with a PCI Express 2.0 connector. Aside from the type and number of ports, the most notable difference is the heatsink covering the 88SE9230 chipset on the PEXSAT34RH. I'm not really sure why the PEXSAT34SFF does not have a heatsink, but I'm guessing it has something to do with the location of the chipset and the size of the Mini SAS connector.
From the rear you can see the four SATA III (6Gbps) ports on the PEXSAT34RH as well as the Mini SAS (SFF-8087) connector on the PEXSAT34SFF. With its Port Multiplier feature, the PEXSAT34SFF lets you connect up to four SATA drives using a single breakout cable.
