Adds six SATA 3.0 ports at 6.0 Gbps via a PCIe x4 slot, includes cables and a low-profile bracket
The RIITOP PCES36P+CB adds six SATA 3.0 ports through a single PCIe x4 slot. It is aimed at builders who need more internal drive connections for storage arrays or backup drives. The card uses the ASMedia ASM1166 chipset and provides AHCI support without RAID functionality.
Six SATA 3.0 cables ship in the box so every port can be populated immediately. A low-profile bracket is also supplied, allowing the card to fit in slim or half-height chassis where a full-height bracket would not clear the case.
Installation needs a free PCIe x4 or larger slot; the card will not work in an x1 slot. The controller cannot boot an operating system drive, so it is only suitable for additional data drives. Drivers are native to modern operating systems, and the single-chip design avoids extra configuration steps.

The ASM1166 uses native AHCI support in Windows and Linux so no separate driver is required and firmware updates are not typically issued for this controller.
The PCI Express 3.0 x4 host link caps aggregate bandwidth at roughly 4 GB/s so the bus saturates before the individual 6.0 Gbps ports do.
The single ASM1166 chip runs passively with no onboard fan and the low-profile bracket fits tight airflow paths without adding audible noise.
