PCIe SATA cards advertise 6 Gb/s per SATA port, but that is a per-link signaling rate, not guaranteed aggregate throughput. Controller chipset, PCIe lane width, port multipliers, boot support, operating-system drivers and whether the card is true hardware RAID all matter. Avoid counting the same unbranded PCB under several marketplace names.

Buying tips
- Check the exact chipset and board revision before ordering.
- SATA III is 6 Gb/s per port; the PCIe uplink is shared.
- Most low-cost cards provide AHCI/pass-through, not true hardware RAID.
- Confirm boot support and drivers for your operating system.
