eShinreal PCIe x1 to 8 Port SATA 6Gb/s SAS/SATA Expansion Card

This PCIe x1 to 8-Port SATA/SAS expansion card is designed to add high-capacity storage connectivity to systems with limited onboard SATA ports. By leveraging a single PCIe x1 slot, it provides eight independent SATA III (6Gbps) ports, with some models also supporting SAS drives for enterprise environments.

Key Features &

Specifications

1. High-Density Storage Expansion
Adds 8x SATA III (6Gbps) ports via a single PCIe x1 slot (mechanical x1, may require x4 electrical for full performance)

Supports both SATA HDDs/SSDs and SAS drives (SAS support depends on controller, e. g., LSI 9211-8i)

Mini-SAS (SFF-8087) connectors on some models (allowing 4x SATA/SAS drives per connector)

2. Bandwidth & Performance
PCIe 2.0 x1: ~500MB/s shared bandwidth (can bottleneck multiple drives under heavy load)

PCIe 3.0 x1: ~985MB/s improves throughput but may still limit 8x SSDs at full speed

Best for:

Light-to-moderate workloads (NAS, backup arrays)

Staggered access (not all drives active simultaneously)
