SATA & eSATA PCI-X RAID Controllers

Below is a more in-depth comparison of our SATA and eSATA PCI-X controllers.
note: All PCI-X controllers will also work in a PCI slot.

PCI-X SATA Multilane Controllers

Areca and HighPoint controllers are performance leaders in this category. The controllers using SFF-8470 can connect to our external enclosures with 4x cables. The controllers using SFF-8087 can connect to our external enclosures with internal/external adapters.

If you are not worried about RAID performance or if you need non-RAID hotswapping, Silicon Image provides a cost-effective solution.

PCI-X SATA Controllers

These controllers primarily feature discreet SATA connectors. While they are often used internally, they can also be converted for external use with adapters. Areca provides higher performance hardware RAID while HighPoint provides lower cost options.

PCI-X eSATA Controllers

The Silicon Image controller enables expansion beyond 4 drives via eSATA port multipliers, and PC PitStop has one of the largest selections of high-quality port multiplier enclosures.
