  • Humidity : 10% to 80% (Non-Condensing)
Available Models

With Big IDE 4-pin Power Connector

With SATA 15-pin Power Connector

Without Power Connector
Without Power Connector
Computer Platform
  • Computer with PCI Express slot (x1, x4, x8, x16)

For the best performance (5.0 Gbps), It should be installed in a PCIe Gen 2 compliant slot in the host computer.  Most computers have PCIe Gen 2 (5.0 Gbps) throughput on x8 or x16 slots.
A PCIe Gen 1 compliant slot reaches up to 2.5 Gbps throughput
