LSI RocketRAID 2744 16-Port PCIe 2.0 x16 SAS/SATA RAID Controller

SKU CH-XW7K-EB8SN

Adds 16 SAS/SATA ports with 600 MB/s throughput and RAID 0, 1, 5, 10, 50 via PCIe 2.0 x16

  • 6 Gb/s throughput for fast storage arrays
  • 16 SAS/SATA ports via four Mini-SAS connectors
  • PCIe 2.0 x16 host interface for broad server compatibility
  • RAID 0, 1, 5, 10, 50 and JBOD for flexible data protection
  • Windows, Linux, FreeBSD and macOS 10.7 Lion driver support

16-Port SAS/SATA RAID Controller

The HighPoint RocketRAID 2744 provides sixteen internal drive connections through four external Mini-SAS ports using a PCI-Express 2.0 x16 host interface. It targets storage builders who need hardware RAID 0, 1, 5, 10, 50 or JBOD across many SATA or SAS drives in a single full-height slot.

Bandwidth ceiling

Each port delivers a 6 Gb/s link, giving a 600 MB/s per-drive maximum that the PCIe 2.0 x16 bus can saturate only when multiple drives are active simultaneously. Total array throughput is therefore limited by the sixteen-lane generation-2 link rather than the individual drive links.

RAID 50 support

The firmware includes RAID 50, allowing striped parity sets across all sixteen ports for capacity and redundancy in one volume. Buyers who need RAID 6 or triple-parity protection must select a different controller.

Questions about this item

Should I pick the 16-port RocketRAID 2744 or the 2722 for my build?

The 2744 provides 16 ports across four external Mini-SAS connectors, while the 2722 is a different model with fewer ports. Choose the 2744 when you need to attach up to 16 SAS or SATA drives through the four Mini-SAS links.

What does the 600 MB/s transfer rate mean once the card is installed?

Each of the 16 ports can move data at up to 600 MB/s over a 6 Gb/s SAS or SATA link. The PCIe 2.0 x16 host bus supplies enough aggregate bandwidth so the controller does not throttle individual drive performance.

Which interface standard does the PCIe 2.0 x16 slot cap in practice?

The card plugs into a PCIe 2.0 x16 slot and presents four external Mini-SAS ports. Each Mini-SAS port carries four 6 Gb/s lanes, so the slot’s 8 GB/s ceiling is not reached by the 16 combined 6 Gb/s device links.
