Overview

The Dell PERC H740P Mini-Card RAID Controller is built for enterprise storage environments where data integrity and throughput are non-negotiable. Connecting via a PCI Express 3.1 x8 bus, it delivers 12Gb/s SAS performance while also supporting 6Gb/s SATA drives, giving administrators flexibility in their choice of storage media. The controller supports RAID levels 0, 1, 5, 6 as well as spanned configurations 10, 50, and 60, enabling everything from maximum-performance striping to multi-parity fault tolerance depending on the workload requirements.

A defining feature of the H740P is its 8GB nonvolatile cache, which accelerates read and write operations while safeguarding in-flight data during unexpected power events—no separate battery backup unit is required. The mini-card form factor is designed to install directly into compatible Dell PowerEdge server motherboards, conserving valuable expansion slot real estate. With 8 SAS ports and Dell's proven PERC firmware, this controller is a dependable foundation for servers running database workloads, virtualization hosts, file storage, and other I/O-intensive applications that demand consistent performance and robust data protection.

Pros & Cons

👍 Pros

  • 8GB nonvolatile cache preserves write data during power loss without needing a separate battery backup
  • Supports RAID 0, 1, 5, 6, 10, 50, and 60 for flexible data protection and performance tuning
  • 12Gb/s SAS interface provides high throughput for demanding storage workloads
  • Mini-card form factor fits directly into Dell PowerEdge servers without occupying a full-height expansion slot

👎 Cons

  • Designed specifically for Dell PowerEdge servers and is not compatible with third-party or consumer systems
  • 8 SAS ports may be limiting for high-density storage configurations requiring many drives
  • PCI Express 3.1 interface, while performant, does not take advantage of newer PCIe 4.0 bandwidth
  • Premium pricing compared to lower-tier PERC controllers that may suffice for lighter workloads

Frequently Asked Questions

It supports RAID 0, 1, 5, 6, 10, 50, and 60, covering a wide range of performance and redundancy configurations.
The PERC H740P uses nonvolatile cache, meaning the data in cache is preserved during a power loss without requiring a separate battery backup unit.
The controller supports 12Gb/s SAS and 6Gb/s SATA drives, but SAS and SATA drives should not be mixed within the same RAID virtual disk for optimal performance and compatibility.
It connects via a PCI Express 3.1 x8 slot in supported Dell PowerEdge server platforms.
The controller provides 8 total SAS ports for connecting storage drives.
