Dell CFM4W 1.92TB SSD SAS Mixed Use 24Gbps 2.5in SED SSD Overview

The Dell CFM4W 1.92TB SSD SAS Mixed Use 24Gbps 2.5-inch Self-Encrypting Drive (SED) is a high-performance enterprise-grade solid-state drive engineered to deliver a balance between endurance, reliability, speed, and data security. Designed specifically for Dell PowerEdge servers and enterprise storage systems, this SSD supports 24Gbps SAS interface technology, providing exceptional throughput for applications that demand consistent performance. Its 1.92TB capacity is ideal for organizations needing efficient storage without compromising performance or data protection. As a mixed-use drive, it accommodates both read- and write-intensive workloads, making it suitable for databases, virtualization, online transaction processing (OLTP), and other business-critical applications.

High-Speed SAS 24Gbps Performance

The integration of SAS 24Gbps technology gives the Dell CFM4W SSD a significant advantage over legacy SAS 12Gbps and SATA drives. With higher bandwidth and reduced latency, the drive ensures seamless data transfer even under demanding workloads. This speed translates to improved application responsiveness, reduced bottlenecks, and the ability to handle simultaneous requests in multi-user environments.

Enhanced Enterprise Throughput

• 24Gbps SAS interface doubles throughput compared to traditional SAS 12Gbps drives.
• High input/output operations per second (IOPS) ideal for databases and transaction-heavy workloads.
• Optimized for scalability in enterprise-class storage and compute infrastructures.

Reliability at Scale

Enterprise IT environments require storage solutions that can handle diverse workloads. The Dell CFM4W SSD ensures consistent low-latency performance with predictable response times, making it ideal for mission-critical deployments. With enterprise-grade firmware, it maintains stability under heavy I/O pressure.

Mixed Use Drive Capabilities

As a mixed-use SSD, the Dell CFM4W provides a balance between endurance and cost-effectiveness. Unlike read-intensive SSDs that favor sequential workloads or write-intensive SSDs focused on high endurance, mixed-use models like the CFM4W are optimized for versatile applications.

Workload Versatility

• Supports virtualized environments requiring high random read/write throughput.
• Efficient for both OLTP (Online Transaction Processing) and OLAP (Online Analytical Processing).
• Delivers sustained performance for hybrid workloads combining structured and unstructured data.

Endurance Optimization

Engineered with enterprise-grade NAND technology, the Dell CFM4W SSD offers reliable endurance metrics, ensuring longevity in environments where both read and write activities are frequent. Its write endurance is calculated to balance cost-effectiveness with reliability for enterprise-grade mixed workloads.

Data Security with Self-Encrypting Drive (SED)

Data security is a critical requirement in today’s IT landscape, and the Dell CFM4W SSD incorporates SED technology for robust protection. This ensures that sensitive enterprise data remains secure, compliant, and inaccessible to unauthorized users even if the drive is removed from the server.

SED Features

• Hardware-based encryption for minimal performance overhead.
• Meets compliance standards for data protection regulations.
• Supports secure erase functionality for safe decommissioning and re-provisioning.

Enterprise Security Benefits

The hardware encryption built into the CFM4W allows businesses to secure their data at rest without relying on software-based encryption, which can consume CPU resources. This makes it an efficient solution for businesses in regulated industries such as healthcare, finance, and government.
