Dell 6K35K 1.92TB SAS 24GBPS Solid State Drives

The Dell 6K35K 1.92TB SAS 24Gbps Read Intensive TLC solid state drive is engineered to deliver a balanced blend of high sustained throughput, low latency, and predictable performance for read-dominant enterprise workloads. Designed as a SFF 2.5-inch form factor drive with 24Gb/s SAS connectivity, this 1.92TB module targets Dell EMC PowerEdge 14g, 15g and 16g server platforms and storage arrays that require compact, hot-pluggable, rack-optimized storage. The drive’s Read Intensive TLC NAND and a rated 1 DWPD (drive writes per day) endurance class make it ideal for workloads where heavy read activity, consistent response times, and cost-efficient capacity are priorities. When paired with Dell EMC PowerEdge hardware, the 6K35K delivers predictable latency and strong sustained read throughput for virtualization, database read replicas, distributed file systems, and large-scale content repositories.

Key technical characteristics and what they mean for your environment

This Dell-certified SSD combines a 1.92TB usable capacity in a small 2.5-inch SFF package with enterprise-grade SAS 24Gb/s interface speed, which supports high-speed server backplanes and storage controllers on modern PowerEdge systems. The drive’s Read Intensive TLC flash media trades off slightly lower program/erase endurance for a much lower cost per gigabyte versus write-intensive classes while preserving read performance and data reliability. The 1 DWPD rating indicates that the drive is designed for scenarios where writes are relatively light compared to reads, making it a cost-effective choice for read-heavy virtualization tiers, operating system volumes, analytics query nodes, and cache tiers where capacity and read throughput matter more than high write endurance. Enterprise-grade features such as power-loss protection circuitry, robust error-correcting code (ECC), advanced wear-leveling algorithms, and TLER-like firmware behaviors ensure data integrity and predictable drive behavior under demanding server use.

Compatibility with Dell EMC PowerEdge 14g / 15g / 16g

The Dell 6K35K 1.92TB SAS SSD is certified for use in Dell EMC PowerEdge 14th, 15th, and 16th generation servers, meaning it has been validated at the firmware and hardware levels to work with the storage backplanes, RAID controllers, and management tools typical of those platforms. This certification reduces integration risk and simplifies lifecycle management because firmware updates, secure erase operations, and SMART monitoring are supported through Dell OpenManage and the server’s integrated management controller. Administrators benefit from seamless hot-swap insertion and removal, consistent reporting of health metrics, and compatibility with existing RAID and HBA configurations. In clustered and hyperconverged architectures that rely on predictable drive behavior during rebuilds and failure scenarios, having a Dell-certified SSD reduces the chance of anomalies and simplifies vendor support.

Performance profile: latency, throughput, and sustained reads

Read-intensive SSDs like the 6K35K are optimized to deliver low read latency across a wide range of I/O sizes and access patterns. While peak sequential throughput on SAS 24Gb/s depends on controller and backplane tuning, the drive is designed to sustain high read IOPS and consistent latency for small random read workloads typical of VDI boot storms, database index lookups, metadata operations, and file-server reads. The TLC flash is paired with enterprise firmware that prioritizes read caching and garbage collection scheduling to minimize latency jitter during steady-state operations. For environments that demand consistent sub-millisecond response times for reads under multi-tenant load, the 6K35K’s architecture provides a high probability of meeting service level objectives while offering a favorable capacity-to-cost ratio.

Endurance, reliability, and data protection

Although this model is categorized as Read Intensive with 1 DWPD endurance, it still incorporates multiple reliability features found in enterprise drives. Power-loss protection mechanisms protect in-flight metadata, reducing the risk of corruption from unexpected power events. Strong ECC and RAID-aware firmware help prevent silent data corruption by detecting and correcting errors before they surface to the operating system. Wear-leveling algorithms distribute program/erase cycles evenly across the NAND to extend usable life, and SMART telemetry exposes critical health information for proactive replacement. Administrators can rely on these capabilities to keep read-dominant storage tiers in service longer while reacting to early warning signs when necessary. For mission-critical data where higher write endurance is required, these drives can be complemented by higher-DWPD modules in mixed-tiered storage configurations to balance endurance and cost.

Use cases where the Dell 6K35K shines

This SSD is purpose-built for read-centric enterprise tasks. In virtual desktop infrastructure (VDI) deployments, the drive’s fast read performance accelerates boot storms and application launches, improving end-user experience without excessive cost. Analytics clusters and data warehouses benefit from quick access to indexes and reference tables, lowering query latency for ad-hoc and business intelligence workloads. Content delivery and media repositories that require high read throughput for streaming and file access can use the 1.92TB capacity to consolidate more content in fast storage, reducing the need for network-bound retrievals. Additionally, as a read-optimized tier in hybrid storage architectures, the 6K35K provides the high-performance read layer while write-heavy activity is funneled to write-intensive drives or NVMe caches, offering a robust multi-tier strategy for cost-efficient performance.

Tiered storage strategies and hybrid deployment patterns

Modern data centers often adopt a tiered model in which workloads are matched to storage classes according to performance and endurance needs. In this context, the Dell 6K35K functions effectively as a midline read tier, positioned between high-end NVMe or write-intensive SAS SSDs and bulk HDD capacity. Data that demands low-latency reads but does not see many writes—such as replicated database read-only instances, large index partitions, frequently accessed VM templates, and content caches—can be placed on this 1.92TB SAS SSD to accelerate access while keeping costs down. Hybrid arrays and hyperconverged infrastructures use such drives for read acceleration, while write buffering or journaling is offloaded to higher-DWPD devices. This approach maximizes overall system efficiency and cost-effectiveness while preserving predictable service behavior during peak read loads.

Operational benefits: management, maintenance, and lifecycle

Because the 6K35K is Dell-certified, lifecycle tasks such as firmware updates, health monitoring, and end-of-life planning integrate with standard Dell tooling, including OpenManage Enterprise and iDRAC. This integration simplifies operational workflows and reduces the administrative overhead of managing a heterogeneous drive fleet. SMART attributes, predictive failure alerts, and standardized reporting help data center operators schedule maintenance windows and replacements before failures impact applications. The hot-plug 2.5-inch form factor enables rapid swaps in dense server environments without downtime for many configurations, and certified compatibility reduces the frequency of unexpected incompatibilities with subsequent generations of server firmware. From procurement through retirement, the drive’s certification and telemetry support a predictable lifecycle strategy that aligns with enterprise maintenance policies.

Security and compliance considerations

Enterprise deployments must consider data security and regulatory compliance. The Dell 6K35K supports common enterprise security features such as hardware-based encryption and secure erase commands. When used in conjunction with controller-level encryption or self-encrypting drive (SED) frameworks, the SSD can help organizations implement data-at-rest protections required by industry regulations. Secure sanitize and crypto-erase features enable rapid decommissioning of drives while meeting strict data removal policies. For environments governed by compliance frameworks that mandate auditable data destruction, encrypted drives reduce the administrative complexity of physical destruction by allowing cryptographic erasure to be used as part of standard retirement workflows.

Capacity planning and cost-efficiency

When sizing storage for read-heavy tiers, the 1.92TB capacity per drive offers an attractive balance of density and cost. Consolidating more read-hot datasets onto fewer drives reduces rack space, power consumption, and cabling complexity while lowering the number of spindles that need to be managed. Because TLC-based read-intensive SSDs have a lower cost per gigabyte relative to higher endurance variants, organizations can expand fast storage capacity with less capital outlay. This economical capacity makes the 6K35K attractive for service providers and enterprises seeking to increase performance without dramatic increases in acquisition cost. Total cost of ownership analysis should account for the drive’s endurance class and pair it with workload profiling to avoid overexposure of write-intensive workloads to read-optimized media.

Best practices for deployment and configuration

To get the best results from Dell 6K35K SSDs, administrators should profile workload I/O patterns and establish placement policies that reflect the drive’s read-optimized nature. Use these drives for read-heavy volumes and consider RAID configurations that maximize read availability, such as RAID 10 or RAID 6 with sufficient parity design for expected rebuild times. Pair read-intensive drives with appropriate write buffers or use NVMe caching where write bursts may occur to protect the SSDs from unnecessary wear. Regularly monitor SMART and firmware-level metrics through Dell OpenManage and set thresholds for predictive replacement. Finally, ensure that firmware versions remain current and validated for the deployed Dell PowerEdge generation to benefit from performance optimizations and reliability improvements.
