TK47C Dell 1.6TB SAS-24GBPS Mixed-Use TLC SFF SSD

Dell TK47C 1.6TB SAS-24GBPS SSD Overview

The Dell TK47C 1.6TB SAS-24Gbps solid state drive represents a purposeful convergence of performance, endurance, and compatibility for enterprise server environments. Built in a 2.5-inch small form factor and engineered for mixed-use workloads, the TK47C is designed to sit at the heart of scale-out systems, high-density racks, and blade servers where predictable latency, high IOPS, and consistent throughput are non-negotiable. With a SAS-24 GBPS interface and TLC 3D NAND technology, this model aims to serve as a dependable workhorse for virtualized environments, database clusters, and mixed read/write application stacks.

Small Form Factor

The compact 2.5-inch SFF design ensures the TK47C integrates cleanly into Dell EMC PowerEdge servers and other enterprise chassis built around hot-swap, high-density bays. The SFF footprint balances rack density and serviceability: administrators can scale storage capacity and performance without sacrificing drive replacement speed during maintenance windows. Because it conforms to the form factors commonly used in modern server fleets, the drive is widely compatible across generations of PowerEdge systems that accept SAS SFF drives, simplifying upgrade projects and reducing the operational complexity that often accompanies hardware refreshes.

Interface

SAS-24GBPS

The TK47C leverages a SAS 24 Gb/s interface to deliver a higher ceiling for sequential and random throughput compared with SATA-based enterprise SSDs. SAS provides enterprise-focused features such as dual-port connectivity on compatible controllers, advanced error handling and link-level integrity checks, and improved manageability for multi-drive configurations. In environments where multiple hosts or RAID controllers share high-demand storage pools, the SAS interface helps eliminate I/O bottlenecks and ensures that large sequential transfers and bursts of random I/O maintain consistent latencies. This is especially valuable for workloads that require low tail latency—such as OLTP databases, VDI farms, and latency-sensitive virtual machines.

Flash Technology

TLC 3D NAND

The TK47C uses modern TLC 3D NAND chemistry that balances cost per gigabyte with reliable endurance and performance tuning for enterprise loads. Manufacturers implement firmware strategies—such as advanced wear leveling, dynamic over-provisioning, and background garbage collection—to optimize TLC for consistent low-latency service across the device lifetime. These firmware features are tuned to reduce write amplification, manage thermal and performance throttling, and preserve sustained throughput during heavy mixed workloads. System architects can therefore expect a blend of efficient capacity economics and enterprise-grade longevity from the drive’s NAND and controller ecosystem.

Compatibility

The TK47C is marketed as Dell-certified for integration with PowerEdge server lines—including multiple generation variants—ensuring that the drive’s physical and firmware interfaces match system backplanes and RAID controllers. Integration with PowerEdge also means administrators can leverage native management frameworks such as iDRAC for monitoring drive health, updating firmware, and aligning replacement policies across a broad server estate. As with any enterprise component, verify part numbers and compatibility lists against the exact PowerEdge model and controller firmware versions to ensure plug-and-play operation.

Performance

Enterprise SSD performance depends on matching storage configuration parameters to real application I/O patterns. For OLTP systems and virtualized workloads, tuning queue depth and optimizing block size deliver lower latency and higher IOPS at the application layer. For analytics and large sequential workloads, ensuring that transfer sizes align with controller and drive cache characteristics maximizes sustained throughput. When possible, mirror production I/O during testing to identify optimal settings for RAID stripe width, file system allocation sizes, and caching policies. These low-level adjustments can yield large improvements in tail latency and delivery consistency for mixed-use drives like the TK47C.

Use Cases

The TK47C’s blend of high random IOPS and steady sequential throughput make it an excellent candidate for virtualization hosts and VDI infrastructure. The drive’s ability to handle frequent small-block reads and writes helps maintain responsive desktop sessions and rapid VM boot storms. When used as a tier within a hybrid storage architecture, the TK47C can accelerate active VM images while colder objects remain on high-capacity HDD tiers or object storage, offering an efficient balance between performance and cost. Capacity planning should consider IOPS per VM and expected working set sizes to avoid oversubscription of storage resources.
