TYPW4 Dell 1.6TB SAS-24GBPS ISE Mixed-Use 512e SFF Hot-Plug

Dell TYPW4 1.6TB SSD Overview

The Dell TYPW4 1.6TB solid state drive represents a targeted solution for modern PowerEdge server environments that require a balance of sustained performance, endurance for mixed-use workloads, and platform-level compatibility with Gen14–Gen16 server families. Engineered as a 2.5-inch small form factor hot-plug module and supplied with the OEM tray for direct installation into Dell PowerEdge drive bays, this model is purpose-built for database acceleration, virtual machine density, and general-purpose consolidated storage tiers within data centers. The TYPW4 drives utilize a SAS interface capable of up to 24Gbps throughput, delivering predictable, low-latency I/O for enterprise applications and clustered storage pools.

Key Technical

At its core, the TYPW4 SKU denotes Dell's factory-configured 1.6TB capacity option built to the ISE mixed-use specification with 512e sector emulation and a rated write endurance suitable for balanced read/write workloads. The drive typically appears in Dell part listings and channel catalogs as a 1.6TB SAS Mixed-Use SSD with 3 drive writes per day endurance class, reflecting its design point between read-intensive and heavy mixed-use enterprise tiers.

Performance

The performance profile of the TYPW4 is optimized for workloads that need consistent IOPS under mixed access patterns. The SAS 24Gbps physical layer reduces queuing and bottlenecks in multi-threaded server databases and hyperconverged platforms, while internal NAND and controller firmware are tuned for I/O determinism and background maintenance tasks such as wear leveling and garbage collection. This drive is well suited for consolidated virtualization hosts, multi-tenant database instances, and hybrid caching tiers where sustained throughput, predictable latency, and moderate endurance are required. Because the drive implements enterprise-grade features—such as power-loss protection and enterprise-class error correction—it fits into mission-critical environments where reliability and data integrity cannot be compromised.

Form Factor

The TYPW4 is delivered as a 2.5-inch SFF module and commonly shipped with the Dell drive tray that fits PowerEdge front bays, enabling tool-less hot-swap serviceability and straightforward replacement procedures during maintenance windows. This OEM tray compatibility eliminates many of the physical integration challenges faced when installing third-party drives into branded servers. Field documentation and reseller listings consistently show the TYPW4 as compatible with numerous PowerEdge models across multiple generations, making it a practical choice for environments that standardize on Dell hardware and require consistent spares and upgrade paths. When planning an upgrade or refurbishment, administrators should reference platform support matrices and firmware compatibility notes, but in typical deployments the TYPW4 installs as a native SAS device and is recognized by iDRAC and the server's RAID or HBA controllers.

Endurance

Endurance metrics for mixed-use SSDs like the TYPW4 are balanced to meet real-world data center needs: the drive’s 3DWPD-class endurance allows frequent writes while still offering the read performance required by analytics and virtualization. Error correction, enterprise SMART reporting, and onboard power-loss safeguards all contribute to a drive that is reliable over sustained duty cycles. For environments employing RAID, erasure coding, or software-defined storage layers, the consistency of SMART telemetry and vendor-provided diagnostics simplifies fleet management and capacity planning.

Choose a SAS-24GBPS

Selecting a SAS 24Gbps interface for mixed-use drives bridges performance and connectivity needs in enterprise racks where legacy SAS infrastructures coexist with the latest server backplanes. The higher link rate provides headroom for sequential transfers, snapshot restores, and large-scale data migration tasks without saturating the bus. Additionally, SAS retains enterprise-level manageability, multipath options, and predictable behavior under load that SATA often cannot match in multi-controller topologies. This makes the TYPW4 especially attractive for deployments that rely on server-side RAID or hardware HBA configurations and that expect sustained multi-client access patterns.

Integration

For administrators managing firmware baselines and lifecycle updates, the TYPW4 behaves like a standard OEM Dell SSD: firmware updates are typically published via Dell's support channels and can be applied through iDRAC or vendor management suites. Because enterprise storage firmware changes can affect performance and interoperability, following vendor guidance for firmware and controller compatibility is recommended. Keeping a consistent fleet of identical SKUs such as TYPW4 across a cluster reduces the risk of incompatibilities and simplifies spares logistics. When procuring these drives, buyers often receive product listings that include Dell part numbers and order codes to ensure the correct firmware family and warranty registration.

Capacity

Choosing a 1.6TB capacity point like the TYPW4 involves weighing usable capacity, endurance class, and cost per gigabyte against application requirements. In consolidated hosts where multiple VMs share underlying storage, a higher-capacity SSD reduces the number of drive slots consumed while providing sufficient headroom for snapshots and ephemeral workloads. When measuring total cost of ownership, include the benefits of reduced power and cooling relative to HDD tiers as well as the operational advantages of faster rebuilds and easier drive failover during maintenance. Procurement teams frequently compare the TYPW4’s price and warranty terms against alternative capacity points and endurance classes to determine the ideal mix of cost, capacity, and resilience for their estate.

Compatibility

Before adding TYPW4 drives to a configuration, system administrators should confirm a short compatibility checklist: verify server model support (generation and chassis), confirm controller or HBA compatibility with SAS 24Gbps, reconcile tray and caddy types for the target PowerEdge model, check firmware families for cross-compatibility, and ensure that warranty and support terms meet organizational standards. Resellers and channel distributors often provide explicit compatibility matrices listing PowerEdge R350/R450/R550 families through R750/R760 models and selected tower or dense compute platforms. Matching the physical tray and connector type is particularly important to avoid mechanical mismatches that could complicate hot-swap operations.
