345-BKRT Dell 1.92TB SATA-6GBPS Mixed Use 2.5-Inch Hot Plug SSD

Outline of Dell 345-BKRT 1.92TB SATA MU SSD  

The Dell 345-BKRT 1.92TB is a high-performance 2.5-inch SATA solid state drive engineered for mixed-use enterprise workloads. With a SATA-6Gbps interface and a 3 drive writes per day (3DWPD) endurance rating, this drive combines high capacity with durability and predictable performance for virtualization, database, and general-purpose server storage. The hot-plug 2.5-inch form factor ensures easy field replacement and compatibility with a wide range of Dell PowerEdge servers and storage enclosures.

Performance Characteristics

The Dell 345-BKRT is tuned to deliver consistent IOPS and throughput at SATA-limited bandwidth. While NVMe drives offer lower latency, SATA SSDs like the 345-BKRT remain a cost-effective solution for many enterprise deployments where predictable performance, compatibility, and capacity per dollar matter. This drive provides strong sustained sequential throughput and solid random I/O handling for mixed workloads.

Read and Write Behavior

For mixed-use SSDs, performance is defined by both steady-state write latency and read throughput. The 345-BKRT typically provides:

High sequential read speeds that approach the SATA-6Gbps theoretical ceiling.Solid sequential write performance suitable for large file transfers and backups.
Robust random read/write IOPS for concurrent virtual machines and database operations.

Sustained Throughput and QoS

Mixed-use drives are engineered for quality-of-service (QoS) — predictable latency under steady-state conditions. When deployed in RAID arrays or with proper caching layers, the 345-BKRT helps maintain consistent application responsiveness even during heavy, multi-tenant workloads.

Reliability, Endurance & Data Integrity

Enterprise SSDs must maintain data integrity and predictable lifespan. The 3DWPD rating (Drive Writes Per Day) means the drive can sustain writing an amount equal to its capacity three times daily across its warranted life — a balance between cost and durability for mixed workloads.

Endurance Explained (3DWPD)

Endurance is a critical spec for SSD selection. 3DWPD at 1.92TB equates to a total terabytes written (TBW) across the warranty period: multiply the drive capacity, DWPD, and warranty period to estimate TBW. For mixed-use scenarios, this endurance rating is generally sufficient for virtualization hosts, distributed file systems, and application servers where write intensity is moderate.

Power Loss Protection & Data Safeguards

Enterprise-class drives such as the 345-BKRT usually incorporate firmware features and hardware safeguards to protect data in transit from buffer to NAND during unexpected power events. These protections reduce the risk of metadata corruption and improve the probability of successful recovery after an unclean shutdown.

Compatibility  

One of the strengths of SATA-based enterprise SSDs is broad hardware compatibility. The Dell 345-BKRT 1.92TB SSD is designed to be compatible with a large range of Dell PowerEdge servers, RAID controllers, and storage shelves that support 2.5-inch SATA drives.

Server and Storage Appliance Fit

Typical integration scenarios include:

Primary or secondary storage within PowerEdge servers for virtual machine (VM) storage.Boot drives or cache tiers for hyperconverged infrastructure (HCI) where SATA is supported.
High-capacity arrays where cost-per-GB matters more than absolute low latency.

Controller and Firmware Considerations

Ensure that server firmware, RAID controller firmware, and storage OS drivers are up to date. Proper firmware alignment between host and drive can affect performance, power management, and feature availability (e.g., TRIM support, SMART reporting). Dell validated combinations provide the most reliable experience.

Hot-Plug Serviceability

The hot-plug 2.5-inch form allows quick field replacement without shutting down servers in many architectures. This reduces maintenance windows and simplifies drive upgrades or replacements in production environments.

The Dell 345-BKRT

Selecting the right SSD depends on workload profile, required endurance, latency sensitivity, and budget. The 345-BKRT is ideal for environments that require a blend of capacity, endurance, and value.

Virtualized Environments

Virtualization platforms (VMware ESXi, Microsoft Hyper-V, KVM) that host many small-to-medium VMs benefit from mixed-use SSDs. The 1.92TB capacity lets administrators consolidate VM storage while the 3DWPD endurance supports daily write activity across multiple tenants.

Transactional Workloads

OLTP databases and caching layers often generate random I/O. Mixed-use SSDs deliver a reliable combination of random IOPS and sequential speeds, making them suitable for mid-tier database workloads where latency caps are moderate.

Content Delivery and Media Workflows

For media transcoding, streaming caches, or content delivery nodes where large files are read frequently and occasional writes occur, a SATA mixed-use SSD with 1.92TB capacity provides a balance of storage density and throughput.

Mixed-Use SATA SSD vs. Other Storage Options

Selecting between mixed-use SATA SSDs, read-intensive SSDs, and NVMe SSDs depends on workload and budget. Below is a comparative overview to aid decision-making.

Mixed-Use SATA vs. Read-Intensive SATA

Endurance: Mixed-use typically offers higher DWPD than read-intensive models, making them better for write-heavy mixed workloads.
Cost per GB: Read-intensive drives may be less expensive per GB but unsuitable for heavy write environments.

Mixed-Use SATA vs. NVMe SSDs

Latency & IOPS: NVMe provides significantly lower latency and higher IOPS for latency-sensitive applications.
Compatibility & Cost: SATA SSDs like the 345-BKRT are more widely compatible with legacy systems and often offer a lower cost per GB for larger capacities.
