Samsung MZWLO7T6HBLA-00A07 7.68TB PM1743 Enterprise NVMe SSD

Description

The Samsung MZWLO7T6HBLA-00A07 belongs to Samsung’s PM1743 enterprise SSD family, providing 7.68TB / 7,680GB of high-performance storage in a compact 2.5-inch enterprise form factor.

The PM1743 was designed around PCIe 5.0 to provide substantially higher storage bandwidth than previous-generation PCIe 4.0 enterprise SSDs. Samsung’s product specification lists the exact MZWLO7T6HBLA-00A07 configuration as a 2.5-inch PCIe 5.0 enterprise SSD with up to 14,000 MB/s sequential read and 6,000 MB/s sequential write performance.

The drive uses Samsung’s 128-layer V-NAND flash technology and is intended for demanding enterprise environments such as AI/ML, databases, high-performance storage, and virtualized infrastructure.

Key Specifications

The performance and interface specifications above are based primarily on Samsung’s PM1743 documentation and current exact-SKU product listings.

7.68TB Enterprise Storage Capacity

The MZWLO7T6HBLA-00A07 provides 7.68TB of enterprise storage capacity, making it suitable for large datasets and high-performance server applications.

Samsung’s PM1743 datasheet lists the 7.68TB model with 15,002,931,888 addressable sectors. Samsung notes that the stated capacity represents usable SSD capacity and that the actual capacity presented to an operating system may vary due to storage management and formatting.

Typical applications include:

• Enterprise databases
• AI and machine-learning infrastructure
• Virtualization
• Cloud computing
• High-performance computing
• Data analytics
• Enterprise storage
• Application servers
• Large-scale content repositories
• Data-center workloads

PCIe 5.0 Enterprise Performance

The PM1743 is designed to take advantage of PCIe 5.0 bandwidth.

For the exact 7.68TB model, Samsung specifies:

• Sequential Read: Up to 14,000 MB/s
• Sequential Write: Up to 6,000 MB/s
• Random 4KB Read: Up to 2,500K IOPS
• Random 4KB Write: Up to 300K IOPS

These figures represent maximum specified performance under Samsung’s test conditions. Actual results depend on the server platform, PCIe topology, firmware, workload, queue depth, thermal conditions, operating system, and storage configuration.

Samsung V-NAND Technology

The PM1743 uses Samsung’s V-NAND flash technology and is designed specifically for high-performance enterprise environments.

Current product documentation identifies the PM1743 as using 128-layer V-NAND, providing the flash architecture required for high-density enterprise storage and sustained performance.

Enterprise Endurance

The 7.68TB PM1743 is positioned as an enterprise SSD with a 1 DWPD endurance class.

For the 7.68TB configuration, this corresponds to approximately 14,016TBW over a five-year endurance period when calculated at one full drive write per day.

This endurance profile makes the SSD appropriate for demanding applications including:

• Databases
• Virtualization
• AI/ML workloads
• Cloud infrastructure
• Enterprise applications
• Data analytics
• High-performance storage
• Mission-critical server workloads

2.5-Inch Enterprise Form Factor

The MZWLO7T6HBLA-00A07 uses a 2.5-inch enterprise SSD form factor.

This allows it to integrate into compatible enterprise servers and storage platforms designed for PCIe/NVMe 2.5-inch SSDs.

Important: A standard 2.5-inch drive bay does not automatically guarantee compatibility. The server must provide the appropriate PCIe/NVMe backplane, connector, firmware support, and PCIe lane configuration.

Enterprise Reliability

The PM1743 is designed for continuous operation in enterprise and data-center environments.

Published specifications for this model include an MTBF of approximately 2.5 million hours, while the drive’s enterprise endurance and data-integrity features are designed for sustained professional workloads.

The SSD is appropriate for environments where high availability, high throughput, and predictable storage performance are important.

AI, Machine Learning & High-Performance Computing

The combination of 7.68TB capacity, PCIe 5.0 bandwidth, and multi-million-IOPS random-read performance makes the PM1743 particularly suitable for data-intensive workloads.

Potential applications include:

• AI model data storage
• Machine-learning datasets
• GPU server storage
• High-performance computing
• Large database systems
• Real-time analytics
• High-speed scratch storage
• Data-intensive virtualization

Enterprise Database Applications

High random-read performance and PCIe 5.0 bandwidth can benefit database environments that require rapid access to large numbers of small data blocks.

Suitable workloads include:

• OLTP databases
• Analytics databases
• Data warehouses
• Transaction processing
• Application databases
• High-performance database caching

Actual database performance will depend on the database engine, server CPU, memory, workload pattern, and storage software.

Virtualization & Cloud Infrastructure

The PM1743 can provide high-speed storage for virtualization environments where multiple virtual machines generate simultaneous I/O traffic.

The combination of high sequential throughput and high random-read performance can support:

• Virtual machine storage
• Hypervisor infrastructure
• Private cloud platforms
• Container environments
• Application clusters
• Cloud-native workloads

The exact server and hypervisor must support the drive’s PCIe/NVMe configuration.

Compatibility Considerations

Before installation, verify that the target server or storage system supports:

• PCIe 5.0 NVMe SSDs
• 2.5-inch enterprise NVMe drives
• The required PCIe lane configuration
• Compatible NVMe backplane
• Appropriate U.2/U.3 or enterprise connector configuration
• Server BIOS/UEFI NVMe support
• Compatible firmware
• Operating-system NVMe support
• Adequate cooling and airflow

The MZWLO7T6HBLA-00A07 should not be treated as a conventional SATA SSD.

It is also not an M.2 SSD.

PCIe Generation Compatibility

The PM1743 is designed for PCIe 5.0 operation.

For maximum performance, the host platform should provide the appropriate PCIe 5.0 implementation and lane configuration.

Installing the drive in an older PCIe-generation environment may reduce performance and may require specific platform support. Always verify the server’s validated SSD compatibility list before installation.

Important Interface Note

There are conflicting third-party listings regarding whether this exact SKU is described as U.2 or U.3 and whether the PCIe connection is presented as x4 or x8. Samsung’s own enterprise product table identifies MZWLO7T6HBLA-00A07/00B07 as a 2.5-inch PCIe 5.0 x8 drive, while other current retailers market the same SKU as a U.2/U.3 PCIe 5.0 SSD.

For a store listing, I recommend using the conservative wording:

2.5-inch PCIe 5.0 enterprise NVMe SSD

and verifying the exact backplane/connector requirement against the target server.
