3.84TB Enterprise Storage Capacity

The 3.84TB capacity provides substantial high-speed storage for enterprise systems where performance, reliability, and predictable storage behavior are important.

The drive is suitable for workloads including:

• Enterprise databases
• Virtualization
• Cloud infrastructure
• Storage arrays
• Application servers
• Transaction processing
• Data analytics
• Enterprise file services
• High-performance computing
• Data-center applications

The actual usable capacity available to the operating system or storage array can be lower than the manufacturer-rated capacity due to formatting and system overhead.

SAS 12Gb/s Interface

The MZILT3T8HBLS-00007 uses a 12Gb/s SAS interface.

SAS is an enterprise storage interface designed for servers, storage arrays, and data-center infrastructure. SAS platforms can provide features such as enterprise controller compatibility, multi-device storage architectures, and redundant storage configurations.

The exact model is identified in Samsung’s product information as:

SAS 12.0 Gbps / 2.5-inch / 3.84TB.

Important

This drive is not an NVMe SSD.

It should be connected to a compatible SAS HBA, RAID controller, SAS backplane, or enterprise storage enclosure.

Sequential Performance

The PM1643a 3.84TB model provides high sequential storage throughput.

Published specifications for the exact MZILT3T8HBLS-00007 identify:

• Sequential Read: Up to 2,100 MB/s
• Sequential Write: Up to 2,000 MB/s

These performance figures are suitable for workloads involving large sequential transfers such as databases, enterprise storage, virtualization, analytics, and large-scale data processing.

Actual performance depends on the SAS controller, server platform, workload characteristics, queue depth, RAID configuration, firmware, and operating environment.

Random I/O Performance

For workloads involving numerous small and simultaneous storage operations, the drive provides strong random-access performance.

Published specifications list:

• Random Read: Up to 450,000 IOPS
• Random Write: Up to 90,000 IOPS

This makes the SSD suitable for demanding applications such as:

• Database workloads
• Virtual machines
• Transaction processing
• Enterprise applications
• Metadata-intensive storage
• Multi-user environments
• Online services

Samsung V-NAND Technology

The PM1643a uses Samsung’s 3D V-NAND flash technology.

V-NAND provides the flash storage foundation for the PM1643a enterprise SSD family, allowing Samsung to combine high storage density with enterprise-oriented performance and endurance characteristics.

Enterprise Endurance

The MZILT3T8HBLS-00007 is specified with an endurance rating of approximately:

1 DWPD for 5 years

DWPD, or Drive Writes Per Day, indicates how much of the drive’s rated capacity can be written each day over the specified endurance period under the manufacturer’s qualification methodology.

This makes the drive appropriate for enterprise environments experiencing sustained storage activity.

Typical workloads include:

• Databases
• Virtualization
• Enterprise applications
• Storage arrays
• Cloud infrastructure
• Analytics
• Data-center services

Published product specifications identify the exact model with 1.0 DWPD over 5 years.

Enterprise Reliability

The PM1643a is designed for continuous enterprise operation.

Published specifications identify:

• MTBF: 2,000,000 hours
• Endurance: 1 DWPD for 5 years
• Power-Loss Protection: Yes
• Operating Temperature: 0°C to 70°C
• Storage Temperature: -40°C to 85°C

The enterprise-oriented design makes the drive suitable for systems where storage availability and data integrity are important.

Power-Loss Protection

The MZILT3T8HBLS-00007 incorporates Power-Loss Protection (PLP).

PLP is designed to help protect data and maintain storage integrity during unexpected power interruptions by providing the SSD with the necessary protection to complete critical internal operations.

This is particularly valuable in:

• Enterprise servers
• Database systems
• Storage arrays
• Virtualization infrastructure
• Mission-critical applications

The exact model is listed with Power Loss Protection in published specifications.

Enterprise Security

The PM1643a supports enterprise-oriented storage security features.

Published information for this model identifies TCG Enterprise security support, while Samsung’s PM1643a documentation covers enterprise security capabilities for the product family.

These features are intended for environments requiring stronger protection of data stored on enterprise storage devices.

2.5-Inch Enterprise Form Factor

The MZILT3T8HBLS-00007 uses a standard 2.5-inch enterprise SSD form factor.

Published dimensions are approximately:

• Length: 100.5 mm
• Width: 69.85 mm
• Height: 7 mm
• Weight: Approximately 100g

However, physical 2.5-inch dimensions alone do not guarantee compatibility. The server or storage enclosure must provide a compatible SAS backplane and controller.

Server & Storage Applications

The Samsung PM1643a MZILT3T8HBLS-00007 is designed for enterprise storage environments.

Recommended applications include:

Enterprise Servers

• Database servers
• Application servers
• Virtualization hosts
• Enterprise file servers

Storage Systems

• 12Gb/s SAS
• 2.5-inch enterprise drives
• A compatible SAS controller or HBA
• A compatible SAS backplane
• The required server firmware
• Appropriate RAID/storage-management software where applicable

The drive should not be marketed as a SATA or NVMe SSD.

SAS vs SATA vs NVMe

Technology	MZILT3T8HBLS-00007
SATA	❌ No
NVMe	❌ No
PCIe	❌ No
SAS	✅ Yes
SAS Speed	12Gb/s
Form Factor	2.5-inch

SAS Storage Architecture

SAS is commonly deployed in enterprise environments where multiple drives are connected through SAS controllers and backplanes.

The MZILT3T8HBLS-00007 can therefore be used as part of compatible:

• RAID arrays
• Enterprise storage servers
• SAS JBOD systems
• SAN environments
• High-availability storage configurations

Actual RAID functionality depends on the server’s RAID controller or storage platform rather than the SSD itself.

Thermal & Environmental Specifications

The drive is specified for an operating temperature range of:

0°C to 70°C

The specified storage temperature range is:

-40°C to 85°C

Adequate server airflow should be maintained, particularly in high-density drive configurations and sustained workloads.
