Seagate Pulsar® XT.2 Solid State Drives Review

• Seagate Pulsar® XT.2 Solid State Drives Review

This review is about one of the Seagate Pulsar products, namely the Seagate Pulsar® XT.2 Solid State Drives, which are available in capacities of either 100GB, 200GB or 400GB, with a 6GB/s SAS interface, along with the Encryption option.

Below is some information about the available models :-

• Model ST400FX0012 | 6-Gb/s SAS | 400 GB | Encryption
• Model ST200FX0002 | 6-Gb/s SAS | 200 GB | None
• Model ST100FX0002 | 6-Gb/s SAS | 100 GB | None

The Seagate® Pulsar® XT.2 drive is a 2.5-inch, 6Gb/s SAS, up to 400GB, enterprise solid state drive (SSD). This SSD delivers the highest levels of performance, data integrity and drive endurance for the most demanding enterprise environments.

Seagate Pulsar® XT.2 Solid State Drives Overview

Data centers need to store and deliver the highest-value data quickly, consistently and reliably. The Pulsar XT.2 SSD was designed for the enterprise and provides the ultra-fast speed and highest endurance that write-intensive, Tier 0 applications need.

Key Features and Benefits

• Consistent high performance for complex, I/O intensive, mixed workload enterprise environments
• Fastest random write performance available in a small form factor, SAS-based SSD (18% higher than the closest competitor)
• Ultra-high endurance (supports over 35 full drive writes per day (25 petabytes written lifetime)
• Advanced media-management technology helps protect against unexpected data change or loss
• 6Gb/s SAS interface for scalability and reliability
• 2.5-inch form factor fits existing HDD slots
• Hotpluggable to avoid unnecessary downtime
• Common storage foundation reduces system complexity and operating overhead
• World-class service, fulfillment and reliability
• Self-Encrypting Drive (SED) option helps companies be compliant with data security mandates and helps protect data at rest throughout the life of the storage device*

* Self-Encrypting Drive models not available in all countries or capacities. Requires TCG-compliant host or controller support.


Best-Fit Applications

• Tier 0, external storage arrays
• Performance-hungry, write-intensive enterprise applications
• Blade servers, general servers and direct-attached storage (DAS) solutions that crave the advantages of solid state technology
• Enterprise architectures that use auto-tiering solutions

Consistent, Fast Performance
Data centers need to store and deliver the highest value data quickly, consistently and reliably. The Pulsar XT.2 SSD was designed for complex, mixed workload enterprise environments. It performs background data and media management tasks without impacting end-user performance. The drive delivers the fastest random write performance available in a small form factor, SAS-based SSD, the best balance of random read to random write performance, and the speed that write-intensive, Tier 0 applications need while minimizing time variance between read and write operations.

Enterprise Class Endurance and Data Integrity
The Pulsar XT.2 SSD can routinely complete over 35 full drive writes per day (up to 25 petabytes written over the life of the device), providing the endurance needed in demanding enterprise environments. It uses advanced media-management techniques to help protect against unexpected data change or loss. It also uses media scanning helps protect against read disturb data errors, and protection information helps ensure data is not unintentionally changed throughout its lifecycle. Power-loss data protection helps ensure data is not lost or inadvertently changed during power loss, and advanced wear-leveling algorithms evenly write across all NAND blocks to maximize the life of the SSD.


Scalability and Reduced System Complexity
The Pulsar XT.2 SSD uses the industry-standard SAS interface to improve scalability and to avoid software stack compatibility issues It also uses standard 2.5-inch form factors that hot swap into existing HDD slots to avoid chassis, ecosystem changes and downtime.

World-Class Service and Support
Seagate has the global presence and enterprise storage ecosystem customer relationships, systems, people and processes to consistently deliver the industry’s highest-quality products and support.
