Seagate (NASDAQ: STX) today began distribution channel shipments
of the Pulsar® XT.2 solid state drive (SSD) that combines
outstanding and consistent performance with the data integrity and
drive endurance needed for the most demanding enterprise
environments, and is on track to commence channel shipments of the
Pulsar.2™ SSD, the first Multi-Level Cell (MLC) Flash-enabled SSD
from an enterprise hard drive maker, on July 29.

The Pulsar XT.2 SSD combines Single-Level Cell (SLC) flash with
a native 6Gb/s Serial Attached SCSI (SAS) interface to make it the
fastest drive in the Seagate portfolio. The 2.5-inch SSD with up to
400GB of capacity is optimized for complex, mixed workloads typical
of enterprise environments such as online transaction processing
(OLTP), database or web indexing, and email.
The Pulsar.2 SSD has been designed specifically for data
centers, unlike typical MLC SSDs built for consumer applications,
which lack the robust data integrity and reliability required for
enterprise applications. The drive, featuring up to 800GB of
capacity, automatically detects and corrects any number of data
errors that could otherwise plague normal drive operations,
delivering the price/performance, data integrity, and endurance
needed for performance-hungry enterprise applications. The Pulsar.2
SSD supports both native 6Gb/s SAS and Serial ATA (SATA) 6Gb/s
interfaces for primary and secondary server storage.
“Most SSD suppliers aren’t fully aware of the needs of the
enterprise,” said Jim Handy of Objective Analysis. “It isn’t just a
fast interface like SAS, Fibre Channel, or PCIe that they need, and
it isn’t just IOPS levels in the tens to hundreds of thousands.
Without data integrity and reliability, an SSD is worthless to most
enterprise users. Seagate’s undeniable leadership in the enterprise
HDD market has given the company a deep understanding of the
necessity of data integrity and endurance.”
Pulsar® XT.2 Performance Validated by Industry-Standard
SPC-1C Result
The Pulsar XT.2 400GB SSD has met the rigorous standards of the
Storage Performance Council (SPC), a vendor-neutral consortium that
defines, administers and promotes industry-standard storage
benchmarks, for consistent and sustainable enterprise-class
performance. The new SPC-1C Result demonstrated that the Pulsar
XT.2 SSD delivers the sustainable storage device performance
enterprises need round-the-clock – regardless of the workload
complexity or changing server input-output (I/O) intensity
levels.
Fluctuating workloads, background media management and
program/erase functions can lead to erratic SSD performance,
compromising a data center’s ability to meet stringent
service-level agreements. These concerns can be alleviated by SSDs
that hold up under exacting performance tests requiring the devices
to sustain maximum I/Os for extended periods.
In a single storage device configuration, the Seagate Pulsar
XT.2 SSD produced an SPC-1C Result* of 20,008.82 SPC-1 IOPS with an
average response time of 2.05 milliseconds over a 10-minute
duration, compared to an SPC-1C Sustainability Test result of
20,011.07 IOPS with an average response time of 2.08 milliseconds
over four hours, demonstrating outstanding and consistent
enterprise-class performance over time.
The real-world SPC-1C benchmark, designed for storage
components, consists of I/O patterns typically found in online
transaction processing (OLTP) applications, with a focus on random
accesses. Unlike Iometer testing, which gauges IOPS performance
using discrete measurements of random reads, random writes,
sequential reads or sequential writes, SPC-1C benchmarks test
storage components using a dynamic blend of random and sequential
reads and writes to emulate real-world enterprise workloads.
Storage professionals worldwide view the SPC as the definitive
source for independent and verifiable comparisons of real-world
application performance.
As part of the SPC-1C Result, the Pulsar XT.2 SSD also met the
new SPC-1C requirement for data prefilling. Prefilling reduces any
potential performance gains storage component vendors may produce
by destroking a device, or limiting access to certain portions of
the storage space to artificially increase performance. Prefilling
writes random data to the entire addressable space of the
drive.
