Just How Consistent Is Pulsar XT.2’s Performance?

Just how consistent is Pulsar XT.2’s performance?  VERY – according to the “hot of the press” Storage Performance Council’s SPC-1C Puslar XT.2 performance test results for this ultra-fast enterprise, solid state drive (SSD).

SPC Key Performance Findings

The Storage Performance Council has independently confirmed Seagate’s performance specification claims for the Pulsar XT.2 SSD (they tested the 400GB, non-encrypting, 6Gb/s SAS model while in a steady state).  Pulsar XT.2 performed with impressive throughput numbers, achieving greater than 20K complex IOPS over a 4-hour sustained test period with a flat average response time of less than 3ms.

 

The linear user responsiveness (excursions
eliminated) and low latency with respect to
changing IO intensity levels are important
because this enables data centers  to meet
stringent service level agreement metrics
that demand the same level of reliable,
storage performance day in and day out,
24×7.

 

 

Seagate is the first (and so far) only HDD vendor to publish repeatable and reproducible SPC-1C enterprise SSD test results (using consistent test metrics).  We invite others in the industry to follow suit to enable customers to more easily compare products and make informed storage decisions.

(1)   The SPC-1C workload is comprised of a set of I/O operations that are designed to demonstrate the performance of a small storage subsystem while performing the typical functions of a mission critical application.  While enterprise workloads vary, the SPC-1C test uses synthesized scalable real world workloads that represent a segment of enterprise applications characterized by predominately random I/O operations and require both query and update operations (for example: OLTP systems, Database systems, and/or Mail Server applications).
