SEAGATE, CHANNEL SHIPMENTS OF THE PULSAR XT.2 SOLID STATE DRIVE (SSD)
http://dervishcom.blogspot.com/2011/07/seagate-channel-shipments-of-pulsar-xt2.html
Seagate currently began placement channel shipments of a Pulsar XT.2 plain state drive (SSD) that combines outstand-ing and- unchanging opening with a interpretation firmness and- expostulate continuation indispensable for a many demand-ing craving environments, and- is upon lane to embark channel shipments of a Pulsar.2 SSD, a initial Multi-Level Cell (MLC) Flash-enabled SSD from an craving tough expostulate maker, upon Jul 29.

The Pulsar XT.2 SSD combines Single-Level Cell (SLC) peep with a local 6Gb/s Serial Attached SCSI (SAS) interface to have it a fastest expostulate in a Seagate portfolio. The 2.5-inch SSD with up to 400GB of genius is optimized for complex, churned workloads standard of craving environments such as online contract estimate (OLTP), database or web indexing, and- email.
The Pulsar.2 SSD has been written privately for interpretation centers, distinct standard MLC SSDs built for consumer applications, that miss a strong interpretation firmness and- trustworthiness compulsory for craving applications. The drive, featuring up to 800GB of capacity, automatically detects and- corrects any series of interpretation errors that could differently disease normal expostulate operations, delivering a price/performance, interpretation integrity, and- continuation indispensable for performance-hungry craving applications. The Pulsar.2 SSD supports both local 6Gb/s SAS and- Serial ATA (SATA) 6Gb/s interfaces for first and- delegate server storage.
"Most SSD suppliers aren't entirely wakeful of a needs of a enterprise," pronounced Jim Hand-y of Objective Analysis. "It isn't only a quick interface similar to SAS, Fibre Channel, or PCIe that they need, and- it isn't only IOPS levels in a tens to hundreds of thousand-s. Without interpretation firmness and- reliability, an SSD is meaningless to many craving use-rs. Seagate's definite care in a craving HDD marketplace has since a association a low understand-ing of a prerequisite of interpretation firmness and- endurance."
Pulsar XT.2 Performance Validated by Industry-Stand-ard SPC-1C Result
The Pulsar XT.2 400GB SSD has met a severe stand-ards of a Storage Performance Council (SPC), a vendor-neutral consortium that defines, administers and- promotes industry-stand-ard storage benchmarks, for unchanging and- tolerable enterprise-class performance. The new- SPC-1C Result demonstrated that a Pulsar XT.2 SSD delivers a tolerable storage device opening enterprises need round-the-clock – in any case of a effort complexity or becoming different server input-output (I/O) power levels.
Fluctuating workloads, credentials media government and- program/erase functions can lead to haphazard SSD performance, compromising a interpretation center's capability to encounter difficult service-level agreements. These concerns can be alleviated by SSDs that reason up underneath harsh opening tests requiring a inclination to means limit I/Os for lengthened periods.
In a singular storage device configuration, a Seagate Pulsar XT.2 SSD constructed an SPC-1C Result* of 20,008.82 SPC-1 IOPS with an normal reply time of 2.05 milliseconds over a 10-minute duration, compared to an SPC-1C Sustainability Test outcome of 20,011.07 IOPS with an normal reply time of 2.08 milliseconds over 4 hours, demonstrating outstand-ing and- unchanging enterprise-class opening over time.
The real-world SPC-1C benchmark, written for storage components, consists of I/O patterns typically found in online contract estimate (OLTP) applications, with a concentration upon rand-om accesses. Unlike Iometer testing, that gauges IOPS opening regulating dissimilar measurements of rand-om reads, rand-om writes, consecutive reads or consecutive writes, SPC-1C benchmarks exam storage components regulating a energetic mix of rand-om and- consecutive reads and- writes to obey real-world craving workloads. Storage professionals worldwide perspective a SPC as a decisive source for eccentric and- verifiable comparisons of real-world focus performance.
As partial of a SPC-1C Result, a Pulsar XT.2 SSD additionally met a new- SPC-1C order for interpretation prefilling. Prefilling reduces any intensity opening gains storage member vendors might furnish by destroking a device, or tying entrance to sure portions of a storage space to artificially enlarge performance. Prefilling writes rand-om interpretation to a complete addressable space of a drive.
