Seagate introduced its first solid state disk, it's named Pulsar and it is aimed at the enterprise market. The Seagate Pulsar is a 2.5" SSD with SLC NAND flash memory, it is 7mm thick and you can get it with 50GB, 100GB or 200GB storage capacity.
The Pulsar series has a SATA 3Gbps interface and features sequential read speeds of up to 240MB/s and sequential write speeds of up to 220MB/s. The sustained write speeds are a lot lower though, the 200GB model is the fastest one with a sustained write speed of 160MB/s, while the 100GB model does 80MB/s and the 50GB model only 40MB/s. More specifications (including IOPS figures) can be found in this PDF file.
Designed for enterprise blade and general server applications, the Pulsar drive uses single-level cell (SLC) technology, delivers up to 200GB capacity, and is built in a 2.5-inch small form factor with a SATA interface. The Pulsar drive leverages Seagate’s 30 years of leadership in meeting large enterprise customer needs in product development, qualification, and support.
“Seagate is optimistic about the enterprise SSD opportunity and views the product category as enabling expansion of the overall storage market for both SSDs and HDDs,” said Dave Mosley, Seagate executive vice president, Sales, Marketing, and Product Line Management. “Our strategy is to provide our customers with the exact storage device they need for any application, regardless of the component technology used. We are delivering on that strategy with the Pulsar™ drive, and you can expect additional products in the future from Seagate using a variety of solid state and rotating media components.”
The Pulsar SSD delivers the necessary performance, reliability, and endurance to match the application environments of enterprise blade and general servers. It achieves a peak performance of up to 30,000 read IOPS and 25,000 write IOPS, 240MB/s sequential read and 200 MB/s sequential write. Its SLC-based design optimizes reliability and endurance and helps provide a .44% AFR rating with a 5-year limited warranty. As an additional safeguard, the Pulsar drive leverages Seagate’s enterprise storage expertise to protect against data loss in the event of power failure.
Seagate began shipping Pulsar units to select OEMs for revenue in September 2009. With Seagate’s enterprise knowledge and expertise, OEMs have peace of mind knowing that Seagate has the global enterprise systems, people and processes in place to support their largest requirements.
“To deliver and serve the enterprise SSD marketplace effectively, it is critical for suppliers to understand the needs of their storage system customers with respect to design, manufacturing, supply chain delivery, and support,” said Dave Reinsel, IDC group vice president. “With its well-established OEM and eco-system relationships and a long history of serving global storage OEMs, Seagate is in a unique position to fortify its leading enterprise storage position with its entry into the enterprise solid state storage market.”
