IRVINE, Calif. -- Targeting high-transaction, write-intensive workloads, such as data and online transaction processing, Toshiba introduced an enterprise solid-state drive (eSSD) with a serial attached SCSI (SAS) interface and layered error correction code (ECC). The PX02SS, announced on October 28, has 100 GB to 800 GB of storage and is based on 24nm enterprise MLC (eMLC) NAND flash memory.
“SAS SSDs provide the best combination of capacity, performance, manageability and scalability for enterprise storage applications,” Kent Kubota, product marketing manager in Toshiba’s Enterprise SSDs, Storage Products business unit, told EE Times.
According to the press materials, the PX02SS runs at 12 Gb/s, and gives 30 full drive writes per day. Its data retention is three months with power removed. Some models have self-encrypting technology but all share a common architecture and controller design.
Toshiba designs the SSD’s components, such as the NAND flash, controller, and firmware, and manufactures the NAND memory. But, in a market where SSDs seem to have a “me too” quality, what makes this drive unique? Toshiba’s Kubota says that a common architecture and controller design among all the Toshiba eSSDs is a selling point. “Toshiba offers a range models including the ‘write-intensive’ PX02SS enterprise-grade SSD that are based on a common architecture and controller design. Architecture commonality helps to reduce qualification risk for our customers.”
Obviously the common architecture and components have advantages for Toshiba: “[It] simplifies the design and qualification process for Toshiba in addition to greater scale in materials procurement,” said Kubota. “One of the biggest technical challenges for enterprise SSDs is the balance of cost and reliability of NAND flash memory and the associated SSD controller technology required to take advantage of lower cost NAND.”
As SSD matures and NAND flash gets cheaper, Kubota predicts a tipping point when “the value proposition of SSDs will become even more apparent in system architecture. Our customers can expect a complete eSSD product line-up from Toshiba. Our goal is to be a complete enterprise storage solution provider,” he said.
The PX02SS SSD is available now.
