XceedIOPS SATA SSD

Smart Modular Technologies Inc. rolls the XceedIOPS SATA, its next-generation enterprise-class solid-state drive (SSD). Available in 1.8- and 2.5-inch form factors, the device comes with either single-level cell (SLC) or enterprise-grade multi-level cell (E-MLC) NAND technologies.

The XceedIOPS SATA SSD is the second product in SMART's XceedIOPS family, and the first SSD from SMART to feature the SF-1500 processor from SandForce Inc. The XceedIOPS SATA is the industry's first SSD to integrate E-MLC technology, which provides significantly more endurance than SSDs based on commercial MLC NAND flash.

Endurance for E-MLC is specified at 20,000 program/erase (P/E) cycles, whereas current generation commercial MLC demonstrates 1,500 or 5,000 P/E cycles, depending on the NAND flash vendor. The combination of the SF-1500 processor's minimal write amplification and E-MLC flash enables the XceedIOPS SATA SSD to handle the most demanding enterprise workloads. For example, a 5-year lifetime can be easily achieved with a 400Gbyte XceedIOPS SATA in an environment that demands 250MBps sustained write and a 40 percent duty cycle.

"Enterprise storage and server system OEMs are looking for SSDs that provide improved performance, reduced total cost of ownership, and high reliability," said Jeff Janukowicz, research manager, HDD components and SSDs at IDC. "SSDs like the new XceedIOPS SATA from SMART that meet these requirements and leverage enterprise-grade MLC and controllers, like the SandForce processor, will help to accelerate the adoption of SSD technology in the enterprise."

Featuring a SATA 2.6 interface and support for native command queuing, the 1.8- and 2.5-inch SSDs are optimized for high performance of up to 30K IOPS random read/write, 250MBps sustained read/write; and high capacity of up to 400Gbyte. High reliability is achieved through flash management techniques such as power and data fail protection, data path protection, and an enhanced error correction code engine.

Because of its high random read/write performance, a single XceedIOPS SATA can replace several HDDs, thus saving space, improving reliability, and reducing power use. In fact, the 1.8-inch form factor SSD was specifically designed for space-constrained blade server and high-density computing applications.

"The enterprise SSD market appears to be entering a period of impressive growth. Well-positioned to satisfy the requirements of enterprise deployments, we expect our XceedIOPS SATA SSDs will provide low cost, superior performance, low power, and high capacity flexibility," said Alan Gulachenski, VP and general manager, enterprise solid state storage, Smart.

The XceedIOPS SATA SSDs are sampling this month to strategic customers, with production quantities scheduled for Q2 10.
