September 29, 2009 -- At the recent Intel Developer Forum 2009 in San Francisco, the Serial ATA International Organization (SATA-IO), the consortium dedicated to the dissemination of serial ATA (SATA) technology, announced that it is developing a specification for a mini-SATA (mSATA) interface connector. The new low-profile connector will enable more effective SATA integration in small form factor applications, says the consortium.
According to SATA-IO , the mSATA technology leverages the speed and reliability of the SATA interface to provide a high-performance, cost-effective storage solution for smaller devices like notebooks and netbooks. The specification maps SATA signals onto an existing small form factor connector, enabling more compact integration in a wide variety of applications for both hard disk (HDD) and solid state drives (SSDs). The mSATA connector allows companies to increase the storage offerings of their products without compromising valuable space, maintains the consortium.
mSATA is particularly beneficial for manufacturers planning to incorporate small form factor SSDs (approximately the size of a business card) in portable PC devices, where space utilization and cost minimization are key concerns.
"As consumers become more reliant on mobile devices, it makes sense to bring the efficiency and speed of SATA technology to this burgeoning highly portable product segment," comments Knut Grimsrud, SATA-IO president and Intel fellow and director of storage architecture. "Solid-state drives provide a rugged, lightweight and lower power storage solution for these devices, and mSATA is one of the few interfaces that can provide a critical compact connection for these small-form factor SSDs."
mSATA will support 1.5 Gb/s and 3.0 Gb/s transfer rates.
"SATA is already the predominant storage interface used in the hard disk drive (HDD) market," says Jeff Janukowicz, research manager for Solid State Drives at technology consulting firm IDC. "The mSATA specification extends the low-cost, high-speed benefits to the rapidly growing SSD market, increasing the options for manufacturers to develop small form factor solutions."
Development of the mSATA specification is being driven by members of the SATA-IO Cable and Connector Working Group, including Dell, HP, Lenovo, Samsung, SanDisk, STEC and Toshiba.
"SSD technology can work inside of virtually any form factor, so the new SATA specification should go a long way in encouraging extremely compact SSD storage designs," comments Jim Elliott, vice president, memory marketing, Samsung Semiconductor, Inc. "Highly compact Samsung SSDs are perfectly suited as a cost-efficient storage medium for the growing slim notebook marketplace, particularly netbooks."
"One of the key values SSDs enable is smaller form factors that allow both notebook and netbook computers to be lighter, thinner and more stylish," adds Don Barnetson, sr. director of marketing for SanDisk. "SanDisk is pleased to support the mSATA form factor as part of our leading pSSD product line which will be on display at the SATA-IO booth at the upcoming IDF."
"Initial adoption of most SATA solid state drives has followed the HDD form factor. Using new mSATA modules enable a smaller, internal module connected to the system board for notebooks, mobile and other embedded storage applications to enable designers greater design flexibility," concludes Scott Nelson, VP memory, Toshiba America Electronic Components, Inc. "Toshiba is introducing mSATA modules using 32nm NAND in 30 and 62GB densities with read speeds of 180MB/s and write speeds of 50MB/s."
