SSD Poised to Become Drive of Choice in 2010

SSD-logoLSI Corp. and Seagate Technology Inc. recently announced their collaboration to create a PCI-based Solid State Drive (SSD). The companies are combining LSI’s board-level product integrating SAS and PCIe technology with Seagate’s SSD technology to address consumer demands for increased speed and power by achieving new levels of performance, reliability and ease of use. For the computer industry, it looks increasingly likely that SSD technology will begin to phase out Hard Disk Drives (HDDs).

HDD performance has inherent physical limitations. Data transfer rates are defined by the speed of the spindle motor, which controls and spins the platters that hold the computer data. An additional disadvantage of HDDs is the high power consumption of the spindle motor and its required set of heating and cooling devices. Finally, data access for HDD relies on the synchronization of the electromagnetic read/write devices and the platters, which can limit random access speeds. SSDs, on the other hand, are built entirely out of semiconductors and require no moving parts. Storage is handled by flash memory chips rather than magnetic media. An SSD is able to provide a more rugged and portable computing experience with reduced power consumption, higher reliability and faster data access.

New technologies are highlighting the limitations of HDDs, especially with transfer speeds. For example, SuperSpeed USB (USB 3.0) has the capacity to transfer data at 5Gb/s, which is a faster rate than a HDD can transfer. Because SuperSpeed USB exceeds the speed of a HDD, consumers using a product with a HDD will not be able to take full advantage of this new technology’s data transfer rate capabilities. With new innovative technologies and the demand for increased bandwidth, the SSD is suited to be the drive of choice for manufacturers.

The Solid State Drive Alliance (SSDA) has authorized Allion as its first SSD Independent Testing Lab (ITL) for the SSDA Compliance Program. With emerging technologies creating a greater consumer demand for speed and reliability, 2010 could be the year for the SSD.
