Samsung Unveils Ultra-fast 256GB SSD For Laptops


Samsung, the world's largest computer chip maker, said Monday it has developed a new 256MB solid-state drive which is expected to replace hard disk drives in laptop computers.

Samsung said its 256GB solid state drive (SSD) for data storage is 2.4 times faster than traditional hard drives. The company plans to begin production of SSDs this year.

The new SSD "represents a bold step in the shift to notebooks with significantly improved performance and larger storage capacities," the company said in a statement.

Samsung described the new SSD, 2.5 inches long and 9.5 millimeters thick, as the world's smallest of its kind. It can read up to 200 megabytes of data per second and write at a sequential write speed of 160MBps. For comparison, WD?s 300 GB Velociraptor 3.5" hard drive, which is considered the fastest traditional hard drive on the market today, achieves data read and write rates of just over 100 MB/s.

The multi-level cell (MLC)-based solid state drive (SSD) uses a SATA II interface. It boasts reliability equal to that of SLC SSDs, with a mean time between failures (MTBF) of one million hours, while costing considerably less. Power consumption is also very low at 0.9W in active mode. In addition, the drive offers a data encryption process that prevents data stored on the SSD from being accessed in an unauthorized manner, even after the SSD is removed from the PC.

It said, citing market research agency iSuppli, that 35 percent of notebook computers would use the SSD by 2012. Samsung has not provided pricing details. Currently available 256GB 2.5" SSDs cost more than $6,500, while WD?s Velociraptor hard drive sells for $300.



In related news, Samsung also said it developed a radio frequency chip, dubbed the "Mobile TV System-on-Chip" that single-handedly supports mobile television frequency standards in multiple regions, including South Korea, Japan, France and Germany.

The chip is even capable of relaying seamless mobile broadcasting in bullet trains travelling at 280 kilometers per hour, the company said, with production scheduled to begin in the third quarter.
