En este Post describiremos algunos de los aspectos más destacados del nuevo estándar de comunicaciones para dispositivos USB, el USB 3.0
La principal característica es que la velocidad o tasa de transferencia se multiplica por 10 con respecto al anterior estándar, pasando de los actuales 480 Mbps del USB 2.0 a los 4,8 Gbps (600 MB/s).
Hard disk systems have recently encounted a storage density ceiling. Most methods in use today have a limit of a few hundred gigabytes per square inch thanks to perpendicular recording. To try to keep storage density rising, scientists have looked at technologies from holographic storage to molecular polymers, but few have made it past the demonstration stage. In a paper in Nature Photonics this week, researchers describe a way to combine two hard drive writing methods to store data at densities of up to one terabit per square inch, and suggest the media could be stable up to ten terabits per square inch.
