According to sources from hard disk manufacturers, Samsung’s HDD shipments are expected to surpass Toshiba in the second half of the year due to the strategy of bringing its own production of hard drives to IT products such as its notebooks.
Toshiba ranked fourth in HDD shipments in 2009 with a market share of 13.3%, lagging behind Seagate, Western Digital, and Hitachi. Samsung's HDD shipments in 2009 were only 51.64 million, with a share of 9.2%. However, according to statistics released by IDC in the first quarter of this year, Samsung HDD shipments have rapidly increased to 15.5 million units (share 9.5%), slightly behind Toshiba's 17.5 million units (share 10.7%).
Moreover, Samsung is also using its price strategy to obtain more orders from PC makers, and their hard disk shipment target this year is to double the base of 50 million last year to 100 million.
However, Toshiba also has confidence in the future shipments of hard drives. Although the demand for 1.8-inch hard drives is still declining, they believe that 2.5-inch hard drive shipments will see growth in the fourth quarter.
USB3.0 provides a standard interface for all kinds of devices that are connected to PCS or audio/high-frequency devices.The theoretical transmission speed is up to 5Gbps. HUB is commonly known as a hub, which is used to connect multiple computers or network devices in a network using a star topology. The USB 3.0 Hubs is an upgrade of the USB 2.0 Hubs. The transmission rate of the USB2.0 is 480Mbps, and the transmission rate of the USB3.0 is 5Gbps. The maximum transmission speed is 10 times that of the USB2.0, and the transmission speed is faster.
The USB 3.0 hub provides a quick and easy way to connect all the peripherals you use on your desktop. You can connect 2 external monitors, gigabit Ethernet ports, headphones/speakers, USB printers and scanners, keyboards, mice and other peripherals with a single USB 3.0 cable to your computer for up to 5Gbit/s external storage access (10 times faster than USB 2.0). USB HUBS can do split, but not evenly. If, as the subject says, you only have two devices, and the two devices are transmitting at the same time and taking up as much bandwidth as possible, then you end up with two devices each taking up 50% of the bandwidth. Due to the fast theoretical speed of USB3.0, even if divided into four parts, the theoretical bandwidth of each port is still as high as 1Gbps, and the number of converted bytes is close to 100MB/s, which is still a very high bandwidth.
