Once my manager asked me to transfer huge data files (up to 300GB) from the server to the external USB 2.0 hard drive, it took me hours to complete the task successfully. The reason why the data must be transferred to external disk was because the data must be copied to the mirror server in Sydney. It was in remote site where communication must be done via satellite. WAN link between remote sites to central office use satellite link with only 512 Kbps bandwidth.
Normally we use the autoloader tape backup as the central backup system for all the data servers. Autoloader tape backup solution is very advantageous for multi-server environment which reduces the overhead cost and time spent by the administrator to maintain the backup system. I didn’t copy the data on the backup tape, which must be easier and faster, because the backup cartridge used in remote site was not compatible with the mirror server in the head office. So, the solution was to transfer the data to the USB 2.0 external hard disk.
The maximum data transfer rate for USB 2.0 based adapter is around 480 Mbps. Actually this is a fast enough transfer rate for home usage. But for business environments where huge data backup / data transfer tasks frequently use USB external storage for some cases, the transfer rates of up to 480 Mbps (using USB 2.0 based device) is not fast enough to support your data copy tasks superslot. Today, you can use the Super Speed USB 3.0 for super speed data transfer rates of up to 5Gbps using USB 3.0 card adapters. With USB 3.0 card adapter, you can transfer your business data to the external USB 3.0 storage (such as Iomega eGo 2 TB USB 3.0 external hard drive) 10 times much faster than the speeds of USB 2.0 devices can transfer.
This type of USB 3.0 PCI express card adapter will only work on the computers / servers that support PCI Express slots. Peripheral Component Interconnect Express (PCI Express or PCI-E) is PCI which uses a much faster physical-layer communications protocol than traditional PCI bus architecture. PCI-E uses dedicated, unidirectional, point-to-point connections lanes to communicate with PCI Express devices.
The following are two types of USB 3.0 PCI-express card adapters you can use for your computers with PCI-express enabled.
TRENDnet 2-Port USB 3.0 PCI Express Adapter TU3-H2PIE
TU3-H2PIE is a USB 3.0 Card to add two super speed USB 3.0 ports to your desktop computers or servers with PCI Express enabled. It can support the super speed transfer rates of up to 5Gbps which is 10 times faster than traditional USB 2.0. The adapter is backward compatible with traditional USB 2.0 devices. It supports Windows 7 (32/64-bit), Windows Vista (32/64-bit), and Windows XP (32/64-bit).
Belkin SuperSpeed USB 3.0 PCI Express Card
Like Trendnet TU3-H2PIE, Belkin USB 3.0 Card adds two USB 3.0 ports to your desktop computers for super speed data rate transfers up to 5Gbps. It is also backward compatible with USB 2.0 devices. Belkin USB 3.0 can support computers with Windows XP; Windows Vista, and Windows 7 platforms.
USB 3.0 PCI adapter is a high speed data transfer rate solution for your business computers. But you can use the adapter only if your computers support the PCI Express slot. To obtain the maximum data transfer rates of up to 5Gbps, you need to connect the adapter to the same USB 3.0 devices such as Iomega eGo 2 TB USB 3.0 disk drives.
