Advantages Of Helical Scan In AIT Backup Tape

Majority of the current tape formats use the streaming drives. The data is read and written at a particular transfer speed. The performance of the tape drive is at its best when there is a reasonable match between the host and drive’s data rate. If the data rates do not match, then the tape drive will stop its operation, and will have to start again to match with the data stream. This repositioning will continue until the input/output task is finished or the tape media is full. As the difference among the data rates increases, there will be more time loss as the tape will have to reposition itself. This repositioning and start-stop dramatically lowers the performance and efficiency.

The reliability of the tape drive will also be effected as there will be additional stress and wear on the tape path, media and motors of the tape drive. Some of the tape drives will lower their speed so that they can match with the speed of incoming data. Compression techniques are employed by most of the drives, as the data rate of tape drive is multiplied by the compressibility factor. When the effectiveness of the tape medium is considered, then it is important that the gap of the compressed data rate must be evaluated.

AIT, QIC, SDLT, DLT, DAT72, Travan, DTF, DAT-160, 8mm tape, DDS, LTO and Enterprise tapes at discounted prices are available at Tape4backup dot com.

The Sony AIT 5 tape drive delivers outstanding performance and results against the different data compression levels and scales mostly at hundred percent of its rated performance. So the throughput capability of AIT-5 should be 256 GB/hour, for avg. 3:1 data compressibility ratio. Input/output throughput capabilities of the most branch office and SMB servers to tape drive lies in between the range of 150 to 200 GB/hour. 

AIT-5 tape technology’s helical-scan technique results in lower tape tension and power consumption with increased packing density. Single pass recording is enabled by the rotating head/drum assembly which is incorporated in a compact mechanism. Sony AIT 5 technology is very space efficient and is ideal for large libraries that comprise of hundreds of cartridges and many tape drives. Powerful and Innovative features of AIT tape technology ideally position it for SMB server environment’s archiving & data backup applications. Other large form enterprise tape formats cannot ideally match with rated speeds and data throughput of the SMB server environments, and these formats are more costly. 

Fast data access and native 400 gigabytes capacity of Sony SDX5-400C AIT-5 makes it perfect tape solution for SMBs. The results and performance of Sony AIT5 tape are far more superior and consistent in the SMB applications in comparison to other enterprise storage formats. The users of AIT-5 tape technology have the advantage of lower ownership cost and user-friendly backup solution. Sony SDX5-400W tape technology is very adaptable and has higher storage density. Sony maintains its leadership in the SMB and enterprise environments with its enhanced and efficient AIT tape products. The compatible autoloaders, tape drives and libraries of cost effective Sony AIT family provide the luxury and facility to the enterprises to expand and enhance their backup storage medium’s capabilities according to their needs.
