Toshiba's GX7 Series PWM adjustable speed drive is a severe duty drive package built to handle all conventional applications in the industry, ranging from the simplest to the most complex. The GX7 Series offers flux-vector technology with or without encoder feedback. This drive maintains astoundingly tight control over both torque and speed with the industry's most user-friendly operator interface. The write access test, however, is done with a 1 GB big test file.The GX7 is designed to handle the most extreme conditions, continuing the G-Series tradition of delivering a robust performance platform.
Finally the access time of the SSD is calculated, wherein the access to read over the entire capacity of the SSD (Full Stroke) is determined. In the first three synthetic tests and the compression test, the size of the test file 1 GB. This is especially for the controllers that use to increase the performance and life of the cell compression, important. The additional compression test can measure the power of the SSD in response to compressibility of the data. This test should SSDs pose with Native Command Queuing (NCQ), differences between the IDE operation mode where NCQ is not supported, and the AHCI mode. The 4K-64 corresponds to the test Thrd 4K procedure except that the read and write operations are distributed to 64 threads. 4K test the read and write performance is determined at random 4K blocks. In Seq-test the program measures how long it takes to read a 1 GB file to write respectively.
These tests are carried out without using the operating system cache. The synthetic tests determine the sequential and random read and write performance of the SSD. Two extra benchmark tests examine the drive's behaviour when copying a few big files, a lot of small files and a mixture of file sizes by using cached copy functions of your OS as well as reading/writing data depending on the data's compressibility. Additionally, it performs the tests using 1 or 64 threads and it determines the SSD's access time. AS SSD Benchmark reads/writes a 1 GByte file as well as randomly chosen 4K blocks. Test the sequential or random read/write performance without using the cache.
