Toshiba T6UG1XBG Performance

The ATTO Disk Benchmark 2.34 program measures interface transfer rates at various intervals for a user-specified length and then reports read and write speeds for these spot-tests. ATTO Disk Benchmark requires that an active partition be set on the drive being tested, and for testing purposes we format using NTFS after SSD partition alignment. The charted results illustrate bandwidth speed using various file size chunks, and can be used as a general performance indicator.


HD Tune is a low-level test that will not operate on a drive which contains a partition, so Benchmark Reviews uses DISKPART to prepare hardware and remove any partitions before conducting these tests. Random Access tests are divided into 512b, 4KB, 64KB, 1MB and random size test files sizes. The Random Access test measures the performance of random read or write operations. The amount of data which will be read varies from 512 bytes to 1 MB. Performance is reported in operations per second (IOPS), average access time, and average speed. Because it is our intent to compare one product against another, Benchmark Reviews has focused on random transfer size IOPS performance.


Using DISKPART with the clean all command to align the Kingston SSDNow V+ SNVP325, ATTO reported a maximum read-speed of 238 MBps and a respectable 188 MBps write performance. These results are better than Kingston's stated maximum speed of 230/180MBps. For operational input/output, HD Tune reports 4855 IOPS for 4KB reads and 2583 IOPS for write-to operations. At this level of I/O performance, the Toshiba T6UG1XBG SSD processor is best suited for high-performance consumer environments (notebook/desktop).


In the coming months, Benchmark Reviews will test several new Solid State Drive products based on Toshiba T6UG1XBG SSD processor. Our first is the Kingston SSDNow V+ SNVP325 MLC SSD used for testing in this article. Our entire collection of SSD articles is available in the Benchmark Reviews Featured Reviews: Storage section.
