Sandisk announced that it has officially launched an innovative open source tool SPRandom, which solves major technical bottlenecks in SSD benchmark testing. Preprocessing is a key step in performance testing SSDs based on actual workloads.It can ensure the accuracy and repeatability of test results, and can truly reflect the performance of customers' actual use.
However, traditional preprocessing methods require long-term sequential and random writes to the SSD to bring large-capacity SSDs (especially those exceeding 16TB) into steady-state test conditions. This process often takes days or even weeks.
The SPRandom tool can significantly reduce preprocessing time from weeks to just hours by introducing a pseudo-random preprocessing algorithm and combining it with the commonly used I/O benchmark tool fio.Its core values are reflected in:
Significantly improve scalability: SPRandom effectively solves the problem of preprocessing time that increases sharply as SSD capacity increases. Taking a 32TB SSD as an example, the pre-processing time has been shortened from more than 160 hours to about 6.2 hours; for capacities of 64TB and above, the process that originally took weeks can now be completed in just a few hours.
Achieve industry breakthroughs: As an open source tool, SPRandom has good compatibility. It is not only suitable for SanDisk's own products, but also can be adapted to SSDs from other manufacturers, helping to promote the optimization of industry-wide testing standards.
Enhanced customer value: This tool not only saves customers a lot of test preparation time, but also ensures that users can obtain real and stable performance data from the initial stage to more accurately evaluate the performance of the product in actual applications.
The launch of SPRandom marks an important step towards making SSD benchmark testing more efficient, open and practical.
