A Suggestion of Disk Speed Test

The disk speed test duration lasts longer means it will calculate the speed benchmark more accurate, however, the developer won’t suggest you test too long to determine the hard disk.

He said even 15 seconds of Quick Test is enough for checking your hard disk is working correctly or not.

Though, Do Not test your hard disk frequently as it will reduce the lifetime of the disk.
