I am trying to compare performance of several hard drives in my current system, and downloaded performance test 9.0 to try to run some comparisons. Things were going well until I ran the test on a 1TB western digital drive, and I am having a hard time believing the results, and now they are all suspect in my mind. This is the specs for the drive I have run multiple tests, with different file sizes and I am consistently get over 700MB/Sec for the read tests. I can't believe that is true, so im assuming something is off with the tests, but the results for my other drives look correct/reasonable. PerformanceTest Results can be seen So, one just to make sure im not loosing my mind, there isn't a cache system, of anything that could make these results legit right? Assuming thats the case, can anyone recommend a good performance test tool for testing hard drives? Since the question was unclear I was looking for two things. A sanity check that I wasn't over looking something stupid that could be cause the test to be skewed. A good way to preform a general performance test against multiple drives to compare the drives against each other. I believe you are looking at a drive whose firmware has been written to detect benchmark tests and cheat in various ways. (Yes, drive manufacturers have done that.) Try an ordinary real-world test, like copy a large file to the drive, then shut down and power down (to clear OS and drive caches), then copy it back to another place on the origin drive. Certainly something is off. The specs for that drive have it at only SATA 3 Gb/s, which is 300 MB/s (that's at the SATA connector and is the maximum burst speed possible between drive cache and the motherboard interface - never mind actually reading and writing the media). 700 MB/s would be over twice that fast! And the 'internal data rate' (that's between the media and the drive internal cache) is only 111 MB/s! Quickbooks license and product number keygenguru.

HD Tune Pro is a hard disk / SSD utility with many functions. It can be used to measure the drive's performance, scan for errors, check the health status (S.M.A.R.T.). ![]() So clearly a measurement of 700 MB/s cannot be correct. There is a mistake somewhere. Maybe several somewheres. In contrast, little is graceful and daddy is not dear in Julien’s world. He wears gold teeth. Julien is different, schizophrenic. Anvil’s Storage Utilities For an SSD or hard drive benchmark and test utility that really puts drives through their paces, they don’t come much more comprehensive than Anvil’s Storage Utilities. While being able to perform a complete read and write test using sequential and random operations, it displays a full set of results including response time, speed in MB/s and also IOPS. A total overall score is in the yellow box. Also included are 3 extra IOPS tests, an endurance testing function and the ability in the settings to alter the amount of compression to use on the test file. More functions like a system information tab and a screenshot saver round off an impressive tool. Anvil’s Storage Utilities is not a final build yet and currently at the Release Candidate stage. Disk Thruput Tester DiskTT is a small and portable testing tool that uses Windows core read and write functions to write a temporary file to the specified drive, then read it back sequentially and randomly to get three resulting scores.
