Benchmark Test Description
Hard Drive Benchmark results (“Baselines”) were gathered from users’ submissions to the PassMark web site as well as from internal testing. PerformanceTest conducts three different tests and then averages the results together to determine the PassMark Disk Mark rating for a system... [ Read the entire article ]

Assasin's Creed: Valhalla PC graphics performance review and analysis. It's a bit of a feast for the eyes; yes, we'll check it out in a PC graphics performance and PC gamer way. Olivia Rodrigo took part in a virtual interview about 'Drivers License' that included a performance of the hit song - one that was just Rodrigo, her keyboard and all her emotions.
Rarely is a graph completely accurate in what it is representing. There are many factors that can skew the results and make a graph misleading. As such it is necessary to have some background understanding of the data being presented.
In the case of these Hard Drive Benchmarks there are several factors to consider, such as different system setups the Hard Drives are running under and how fragmented the drives file system is.... [ Learn more about the graphs ]

How to Add Your Own Hard Drive
Download and install PerformanceTest.
Start PerformanceTest then from the menu bar select 'Tests->Run All Tests'.
Once the tests have run select 'Baseline->Upload Baseline to Web'.
Your results will not appear in the graphs immediately as the graphs are only updated once per day. Additionally, only Hard Drives of which there are at least three samples are included in the graphs.

Test the sequential or random read/write performance without using the cache. AS SSD Benchmark reads/writes a 1 GByte file as well as randomly chosen 4K blocks. Additionally, it performs the tests using 1 or 64 threads and it determines the SSD's access time.
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.
The synthetic tests determine the sequential and random read and write performance of the SSD. These tests are carried out without using the operating system cache. In Seq-test the program measures how long it takes to read a 1 GB file to write respectively. 4K test the read and write performance is determined at random 4K blocks. The 4K-64 corresponds to the test Thrd 4K procedure except that the read and write operations are distributed to 64 threads. 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 additional compression test can measure the power of the SSD in response to compressibility of the data. This is especially for the controllers that use to increase the performance and life of the cell compression, important.
In the first three synthetic tests and the compression test, the size of the test file 1 GB. 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. The write access test, however, is done with a 1 GB big test file.
What's New:
- NVMe SSD support
- 4K LBA sectors support
- At least .NET Framework 4.6 required
- Increased accuracy for fast SSDs
