Despite not quite matching write performance claims, the P41 still manages to turn in chart-topping sequential write performance, and is very close to the same on reads. The Platinum P41 manages to exceed its rated sequential read speeds by a fair margin, but does not quite match its rated write speeds. SK hynix Platinum P41 1TB CrystalDiskMark 1GB SK hynix Platinum P41 1TB CrystalDiskMark 1GB Chart CrystalDiskMark 圆4ĬrystalDiskMark is used as a basic starting point for benchmarks as it is something commonly run by end-users as a sanity check. We test using both the default smaller test size as well as larger test sets on our benchmarks. This allows us to see the difference between lighter and heavier workloads. The write access test, however, is done with a 1 GB big test file.SK hynix Platinum P41 1TB Performance Testing 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. In the first three synthetic tests and the compression test, the size of the test file 1 GB.
This is especially for the controllers that use to increase the performance and life of the cell compression, important. The additional compression test can measure the power of the SSD in response to compressibility of the data. 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 4K-64 corresponds to the test Thrd 4K procedure except that the read and write operations are distributed to 64 threads. 4K test the read and write performance is determined at random 4K blocks. In Seq-test the program measures how long it takes to read a 1 GB file to write respectively. These tests are carried out without using the operating system cache. The synthetic tests determine the sequential and random read and write performance of the SSD. 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.
Additionally, it performs the tests using 1 or 64 threads and it determines the SSD's access time. AS SSD Benchmark reads/writes a 1 GByte file as well as randomly chosen 4K blocks. Test the sequential or random read/write performance without using the cache.
