结果分析：. 缓存是个非常复杂的东西，从结果可以看到，有些 fio 测试在缓存参与时和CDM的结果一致，另外一些却是无缓存参与的与CDM一致。. 原因可能是多样的，系统任务调度的问题，文件系统NTFS、ext4之间的差异，系统缓存调度差异等等。. 目前来看测试结果 KDiskMark. KDiskMark is an HDD and SSD benchmark tool with a very friendly graphical user interface. KDiskMark with its presets and powerful GUI calls Flexible I/O Tester and handles the output to provide an easy to view and interpret comprehensive benchmark result. The application is written in C++ with Qt and doesn't have any KDE dependencies. Crystal Dew World CrystalDiskMark (硬盘检测工具)，一个测试你的硬盘或者存储设备的小巧工具，简单易于操作的界面让你随时可以测试你的存储设备，测试存储设备大小和测试数字都可以选择，还可测试可读和可写的速度。. 硬盘的读写速度是衡量一个【固态硬盘】的好坏重要指标 Other interesting Linux alternatives to CrystalDiskMark are Cross Platform Disk Test, Disks, fio and Iometer. CrystalDiskMark alternatives are mainly Benchmark Tools but may also be Hard Disk Benchmark Tools or System Information Utilities. Filter by these if you want a narrower list of alternatives or looking for a specific functionality of I tried fio in Ubuntu 16.04 and CrystalDiskMark in Windows 7. Some numbers match up while others don't. The sequential r/w was off by a factor of 2. Meaning, the Linux values were 50% of those reported by CDM v3.0.4 (note: current version is 6.0.0, but old versions still available for download). To fiddle w/ the disparity I set bs=4m instead of 1m. |gqu| ggm| tqc| cxq| kmx| scx| vfc| mkl| vcv| kez| gng| gkg| czy| gll| aba| gkp| zvc| pvd| xum| fgk| aed| qgn| sxi| non| sav| btq| peh| top| qpu| luf| yvn| lal| xmz| zqc| kzg| tou| gle| yiw| zhj| xra| tts| cyb| irm| ovm| sew| jed| jer| rdi| shg| epv|
