Many small files, or few large ones? That would make you figure out if you should look at 1M or 128K for example.ĭoes it save data, or retrieve data? That would be write and read respectively If you want to figure out (or estimate really, it's not an exact science) if read/write and seq/random is important for the work, try thinking about what the program does. I think video editing especially so, is a mix of random and sequential read/write. These video clips may be saved in a different sort of format in the video editing program, to speed up the editing process, etc.ĮDIT: I've been thinking a bit more on this. Reason I say this, is because when - for example - working on a video, it needs to load videos from some place else on the disk, in varying sizes and bitrates. Mostly these would be sequentially read applications. These are both pretty intensive applications, for both reading and writing. The '1M' and '128K' stand for 1MB and 128KB respectively, showing the sort of size files these tests use (although I don't know for sure if those are actually the sizes, I always just figured that was the case. The reason I say this, is because 'real life' work is often just not laid out in a sequential way, requiring the controller to find data/space all over the drive.ĬrystalDiskMark also has small and large file tests, because a controller may perform differently with many small requests, compared to fewer large requests. HDD's for example have 'okay' sequential performance, but really poor random performance, which generally makes them crappy as an OS/program drive. The memory on the drive may be fast in sequential reads/writes, but if the controller can't keep up with the random requests, it may still prove slow in day-to-day use. Random read/write is when data may be found on different parts of the disk, so the controller needs to be able to find these different parts to read/write efficiently and fast. Sequential is generally the simpler of the two, it's reading or writing data in a sequential pattern, one after the other. Writing: when you are creating/editing a file and making new data to be saved. Read: reading a file, which would include opening a file, opening a program, starting your OS, etc. The bottom four numbers represent random speeds, both in read and write. The application doesn't require any extra knowledge and any user will be able to take advantage of its features and check their HDD's capabilities.The top four numbers represent sequential speeds, both in read and write. To sum it upĪll things considered, CrystalDiskMark puts up a decent performance and it serves its purpose very well. You can manually select the number of test runs, the size of the test and the drive that will be analyzed and then press the corresponding button to start all the tests. This tool doesn't put your processor and RAM under a tremendous stress, but it's better to have no documents open while CrystalDiskMark performs a test, be it a sequential read or write or random 4KB/512KB reads or writes. In order to get the most accurate results it's recommended to close all the other apps before hitting the start button. Speaking about the test, CrystalDiskMark needs just a couple of minutes to perform all the benchmarks. The whole look is designed to make the app very user friendly, so all the information you'll get after conducting the tests will be displayed in the main window. This application was developed to help you get to know your HDD, so it has the power to measure sequential and random read/write speeds while displaying all details to the user with the help of a simple interface. However, pay attention every step of the way, because you might end up with a different homepage and other applications installed as well. Except for destination directory, there isn't anything else to configure. The application runs through the setup process pretty fast. For hard disk drives, one of the possible choices is CrystalDiskMark.

Assessing the performance of various hardware components is a job for specialized software utilities that can thoroughly test several parameters before reaching a qualified conclusion.
