Crystal Disk Mark Zip
Jahed Stetter
CrystalDiskMark is an open source disk drive benchmark tool for Microsoft Windows from Crystal Dew World. Based on Microsoft's MIT-licensed Diskspd tool,[2] this graphical benchmark is commonly used for testing the performance of solid-state storage.[3][4] It works by reading and writing through the filesystem in a volume-dependent way. It generates read/write speeds in sequential and random positions with varying numbers of queues and threads.[5] Solid-state drives tend to excel at random IO, as unlike hard drives, they do not need to seek for the specific position to read from or write to.[6]
CrystalDiskInfo is an MIT-licensed S.M.A.R.T. utility for reading and monitoring disk drive status. Like CrystalDiskMark, this tool is designed with an emphasis around solid state devices, supporting NVMe connections in addition to the usual PATA and SATA. Other features include Intel RAID support, e-mail and sound warnings, and AAM/APM adjustment.[9]

Systems Engineer illustrator), and voiced by Sumire Uesaka of KING RECORD CO., LTD.,[30][31] was the second mascot used in Crystal Dew World's software, introduced in CrystalDiskInfo 7.1.0 (2017-08-04).[32][33]
Virtual salesperson android Tsukumo Tokka (Japanese: バーチャル販売員アンドロイドの九十九ツクモトッカ), a Virtual Cast Shopping (Japanese: バーチャルキャストショッピング) (Project White Co., Ltd.'s online channel) mascot designed by ?,[38] was the third mascot used in Crystal Dew World's software, introduced in CrystalDiskMark 8.0.2 (2020-06-01).[17][39]
Awhile back, I made a video about USBc and the classic Mac Pro but lamented yet ago the terrible benchmarking on macOS. The first commenter on FaceBook pointed out that we finally have a good disk benchmark utility AmorphousDiskMark. While it isn't a direct port, it's heavily inspired by the famed and loved Windows utility, CrystalDiskMark.
BlackMagic's Disk Speed Test only tests one thing, continuous throughput. This is useful but only measures one aspect of an SSD, and doesn't necessarily mimic accurately how most disk interactions occur. Random Read and Write tests are as important, if not more so, as many SSDs can deliver fast maximum continuous read and writes but much less so for random small data blocks. CrystalDiskMark tests random reads and writes both as queued requests and single requests. The default depth is pretty high for the test. Usually, an OS wouldn't have that deep of a queue, but the Q1T1 does mimic a singular request. Also, CrystalDiskMark measures IOPS (Input/Output Operations-per-second), which is similar but also a different measure of disk speed.
There's plenty of aspects that aren't covered, such as latency, burst performance, power consumed, and mixed random read/writes, but this is a massive step in the right direction for gauging SSD performance on macOS. Oh yeah, and it's free.
I want to use the Windows app "CrystalDiskMark" for testing drives. Before you suggests the alternatives - GNOME Disks, bonnie++ or hdparm - I already know about these. The thing is the output of CrystalDiskMark has kind of become a de facto standard (because Linux desktop share is < 3% and Windows > 61%). I am successfully running CrystalDiskMark under Wine but the difficulty is its menu shows Windows drive letters e.g, C:, D:, E: ... How does Zorin map partitions into Windows drive letters? Confusingly, it shoes more drives than I have mounted. Is it also mapping the tmpfs partitions?
However, CrystalDiskMark does show drive letters and at least some of these drive letters match Linux partitions by size. I was able to run CrystalDiskMark on a particular flash drive because it had a unique partition size. Unfortunately, all the other partitions have the same size and cannot be differentiated by size. It seems to me Wine is mapping Linux partitions into Windows drive letters. The flash drive was formatted as MBR/FAT32. I really only want to use CrystalDiskMark for testing flash drives which I can always format at least temporarily to MBR/FAT32. The other partitions were on my hard disk which was GPT/EXT4 so CrystalDiskMark did see these GPT partitions. I can always create a small NTFS or FAT32 partition on the GPT hard disk if I wanted to test the hard disk.
Wine is a Windows emulator and therefore it is only logical that it will emulate Windows drive letters by mapping into Linux partitions. I have found the mapping - open the menu item - Wine -> Configure Wine -> Drives.
I also created a GPT/EXT4 partition and CrystalDiskMark worked on this partition also. Incidentally, if I was writing a drive test program I would not use the existing file system but I would create a small temporary "standard" file system and test against that. That would remove the performance of the file system as a variable. The idea is to test the performance of the drive independent of the file system.
The problem with using Linux software for drive testing is most of the world will not understand what those numbers mean. But CrystalDiskMark is so popular that it has become a de facto standard for testing drives.
In Zorin OS, and generally in Linux systems, drive letters are not used to map partitions like in Windows. Instead, Linux uses a hierarchical file system where each partition is mounted to a specific directory within the file system.
When running CrystalDiskMark under Wine, the drive letters you see in the application's menu are virtual representations provided by Wine to emulate the Windows environment. These drive letters do not necessarily correspond to the actual drive letters used in your Zorin OS system.
Regarding the extra drives shown in CrystalDiskMark that you haven't mounted, it's possible that Wine is presenting some virtual or virtualized drives that may include temporary or system-related partitions. These may include things like the WINEPREFIX directory or other internal Wine-related elements.
It's important to note that these virtual drives shown in CrystalDiskMark do not necessarily represent the actual mounted partitions in your Zorin OS system. To accurately identify and test your mounted partitions, you should refer to the Linux utilities you mentioned earlier & further suggested in above posts, such as GNOME Disks or command-line tools like bonnie++ or hdparm, as they provide information specific to your Linux system's partitions and devices.
To help further:
Linux, drives and partitions are typically represented as block devices and are accessed through the directory structure. The root of the file system is denoted by a single forward slash (/). Here are some common directories used in Linux for drive identification:
" /dev ":
This directory contains device files that represent hardware devices, including drives and partitions. For example, "/dev/sda" represents the first hard drive, and "/dev/sda1" represents the first partition on that drive.
" /mnt " or " /media ":
These directories are used as mount points for manually mounting external or internal drives. Mounting a drive attaches it to a specific directory in the file system, allowing you to access its contents.
It's important to note that in modern Linux distributions, drives are often automatically mounted under the "/media" directory when connected. Each mounted drive is usually assigned a subdirectory under "/media", which can be named based on the drive's label or other identifiers.
Additionally, Linux allows for more flexible and customizable mounting options, including network shares and virtual file systems. This allows you to mount various types of drives and file systems seamlessly within the directory structure.
Overall, Linux does not rely on drive letters like Windows but instead uses a directory-based approach, providing greater flexibility and control over drive identification and mounting.
Hope this helps.
The work is being done by 3 Windows system calls - CreateDirectory(), CreateFile() and WriteFile() these can very efficiently be emulated by the Linux system calls mkdir(), open() and write(). CrystalDiskMark is file system agnostic - the kernel knows the file system type from the path and will redirect the system call to the appropriate file system driver ext2, ext3, ext4, ntfs, fat32. It should work under Wine.
However, since CrystalDiskMark is using the existing file system the benchmark will have a dependency on the implementation of that file system so to be comparable to a test run on Windows CrystalDiskMark should be run on FAT32 or NTFS whichever was used on Windows.
However. if you open the menu item Wine -> Configure Wine -> Drives you will see some drive letters are for actual physical partitions. CrystalDiskMark will run on these partitions and since it is file system agnostic it doesn't matter if they are ext2, ext3, ext4, ... I have test this and it works.
By who? I'm a technician and engineer, yet I've never heard of this software. I can use disk management as well as dd, gparted or disks to get the info I need. You seem to be a power user, but refuse the tried and true tools of the industry. Confusing.
