CrystalDiskMark Download – Quick Overview

What Is CrystalDiskMark?

CrystalDiskMark is a Windows storage benchmark application designed to measure how quickly a drive can read and write data.

Unlike drive-health utilities that focus on temperature and S.M.A.R.T. information, CrystalDiskMark focuses specifically on storage performance.

The program can benchmark internal NVMe SSDs, SATA SSDs, traditional hard drives, and many external or removable storage devices.

CrystalDiskMark for Windows 11 & 10

CrystalDiskMark works on Windows 11 and Windows 10 as well as several older supported Windows versions.

For most users, the Standard Edition is the simplest choice. Crystal Dew World also provides Shizuku and Aoi editions that primarily offer different visual themes.

Installer Edition

The Installer edition provides the normal Windows installation experience. It is convenient if you expect to use CrystalDiskMark regularly.

ZIP Edition

The ZIP version does not require traditional installation. Extract the archive into a folder and run CrystalDiskMark directly.

This can be useful for occasional benchmarking, troubleshooting multiple PCs, or keeping disk utilities together in a portable tools folder.

CrystalDiskMark Main Interface & Benchmark Settings

CrystalDiskMark uses a compact interface focused on storage benchmarking. Before running a test, check the number of runs, test size, selected drive, profile, and measurement unit.

Number of Test Runs

This setting determines how many times CrystalDiskMark performs each benchmark. More runs can provide more consistent results but also increase testing time and storage write activity.

Test Size

Larger test files can provide a more demanding benchmark. Smaller test sizes may be more convenient for slower devices such as some USB flash drives.

Test Drive

Use the drive selector to choose the SSD, HDD, USB drive, or other Windows volume you want to benchmark.

Benchmark Buttons

Selecting All runs the available benchmark tests. Individual benchmark rows can also be run separately when you need only a specific measurement.

Peak, Real World & Demo Profiles

CrystalDiskMark provides multiple measurement profiles. Peak Performance focuses on higher-performance capabilities, while Real World Performance is intended for more practical workload conditions.

Mix-capable profiles can also evaluate combinations of read and write activity.

CrystalDiskMark Sequential vs Random 4K Tests Explained

Sequential Read and Write Speed

Sequential performance measures how quickly a storage device can process relatively large blocks of data arranged sequentially.

This type of performance is especially relevant when copying large files, moving videos, working with large archives, loading large project files, or transferring data between fast storage devices.

Modern NVMe SSDs can achieve much higher sequential throughput than SATA SSDs or traditional hard drives, but sequential speed is only one part of overall storage performance.

Random 4K Performance

Random tests measure performance when accessing smaller pieces of data located throughout the storage device.

This is more representative of many everyday operating-system workloads, including application responsiveness, Windows startup activity, loading many small files, software installation, multitasking, and general desktop use.

MB/s, GB/s, IOPS & Latency

MB/s

Megabytes per second measures how much data the drive can transfer each second.

GB/s

Gigabytes per second can make the results of very fast NVMe SSDs easier to read.

IOPS

IOPS means Input/Output Operations Per Second and is particularly useful for evaluating random workloads.

Average Latency

Latency indicates how long storage operations take to complete. Lower latency is generally better.

Looking at throughput, IOPS, and latency together gives a more complete picture than judging a drive by only one benchmark number.

CrystalDiskMark NVMe, SATA SSD, HDD & USB Benchmarking

NVMe SSD Benchmarking

CrystalDiskMark is particularly useful for benchmarking high-performance NVMe SSDs and includes an NVMe SSD settings option.

Before comparing your result with a manufacturer’s specification or another PC, remember that NVMe performance can depend on several factors:

• PCIe generation.
• Number of PCIe lanes.
• SSD capacity.
• Controller and NAND configuration.
• Available free space.
• SSD temperature and thermal throttling.
• CPU performance.
• Background applications.
• Power settings.
• Driver configuration.
• Benchmark test size and settings.

For example, a PCIe 4.0 SSD installed in a system limited to PCIe 3.0 may not reach its advertised maximum sequential performance.

Testing SATA SSDs and HDDs

CrystalDiskMark can also benchmark SATA SSDs and traditional hard drives.

A SATA SSD typically has lower maximum sequential throughput than a modern NVMe SSD because of the SATA interface, but it can still provide much stronger random performance and responsiveness than a mechanical hard drive.

HDD benchmark results can vary depending on drive RPM, cache, data location, fragmentation, and background activity.

Testing USB Drives and External Storage

CrystalDiskMark can test many USB flash drives, portable SSDs, external HDDs, external SSD enclosures, and memory-card storage that appears as an accessible Windows drive.

External storage performance depends on both the storage device and its connection. A fast SSD connected through a slower USB interface can be limited by that interface.

How to Read CrystalDiskMark Results

A common mistake is looking only at the largest number in the benchmark.

Instead, consider the workload that matters to you. High sequential speed is useful for large-file transfers, while strong random performance is more relevant to many small-file and operating-system workloads.

For meaningful comparisons, use the same CrystalDiskMark major version and equivalent test settings.

Why CrystalDiskMark Results May Be Lower Than Advertised

A lower benchmark result does not automatically mean that your SSD is defective.

Interface Limitation

The motherboard, laptop, PCIe generation, lane configuration, SATA interface, USB interface, or enclosure can limit storage performance.

Thermal Throttling

High-performance NVMe SSDs can become hot during sustained workloads and may reduce performance when temperatures rise.

Background Disk Activity

Windows Update, antivirus scanning, indexing, downloads, cloud synchronization, or other applications can use the drive while CrystalDiskMark is running.

If Microsoft OneDrive is actively synchronizing large amounts of data, benchmark results can also be affected. See our Microsoft OneDrive Download for Windows guide for more information about OneDrive on Windows.

Power Settings

Laptop power-saving modes and other system power settings can sometimes affect performance.

Different Benchmark Configuration

Drive manufacturers may use different software, queue depths, test sizes, hardware, and test conditions when publishing performance specifications.

Drive Capacity and Free Space

Different capacities of the same SSD model can perform differently, and available free space or cache behavior can also influence results.

CrystalDiskMark vs Windows Task Manager vs CrystalDiskInfo

CrystalDiskMark vs Windows Task Manager

Task Manager is useful when you want to see which applications are currently using your disk. CrystalDiskMark is better when you want a controlled benchmark of storage performance.

CrystalDiskMark vs CrystalDiskInfo

Despite their similar names, CrystalDiskMark and CrystalDiskInfo perform different jobs.

If you want to benchmark storage speed, use CrystalDiskMark. If you want to inspect drive health, CrystalDiskInfo is the more appropriate Crystal Dew World utility.

Is CrystalDiskMark Safe for SSDs?

CrystalDiskMark is a legitimate benchmarking utility from Crystal Dew World, but storage benchmarking generates real read and write activity.

Crystal Dew World warns that repeatedly running CrystalDiskMark can contribute additional writes to SSDs and USB memory.

Useful reasons to benchmark include installing a new drive, changing hardware configuration, comparing storage devices, or investigating an unexpected performance problem.

CrystalDiskMark Troubleshooting

Benchmark Shows Unexpectedly Low Speed

Close storage-intensive applications and allow background activity to settle. Confirm that the correct drive and benchmark settings are selected.

For NVMe SSDs, also check the motherboard slot, PCIe generation, and lane configuration.

Results Change Between Tests

Some variation is normal. Drive temperature, cache behavior, background processes, test size, and general system activity can affect benchmark results.

Use consistent settings when comparing results.

CrystalDiskMark Shows 0 or Does Not Complete a Test

Restart CrystalDiskMark and check that the selected drive is accessible. Close applications heavily using the disk and try again.

If necessary, restart Windows before repeating the benchmark.

External Drive Is Slow

Check the USB port, cable, enclosure, and interface speed. A fast external SSD connected through an older or slower USB interface can be limited by that connection.

Network Drive Does Not Appear

Crystal Dew World’s documentation notes that network drives may not appear when CrystalDiskMark is launched with administrator rights.

If you need to benchmark a network drive, try running CrystalDiskMark without administrator privileges.

How to Update CrystalDiskMark

If you use the Installer edition, download the newer official installer and run it.

For the ZIP edition, extract the newer files and replace the older standalone copy as appropriate.

When comparing old and new benchmark results, remember that different major CrystalDiskMark versions may not produce directly comparable results.

How to Uninstall CrystalDiskMark

Installer Edition

1. Open Windows Settings.
2. Go to Apps.
3. Open Installed apps or Apps & features.
4. Find CrystalDiskMark.
5. Select Uninstall.
6. Complete the removal process.

ZIP Edition

No traditional Windows uninstall process is necessary. Close CrystalDiskMark and delete the extracted files when you no longer need them.
