Alternatives to CrystalDiskMark
The standard Windows disk benchmark, measuring sequential and random read and write speeds in a few clicks. The listings below can replace it for an important use case. Each note says what changes if you switch.
The original
CrystalDiskMark
The standard Windows disk benchmark, measuring sequential and random read and write speeds in a few clicks.
Replacements
Listings that take over the same core job as CrystalDiskMark.
AS SSD Benchmark
Quick Windows benchmark tool for testing SSD read and write speeds.
AS SSD Benchmark is a closed-source free Windows tool focused specifically on SSD speed tests, with a narrower feature set and no installation needed.
GNOME Disks
A graphical disk utility for GNOME that partitions, formats, benchmarks and images drives on Linux.
GNOME Disks moves the task to Linux, offering a built-in read and access-time benchmark as one part of a general graphical disk utility.
KDiskMark
A graphical disk benchmark for Linux that runs fio tests and shows easy-to-read results.
KDiskMark offers CrystalDiskMark-style speed tests on Linux with configurable block size, queues and threads, running fio underneath, so fio must be installed and Windows is not supported.
ATTO Disk Benchmark
A free benchmark from ATTO Technology for measuring storage read and write performance.
ATTO Disk Benchmark is a free, proprietary Windows tool from a storage hardware maker that measures read and write performance, with little documentation on the vendor's pages.
fio
A flexible command-line I/O tester for benchmarking and stress-testing storage devices.
fio is a free, open-source Linux command-line I/O tester with job files, many I/O engines and detailed latency and IOPS output, but a steep learning curve and no GUI.
Also worth comparing
These listings name CrystalDiskMark as their own alternative, so the relationship runs both ways.
DiskSpd
Microsoft's command-line storage load generator for benchmarking disk performance on Windows.
CrystalDiskMark is also MIT-licensed and Windows only, but uses a graphical interface with preset sequential and random tests instead of configurable scripted workloads.
Similar software
Related functionality, not a direct replacement.
CrystalDiskInfo
Reads the health data your drives already record and tells you plainly whether one is dying.
smartmontools
Reads the SMART health data built into disks and runs self-tests, giving advance warning before a drive fails.
HDDScan
A free Windows utility for testing hard drives and SSDs, reading SMART data and running surface tests.
GSmartControl
A graphical interface for smartctl that shows the health of hard drives and SSDs.
