DiskSpd and Disk Drill are both associated with storage and disk management, but they are designed for very different purposes. DiskSpd is a Microsoft-developed command-line storage performance testing utility, while Disk Drill is a data recovery and disk-management application designed for recovering lost files and analyzing storage devices.
Because their primary functions differ, comparing DiskSpd vs Disk Drill is less about choosing between equivalent products and more about understanding which type of storage task each tool is designed to handle.

What Is DiskSpd?
DiskSpd is an open-source storage performance testing tool developed by Microsoft. It is designed to measure storage subsystem performance using configurable workloads.
Rather than providing a graphical interface for everyday disk management, DiskSpd allows users to generate controlled I/O workloads and collect detailed performance measurements.
It can be used to evaluate:
- Sequential read performance
- Sequential write performance
- Random read performance
- Random write performance
- I/O operations per second
- Throughput
- Latency
- Queue behavior
- Storage response characteristics
DiskSpd is particularly useful in environments where storage performance needs to be measured under repeatable conditions.
Key DiskSpd Features
- Command-line operation
- Configurable I/O workloads
- Sequential and random access testing
- Read and write testing
- Adjustable block sizes
- Configurable queue depth
- Multiple outstanding I/O operations
- CPU and storage performance measurements
- Detailed benchmark output
- Automation through scripts
- Open-source availability
DiskSpd is therefore primarily a benchmarking and storage-performance analysis tool, not a general-purpose disk utility.
What Is Disk Drill?
Disk Drill is a data recovery and disk-management application developed by CleverFiles. It provides a graphical interface for scanning storage devices and attempting to recover lost or deleted data.
The software is intended for scenarios involving:
- Accidentally deleted files
- Formatted drives
- Lost partitions

- USB drives
- Memory cards
- Internal hard drives and SSDs
Disk Drill also provides additional disk-related utilities beyond file recovery, depending on the operating system and product version.
Key Disk Drill Features
- Deleted-file recovery
- Partition recovery
- Deep scanning
- Quick scanning
- Recovery from multiple storage devices
- Support for common file systems
- Graphical recovery interface
- Disk monitoring features
- Disk-management utilities
- Previewing recoverable files
Unlike DiskSpd, Disk Drill is designed for interactive use by people who may not be comfortable working from a command-line environment.
Core Functionality Comparison
The most important distinction between DiskSpd and Disk Drill is their intended workload.
DiskSpd: Measuring Storage Performance
DiskSpd generates I/O workloads against a storage device and measures how the storage subsystem responds.
A storage administrator might use it to compare:
- Two SSDs
- Different RAID configurations
- Local versus network storage
- Different queue depths
- Different block sizes
- Storage configurations before and after optimization
Because workloads can be configured in detail, DiskSpd is useful for controlled benchmarking.
Disk Drill: Recovering Lost Data
Disk Drill approaches storage from a data-recovery perspective.
A user might run it after:
- Accidentally deleting important files
- Formatting a USB drive
- Losing access to a partition
- Experiencing a storage-device problem
- Removing files from a memory card
The application scans the storage medium for recoverable information and presents potential results through its graphical interface.
These functions are fundamentally different: DiskSpd measures storage behavior, while Disk Drill attempts to recover data from storage.
Performance
DiskSpd Performance
Performance measurement is DiskSpd’s core purpose.
The tool can generate repeatable workloads with parameters such as:
- Block size
- Read/write ratio
- Random/sequential access
- Queue depth
- Number of threads
- Duration
- Target file or device
This allows storage performance to be analyzed under specific conditions rather than relying solely on a single generic benchmark score.
The results can be used to examine metrics such as throughput, IOPS, and latency.
However, benchmark results depend heavily on workload configuration. A disk can perform very differently under sequential reads compared with random writes, so DiskSpd results need to be interpreted in the context of the test parameters.
Disk Drill Performance
Disk Drill is not primarily a storage benchmark.
Its performance is generally more relevant to how quickly it can scan storage and identify potentially recoverable files. Scan duration can depend on:
- Storage capacity
- Drive health
- Connection interface
- File-system condition
- Scan method
- Amount of recoverable data
- Computer hardware
A large or damaged storage device may require substantial time to scan.
Therefore, Disk Drill should not be evaluated using the same performance criteria as DiskSpd.
Compatibility
DiskSpd Compatibility
DiskSpd is closely associated with Windows storage testing and is particularly suitable for Windows-based infrastructure and performance analysis.
Because it is command-line based, it can also be incorporated into:
- Batch scripts
- PowerShell workflows
- Automated testing
- Server testing
- Storage validation procedures
Microsoft’s DiskSpd project provides releases and documentation through its official GitHub repository.
Disk Drill Compatibility
Disk Drill is primarily a desktop application and supports Windows and macOS.
It can work with various storage media, including:
- Internal HDDs
- SSDs
- External drives
- USB flash drives
- Memory cards
- Other supported storage devices
Its graphical interface makes it more accessible for users who want to scan and recover data without learning command-line parameters.
System Requirements
| Requirement | DiskSpd | Disk Drill |
| Windows | Yes | Yes |
| macOS | Not its primary platform | Yes |
| Graphical interface | No | Yes |
| Command line | Yes | Limited |
| Internet connection | Usually unnecessary for testing | May be needed for installation/licensing and updates |
| Large storage device support | Yes | Yes |
| Specialized hardware | Not required | Not required |
| Technical knowledge | Moderate to advanced | Basic to moderate |
| Automation | Strong | Limited compared with command-line tools |
DiskSpd is lightweight and can run from the command line, but understanding its workload parameters requires some technical knowledge.
Disk Drill generally has lower entry barriers because its main workflows are presented through a graphical interface.
Use Cases
Where DiskSpd Fits
DiskSpd is useful for storage professionals, system administrators, developers, and hardware testers.
Typical use cases include:
- SSD benchmarking
- HDD benchmarking
- Storage-array testing
- Server storage evaluation
- IOPS measurement
- Latency analysis
- Storage configuration testing

- Infrastructure validation
- Automated storage benchmarks
For example, an administrator could use DiskSpd to compare storage performance before and after changing RAID or caching configurations.
Where Disk Drill Fits
Disk Drill is designed for users and technicians who need to recover data.
Typical use cases include:
- Recovering accidentally deleted documents
- Recovering photographs
- Recovering files from formatted drives
- Searching for lost partitions
- Recovering files from removable media
- Scanning damaged storage devices
- Previewing potentially recoverable files
Its graphical workflow is particularly relevant when the main objective is finding and recovering files rather than measuring disk performance.
Pros and Limitations of DiskSpd
Pros
- Designed specifically for storage performance testing
- Highly configurable workloads
- Supports sequential and random I/O
- Useful for measuring IOPS, throughput, and latency
- Command-line operation
- Suitable for automation
- Useful in server and enterprise testing
- Open-source
- Developed by Microsoft
Limitations
- Not designed for data recovery
- Command-line interface can be intimidating for beginners
- Benchmark parameters require technical understanding
- Results can be misleading if workloads are poorly configured
- Primarily focused on performance measurement rather than everyday disk management
DiskSpd is therefore specialized toward storage benchmarking and performance analysis.
Pros and Limitations of Disk Drill
Pros
- Graphical user interface
- Designed for data recovery
- Supports multiple storage-device types
- Provides scanning and recovery workflows
- Can identify deleted and lost files
- Provides file previews in supported situations
- More approachable for nontechnical users
- Available for Windows and macOS
Limitations
- Not a dedicated storage-performance benchmark
- Recovery success depends on the condition of the storage device
- Severely overwritten data may not be recoverable
- Scanning large drives can take significant time
- Some functionality may depend on the product version or licensing model
- Recovery operations should be performed carefully to avoid further data loss
Data recovery is never guaranteed. If a drive is physically failing or contains important irreplaceable information, repeated scanning or writing to the affected device can create additional risks.
User Experience
DiskSpd and Disk Drill provide very different user experiences.
DiskSpd Interface
DiskSpd uses command-line parameters. Users need to understand the syntax and configure the workload they want to test.
This approach is beneficial for automation and repeatable testing but can be less accessible to beginners.
Disk Drill Interface
Disk Drill uses a graphical interface where storage devices and recovery options are presented visually.
This makes common recovery workflows easier to navigate without requiring users to memorize command-line parameters.
The difference can be summarized as:
DiskSpd → configuration and measurement
Disk Drill → scanning and recovery
DiskSpd vs Disk Drill for SSD Testing
If the objective is to measure SSD performance, DiskSpd is the more directly relevant category of software because it is specifically designed to generate and measure storage I/O workloads.
It can be configured for different block sizes, access patterns, queue depths, and read/write workloads.
Disk Drill does not serve the same benchmarking role. Its storage-related functionality is primarily oriented toward recovery and disk management.
DiskSpd vs Disk Drill for Data Recovery
For data-recovery tasks, the situation is reversed.
Disk Drill is specifically designed to scan storage devices and locate potentially recoverable files.
DiskSpd does not provide a file-recovery mechanism. Running a DiskSpd workload against a drive is also not an appropriate method for recovering lost data.
Therefore, the tools should not be treated as interchangeable for recovery scenarios.
Can DiskSpd and Disk Drill Be Used Together?
In certain workflows, the two tools can exist on the same computer while serving completely separate purposes.
For example, a technician might use Disk Drill to investigate a storage problem and recover files, while DiskSpd could later be used in a controlled environment to evaluate the performance of a replacement or repaired storage configuration.
They should, however, not be treated as complementary tools for the same immediate operation. DiskSpd performs I/O testing, while Disk Drill focuses on data recovery.
Key Differences at a Glance
- DiskSpd is a storage-performance benchmarking tool; Disk Drill is primarily a data-recovery application.
- DiskSpd uses a command-line interface; Disk Drill primarily uses a graphical interface.
- DiskSpd focuses on IOPS, throughput, latency, and configurable I/O workloads.
- Disk Drill focuses on deleted files, lost partitions, and recoverable data.
- DiskSpd is better suited to technical benchmarking and automated testing.
- Disk Drill is designed for interactive recovery workflows.
- DiskSpd does not replace recovery software, and Disk Drill does not replace a dedicated storage benchmark.
- Their hardware and software requirements differ because their workloads are fundamentally different.
Final Comparison
DiskSpd and Disk Drill address separate areas of storage management. DiskSpd is centered on storage performance testing, giving technical users control over I/O workloads and providing measurements that can help evaluate storage configurations.
Disk Drill is centered on data recovery, offering a graphical workflow for scanning storage devices and attempting to recover deleted or lost files.
The appropriate tool therefore depends on the task being performed. Storage benchmarking, IOPS testing, latency analysis, and repeatable performance experiments fall within DiskSpd’s primary purpose, while deleted-file recovery, lost-partition scanning, and recovery-oriented storage analysis fall within Disk Drill’s scope. Neither tool is a direct replacement for the other, and their differences in interface, requirements, and functionality reflect their distinct roles in storage-related workflows.
