The disk can be directly connected to your Mac or be on a network. If a disk has partitions, you can use one of the partitions for your backup disk. Time Machine can’t back up to iPhone, iPad, or iPod or to a disk formatted for Windows. If you connect a disk formatted for Windows, it can be reformatted (permanently removing all data) to a Mac. Disk Speed Test (by Blackmagic) is a hard disk benchmarking application for Mac OS X.It quickly measure and certifies the read/write rate of your hard disk, so that you can access it’s performance and quality.
Disk Speed Test (by Blackmagic) is a hard disk benchmarking application for Mac OS X. It quickly measure and certifies the read/write rate of your hard disk, so that you can access it’s performance and quality. This can be quite useful to determine if your hard drive is slowing down due to some reason or if it requires some sort of tweaking to enhance it’s speed. For example, sometimes a hard drive’s performance can be affected due to strained system resources, like in the case of high CPU and RAM consumption.
Moreover, some SSD’s make their benchmark speeds appear faster than what they may actually be capable of. Blackmagic Disk Speed Test measures the true speed of these SSD’s, so that you are able to determine if they are suitable for high quality uncompressed video capture. Disk Speed Test (application) can hence, help you evaluate both performance and readability of your hard drive.
To start hard disk benchmarking, click the Start button. This will initiate your hard drive speed test by using large blocks of data. Before starting the hard drive read & write benchmark test, you can also specify target drive and the amount of load that you wish to put on your hard drive. This can be configured from Settings option (located between read and write meters).
The main window of Disk Speed Test, shows the video qualities which are supported by your hard drive. For example, it marks a tick for 10 Bit RGB 4:4:4 column (NTSC and PAL) during testing. This essentially means that your hard disk will perform smoothly with this video format.
Please Note: This application puts the hard drive under extreme stress, therefore it is advised that you save your work before initiating the test.
Bloackmagic Disk Speed Test works with the following Mac OS X versions:
- Mac OS X 10.6 Snow Leopard
- Mac OS X 10.7 Lion

Which is the fastest Consumer SSD in the market? The Read and Write data by the manufacturer are not an accurate benchmark because they are not real world read write usage. The only way to benchmark them is to test the effective speed. What is an effective speed? It is a measure of how well an Solid-state drives performs under typical consumer workloads, and the only way to measure this is to gather as many real world data from users, this is why UserBenchmark Website is the best site to know the real speed of SSD, HDD, USB, RAM, CPU and GPU.

↓ 01 – CrystalDiskMark | Windows
CrystalDiskMark is a small HDD benchmark utility for your hard drive that enable you to rapidly measure sequential and random read/write speeds. It measure sequential reads/writes speed,measure random 512KB, 4KB, 4KB (Queue Depth=32) reads/writes speed,select test data (Random, 0Fill, 1Fill).
↓ 02 – ATTO Disk Benchmark | Windows
As the industry’s leading provider of high-performance storage & network connectivity products, ATTO has created a widely-accepted Disk Benchmark freeware software to help measure storage system performance. As one of the top tools utilized in the industry, Disk Benchmark identifies performance in hard drives, solid state drives, RAID arrays as well as the host connection to attached storage. Top drive manufacturers, like Hitachi, build and test every drive using the ATTO Disk Benchmark. Specifications:
- Transfer sizes from 512B to 64MB
- Transfer lengths from 64KB to 32GB
- Support for overlapped I/O
- Supports a variety of queue depths
- I/O comparisons with various test patterns
- Timed mode allows continuous testing
- Non-destructive performance measurement on formatted drives
- Hard drive performance test
↓ 03 – AS SSD Benchmark | Windows
With AS SSD Benchmark you can determine your SSD drive’s performance by conducting several specific tests. Test the sequential or random read/write performance without using the cache. AS SSD Benchmark reads/writes a 1 GByte file as well as randomly chosen 4K blocks. Additionally, it performs the tests using 1 or 64 threads and it determines the SSD’s access time.
Two extra benchmark tests examine the drive’s behaviour when (1) copying a few big files, a lot of small files and a mixture of file sizes by using cached copy functions of your OS as well as (2) reading/writing data depending on the data’s compressibility. Works great on Microsoft Windows 10.
↓ 04 – Blackmagic Disk Speed Test | macOS
Disk Speed Test is an easy to use tool to quickly measure and certify your disk performance for working with high quality video! Simply click the start button and Disk Speed Test will write test your disk using large blocks of data, and then display the result. Disk Speed Test will continue to test writes and reads from your disk so you can evaluate both performance and readability over time.
↓ 05 – AmorphousDiskMark | macOS
AmorphousDiskMark measures storage read/write performance in MB/s and IOPS. AmorphousDiskMark is designed to measure the megabytes per second and the Input/Output operations per second and display the results in its main window. The app features four types of tests, each featuring a different kind of data block.

↓ 06 – jDiskMark | Windows | macOS | Linux
Simple Java utility to help bench mark disk IO. Benchmark is done by creating and reading data files to a user directory that can be configured. When doing a combined read and write operation the disk cache is not cleared automatically so the app must be restarted to avoid the cache from affecting read IO performance. Features
- Disk IO read/write performance
- Java cross platform solution
- Saves previous run information
- Single or multi file option
- Sequential or random option
- Detects drive model info
- Adjustable block size
↓ 07 – Passmark Performancetest’s Advanced Disk Test | Free 30 day | Windows
This Advanced Disk Test, which is part of PerformanceTest, measures the data transfer speed when reading or writing data to one or more disks. The speed that data can be transferred between memory and a hard disk drive is one of a system’s most important performance aspects. There are quite a few factors which have a bearing on this speed and the Advanced Disk Drive Test allows the user to vary most of these factors and compare the results.
The test supports any drive that can be mounted under Windows. Including IDE drives, SCSI, RAID, USB key drives, SATA, networked shared drives and external drives. Users have the ability to test multiple drives at the same time using multiple threads, and specify:
Disk Speed Test Mac Free
- The size of the test file used. Larger files mean that the system cache has less of an effect on the test types, which use caching (see below).
- The size of the data block used for each read or write request. Larger blocks mean less requests and can lead to an improvement in performance.
- The choice of four access methods – C/C++ API, Win32 API cached / uncached and raw disk access.
- Sequential or random access (seeking plus reading and writing)
- Synchronous and Asynchronous access
- The split between reading and writing
↓ 08 – Parkdale | Windows | macOS | Linux | Android
