Follow these directions to test your drive's read/write speeds. If testing an external drive, connect that drive to your computer; Launch Blackmagic Disk Speed Test; In this window, click on the Gear Icon; In the drop down menu, choose Select Target Drive. In this window, navigate to a folder on your external drive and select it. Then click Open.

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.
- Sequential 128 KiB block read/write tests with Queue Depth=1, 2, 4, 8, 16, 32, 64, 128, 256, 512, or 1024
- Random sequence 4 KiB block read/write tests with Queue Depth=1, 2, 4, 8, 16, 32, 64, 128, 256, 512, or 1024
- Sequential 1 MiB block read/write tests
- Random sequence 4 KiB block read/write tests
- Read/write MB/s scores
- Read/write IOPS scores in tooltip
- Test data: random or zero
- Test size: 50 MiB, 100 MiB, 500 MiB, 1 GiB, 2 GiB, 4 GiB, 8 GiB, 16 GiB, or 32 GiB
- Test interval: 0 seconds, …, 10 minutes
↓ 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

Blackmagic Disk Speed Test Windows 10 Download
Get the read and write speed from your harddisks, cdrom devices and network servers in Kilobyte, Megabyte or even Gigabyte per Second. Single click speed test using the filesystem. This test shows you the sequential read & write access speed and the random access speed using 4KB blocks and 32 concurrent threads. You can select multiple drives, these will be tested one after the other and the results will be written to a log file. So you can easily compare multiple drives.
↓ 08 – Performancetest’s Advanced Disk Test Trial 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:
- 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

Just a quick note on possibilities available to do some bench-marking of NAS performance. Quite often Blackmagic Disk Speed Test or Intel NAS Performance Toolkit are being used for this. But there are some problems with those: first one is nice and cool but for Mac only, second is good but no longer supported by Intel as it reached its EoL.
So if you look for the other options you may use the following:
ToTu Soft LAN Speed Test – they have commercial and free versions, and promise to deliver Mac OS release soon.
NAS performance tester by Ulrik D. Hansen, absolutely free and with source code available (though it only measures read/write speed values).
I really liked this last option as it is portable and allowed me to do some quick tests against iSCSI target hosted on my Synology DS415+ (gigabit Ethernet connection; 1 drive only, no RAID, both data and header digests enabled). You may see test results below.
Using 400 Mb file:
The same test run a bit later with both header and data digests disabled:
Using 8000 Mb file:
And here is the same test with digests disabled:
Blackmagic Disk Speed Test Windows
Of course this is quick and dirty measurement, but at least now I have some baseline and tool to measure how changes in my infrastructure or its configuration influence performance. For example I saw interesting reports that NFS share on Synology outperform iSCSI target (at least in terms of IOps), and in other source there were graphs showing negligible performance cost of iSCSI digests (alongside these graphs that material emphasized importance of data integrity you gain with digests), but it will be nice to verify all these claims.
UPDATE (20.03.2015): I did the same tests with disabled digests (see additional screenshots above), so performance cost is not entirely negligible, especially for read and for large chunks of date.
