DiskMark - speed test for Mac OS X (macOS) Benchmark the performance of your flash (pen/usb), solid state, hard disk drives in just 60 seconds.DiskMark performs real world speed tests and shows:. Sequential read/write speeds which is the performance you see when copying large files. Random read/write speeds which is the performance you experience when opening or using programs that read and write a lot of files to disk. DiskMark is extremely simple to use and invaluable if you work with any USB drives (flash or external harddisks). And, a history of benchmarks lets you quickly compare your own drives. Why should I benchmark the performance of my disks? Most newer MacBooks and iMacs come with solid state hard drives which are incredibly fast atleast when running normally.
Using DiskMark you can see if the performance deteriorates due to age or due to bloatware on your system. Your external hard disks and flash drives might have multiple factors affecting their performance which should be monitored closely. The single most important thing you should do is ensure you are using USB 3.0 or USB 3.1 devices. Newer technologies such as UASP are coming out often that squeeze out every last ounce of performance out of your external storage devices.
Welcome to Speed Tests Web site for USB Flash Drives. In this page, you can find the speed test results of USB flash drives, made by USBDeview utility. USBDeview make this test by writing a large file into the USB flash drive, and then reading back the same file to getting the read speed. Aug 07, 2014 How fast are your flash drives and external hard drives? How to test the speed of your USB drives. It’s a full drive diagnostic utility that can test the health of your drive and scan for.
What are sequential speeds? These speeds are what you would expect when copying/moving large files. This is the best performance you should expect from your disk. Typical speeds (MegaBytes per Second):. SSD: 400-800 MB/s. HDD/USB3.0: 50-200 MB/s.
USB2.0/Flash: 10-40 MB/s Sequential write speeds on flash devices are usually much slower. What are random access speeds? These speeds are what you would expect when working with complex programs that deal with a lot of files.
Diskmark uses thousands of 8 KB files to test this performance - this is the lowest performance you should expect from your disk. Typical read speeds (MegaBytes per Second):. SSD: 20-100 MB/s. HDD/USB3.0: 5-20 MB/s. USB2.0/Flash: 1-5 MB/s Random write speeds are usually half of random read speeds.
Welcome to Speed Tests Web site for USB Flash Drives. In this page, you can find the speed test results of USB flash drives, made.
USBDeview make this test by writing a large file into the USB flash drive, and then reading back the same file to getting the read speed. The speed is calculated and displayed in Megabytes per second (MB/Sec). Be aware that all these tests are made by making a sequential read and write operations of a single file. When you use multiple small files, you'll probably get much lower read/write performances. If you want to test the read/write speed of your own USB drives and share the results with other people, you can follow the instructions in this page:.

There is also a, which contains a summary of speed tests for USB drives that accumulated 5 speed tests or more. Search other USB flash drives. Some Remarks. You can click the column headers of the speed tests table in order to sort by the desired field.
For example, if you want to easily find out the drives with largest write speed, simply click the 'Write Speed' link in the column header. The vendor name in the speed tests table is determined according to the VID (Vendor ID) of the USB device. The vendor names list was taken from the latest VID/PID list in.
The drive size displayed in the speed tests table is the real size of the flash drive, and it represents the largest file size that you can copy into this drive. Be aware that for most vendors, the actual size of files that you can store inside the drive is less than the offical drive size. For example, if you purchase a 4GB USB flash drive, the real drive size might be 3.7 GB. If you can click the product name link, you'll get the list of all speed tests of products with the same PID and VID. In order to keed this speed tests table reliable, I reserve the right to remove speed test entries that looks extremely unreliable. Because the database is already quite large, the main page only lists the USB speed tests submitted in the last 60 days.
To more easily compare the speed of USB flash drives, you can filter the list according to drive size group: Notice that the USB devices of last size group (above 64 GB) are not really flash drives. They are external hard disk drives plugged to USB.
I originally created this Web site for flash drives, but because some people already submitted the speed test results of external USB disks, I added a group for them too.
