If you want to save your disk speed results, you can click Save Screenshot and choose a directory to save the screenshot. You need make sure you have read and write permissions for the target drive before you click the START button. If you need test some other drive (another local hard drive, a USB drive or a mobile hard drive), you can click Select target drive to choose the storage drive. SettingsĬlick the gear icon above the START button, and there is a popup menu. On the lower panels, you can see which video formats can be supported by your disk. On the dashboard, you can see the write speed and read speed of your disk. When the test is complete, the results are show up on the interface. If you click the START button again during the test, the test will stop. Disk Speed Test will write a temporary file on the disk, and the file will be automatically deleted when you close the program. Run Disk Speed Test, click the START button, and this tool is starting testing the write speed and read speed of the local hard disk on your computer. Get startedĪfter you download and install Blackmagic Desktop Video, Disk Speed Test is automatically installed. When you want to test the disk speed, you can take the following guide. There are Mac, Windows and Linux versions for deferent operating systems. Disk Speed Test is included in Blackmagic Desktop Video software. How to use Blackmagic Disk Speed Testĭisk Speed Test is designed by Blackmageic Design, which is one of the world's leading innovators and manufacturers of creative video technology. If you have ever wondered whether your storage disk is suitable for recording and playback of a particular video format, you can use Disk Speed Test to find out. This disk speed test tool is a very useful application which can measure the read and write speed of a hard disk and give out the reference after test. How to know the hard drive is fast or slow? How to know the disk is suitable for recording and playback super high definition videos or not? We are introducing a disk speed test tool: Blackmagic Design Disk Speed Test. If you need store and playback 4K videos on a hard drive on your computer, you should make sure the write speed and read speed of the disk are fast enough. As the video resolution has developing from SD, HD (720p, 1080p) to 4K (2160p), even 8K, the size of a video becomes bigger and bigger. Is quite useful to quickly get your answers and guides.Many people like shooting videos with a digital camera (DC or DV) or a smart phone. Now I know what can I do with these drives and what I can’t. This can prove that a USB3 RAID0 is really possible and even decisive when your purpose is to edit video.Īll the tests were performed using a 5GB load, the RAID was created with a 256K chunk size (since this is for video a large chunk size is needed) And as the math implies, with RAID 0 and 2 drives you should get double the speed (varying on conditions and chunk size right?) Happily this happened and I measured around 370MB/s (2.96Gbps). Then, my MBP SSD measured the nice speed of 640MB/s - But that’s an internal SSD, quite utopic isn’t it?Īfter creating the RAID 0 using two P’9233 drives, I measured it again. Where all my drives measured their “top” speed at around 75MB/s write. I also noticed that using a Kanex Thunderbolt Adapter to USB3.0 kinda stabilizes the drive, operating at its full speed. This drive is a desktop one, my other portable USB3.0 Drives (WD Elements, Porsche P’9220, etc.) gave me a poor measurement of 20-70 MB/s on write, being the LaCie (P’9220) the fastest with 76.4 MB/s and 26MB/s the slowest (WD Elements). (This translates to 1.4 Gb/s, where is USB3 spec of 3/5Gbps?) They are operating on the board controller and for most use is quite enough. I tested them alone, giving me 180 / 190 MB/s for Write/Read respectively. I created the RAID using two LaCie Porsche P’9233 3TB Drives. The answer?… wow! - Very useful to prove theory. I was wondering if a USB3 RAID 0 would give any improvements and if it would really be worth it or of any use creating a RAID on USB3.0 on a MBPr (Late-2013, Qi7/16/SSD).įound some stuff on internet and then this one. I spent quite some time trying to think about the proper configuration for my Hard Drives.
