Blackmagic Raw Speed Test Download Mac ((EXCLUSIVE))
Halima Leisch
I got a new MacBook Air M2 recently, so I ran the test, I supposed it will stop after a few tests and give me some analysis, but it didn't, it ran around 5 times before I stopped it, did my ssd get any damage?
Hi, FWIW, since I'm on the PC and with an internal four disk software RAID 0, although Black WD as Yours: with the BM Speed test I get 530ish MB/s read, 540ish MB/s read, more or less twice Your benchmark, which sounds fine since my stripe has twice the disks; with a couple of two disk hardware RAID 0, both external SATA with slower Seagate disks, I have some 200 write, 230 read on a box, and 225 write, 215 read on the other one, I guess depending on the external enclosure used, and still close to Your results.
On the supply side, the stat of interest is the minimum, not the average sustained throughput. HDD's magnetic head move across platter shaped magnetic material. The heads have to move less near the center of the platters compared to the outer edge of the platters for any volume of data. Consequently R/W speeds are much higher for empty HDD than most full ones. All the more so if the data isn't in large contiguous blocks. SSD don't contain moving parts. They should have the same throughput for all parts of the drive.
After comparing speeds, I'd say that a two mechanical disk stripe is OK for HD, it won't be fast enough for 4k. Of course with SSD drives it's different, the thing is that they provide plenty of speed, but are limited in size, and the bigger the disk, the more the cost. They are a blessing in 4k-8k workflow as for speed, but they hardly provide the needed room, unless You invest four time as much as for a comparable mechanical drives setup. I have 16 TB always on, and 16 more for backups, made of 2 TB drives striped, that's 16 drives, how much will that cost with the SSD prices for 2 TB drives ranging anywhere from some 300 euro for the low end, up to 450 euro for top of the line drives? At the moment I do not see them as a feasible option for gigs with plenty of high resolution footage, unless it is not linked, it's stored somewhere else, and the workflow is edit at low res and conform later.
Blackmagic 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.
If I run BlackMagic disk speed test on a local folder I can get impressive speed results (2000MB/s read/write).
I've been curious to test it on a remote tmp folder and I see slow results (40MB/s read/write).
In order to assist you further on this we need to analyze the subsystem report and the Black Magic speed test screenshots. Please create a web support ticket in suppport.promise.com by registering the product with the unit serial number(Located at the back of the chassis)and attach the files.
I have been having the same issuses with my Pegasus R8 48TB RAID5. I have it plugged into the ASUS TB3 Card and am not getting fast speeds at all, struggling to get through FULL res 8K RED footage. As where another editor I know says hes chewing through the footage on almost an identical setup.
You have two methods to know the performance of a hard drive. One method is to check the read & write speed from its website, while the other is to perform a hard drive test with a piece of disk benchmark software. There are various hard drive benchmark tools on the market. Blackmagic Disk Speed Test is one of them. To get more details about it, pay attention to the section below.
Being a part of Blackmagic Design, Blackmagic Disk Speed Test is used to measure and certify the performance of your disk with a standard method. It only fills in the free space on the disk with a sample of data and then assesses the read and write speed of the disk.
Step 8: After you click on the Start button, Blackmagic Disk Speed Test uses large blocks of data to write test disks and then displays the result. The program will keep testing the write and read speed of your disk, so you can evaluate its performance and readability.
As a comprehensive partition manager, MiniTool Partition Wizard also allows you to benchmark partitions/disks. It can be used to test various connected storage devices on the Windows PC. To be specific, it enables you to perform a hard drive/SSD speed test, USB speed test, SD card speed test, U disk speed test, etc.
MiniTool Partition Wizard is a free disk benchmark tool with multiple configuration options. For instance, it offers you options to set transfer size, queue number, cool down time, thread number, total length, and test mode (sequential, random, or sequential & random).
As its name indicates, AS SSD Benchmark can test the speed of all installed SSDs on the computer. To help you know the performance while the hard drive copies, reads, and writes data, it performs three separate tests. In addition to that, it also determines the access time of an SSD.
UserBenchMark is a free all-one benchmark tool, which can test the performance of CPU, GPU, SSD, HDD, and USB drives. After it finishes the test, it compares results with other users and tells you which part you can upgrade and the expected performance enhancement.
HD Tune is a feature-rich hard disk/SSD benchmark and diagnose tool. To be specific, it is capable of scanning for errors, testing the performance of disks, erasing disks securely, checking the health status (S.M.A.R.T), etc.

In this scenario I achieved average speeds of 336MB/s write and 365MB/s read, far from ideal, but not really down to the cards themselves. This increased significantly when I plugged the reader into the on-board Thunderbolt ports as it jumped to 498MB/s write and 842MB/s read.
I did also try using my Hyperdrive Thunderbolt dock with USB-C and this gave a write average of 480MB/s write and 934MB/s read. The stated sustained speeds of these cards are 400 MB/s write and 1600MB/s read, so it looks like I was being held back here by the card reader, mainly in terms of read speed.
As a result I purchased the Prograde card reader (121.97) which uses Thunderbolt 3, hoping I would see a signifiant speed increase in terms of at least in terms of read speeds. After connecting it up this new one zipped along, reporting an average of 1490MB/s read and write speeds averaging at around 424MB/s. With this reader I also managed to get peak speeds of 700MB/s and writes of 1500, with small file transfers.
As usual the devil is in the detail and card speeds are only one side of the equation, interface choice is key here. If offload times or the speed of the drives you are copying too are not a consideration then the cheaper Sabrent card reader works fine. If you need the speeds and the associated time saving then you will need to look at a faster reader than one with a USB-C 10Gb/s interface.
I could use some feedback or even suggestions on how to improve things. I set out today to do some disk speed tests to show how much improvement my DYI Ryzen "bad-ass" server (at least in my mind) is compared to my old QNAP. Well, I was dealt a blow in this challenge and found that the factory QNAP seems to outperform the Unraid server.
So let me explain my setup and testing. I have three systems, a Ryzen Unraid server (primary server), a Qnap Unraid Server (backup server), and a QNAP test box that is factory standard. In my tests, I used my Mac to connect to SMB shares on all three boxes to a share that uses the cache drives. Docker/VM service was also disabled. I also was hard-wired to my 1GB network stack. During the test, I downgraded my two unraid boxes to 6.7.2 and tested and then brought both back to 6.8. I used two applications that I found, and they seem to track NAS performance decently. The tools are HELIOS LanTest and BlackMagic Disk Speed Test. I broke down the details of the servers and then included a screen-shot of the combined test results.
What I see from the results is regrettably that the factory QNAP has better results than all other setups in most cases. Secondly, I also see that 6.7.2 comes in a strong second. Maybe my testing is flawed or my setup. I also realize there are different drives in the QNAP's than the Ryzen server, but arguably, the backup server and QNAP test box should perform close to each other, right? I will say I'm still happy with Unraid and its flexibility, and it works for my needs (except the recent slowness in Plex after the 6.8 upgrade). So my question is this, are others seeing similar results?
I must admit I don't know much about QNAP, and you haven't told me enough about your testing to make much sense of it. How is cache even involved? If this is strictly a transfer test involving only cache, why didn't you make that clear? If it isn't only about cache, then what does cache actually have to do with the testing?
Yes, and realize Unraid's primary design criteria isn't speed. But I had thought (maybe incorrectly, without facts) that it would still kick a Celeron QNAP's butt. Also don't expect the performance that I would get from our SAN that runs my employers data center.
