![]() Instead of just running forever, it would be nice to be able to specify that Disk Speed Test is to run some user specified number of times.Ībility to specify the pause period between runsĪt the default values, it is hard to stop the program after it has totally finished one test, and before it has started another. However, a few enhancements would make this program truly wonderful. You can easily detect when a device is performing subpar and, and with the spinning disk, you can see is transfer speeds deteriorates over time.ĭisk Speed Test is a very useful product and one cannot complain about the price point. I have run the app on USB 2, thumb drives, USB 3, and USB C devices to see if I’m getting my money’s worth. ![]() On an older MacBook Pro the rates I see are 500 MB/S both read and write, as you would expect. I have tried this on my older mackbooks with SSD and they do scale down as the device is older. ![]() On my 2016 MacBook Pro, I am seeing speeds like 1,000+ MB/s write, and 1100+ MB/S read. Since the “volume” is on your Startup Disk, you will see how fast it drive is. In the app select the disk image mounted. Mount the volume (if it is not already mounted). Make it big enough for the app to work with (7+ GB) and name it what you will. Create a disk image (.dmg) using the disk utility specifying file->new image->blank image. I found a workaround that will report the rates of the Startup Disk. When the app tries to read the Startup Disk, you get the message that the device is not writeable, hence you cannot rate the the transfer rates of the drive. The app has been updated to adequately report the speed of SSD devices. Install Blackmagic Disk Speed Test on your Mac using the same steps for Windows OS above.

Download an Android emulator for PC and Mac:.Is quite useful to quickly get your answers and guides. 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. ![]()
