![]() The people who were likely to notice any issues in data transfer speeds were buying different Macs. None of those were pro-level machines - and I'll argue that the 13-inch MacBook Pro isn't really a MacBook Pro until the cows come home. Remember, the impacted machines were the 13-inch MacBook Air, the 13-inch MacBook Pro, and the Mac mini. And the people they were aimed at? They weren't moving data around at enough of a clip to even notice. Because as people who actually bought the machines would attest, none of this actually mattered because these M2 machines were still blindingly fast. Is it really a problem, though?Įxcept, it shouldn't have. Tests run by Max Tech suggested that the M2 Macs were around 50% slower reading and around 30% slower when writing data than their M1 counterparts.Īnd that's when the internet lost its mind. So how much slower were the new Macs with their single NAND chip? Well, quite a bit. But they're beyond the scope of this rant, so we'll move on. It's slightly more complicated than that, and the internet is your friend if you want all of the nitty-gritty details. Having more storage chips allows macOS to read and write more quickly because it isn't constrained by how quickly a single chip can process that data. The M1 Macs, for completeness, were using two 128GB chips to get their total 256GB of storage. Upgrade the storage to 512GB or more, and Apple used 2 x 256GB NAND chips (or larger) to get the job done and boom - things were fast again. And that's when we found out that Apple was using a single NAND chip for storage on the 256GB versions of its new M2 Macs. YouTuber Max Tech set about ripping its 13-inch MacBook Pro apart to get to the bottom of things. Reviewers found that those who had been sent the base model of their respective Macs were seeing slower transfer speeds than those whose Macs had upgraded storage. That tool is designed to see how quickly a Mac can read and write data to its storage. They weren't all that fast when put through their paces using tools like the Blackmagic speed test tool. ![]() The Macs had great displays, and their batteries could last for actual days, not hours, depending on usage. When they did, everyone marveled at just how fast those M2 chips were. But that was pre-M2, and before the M2 13-inch MacBook Pro and MacBook Air launched. And also for remote collection of such data by admins, who could use this feature with ARD or other secure command line login.There was once a time when nobody cared what storage configuration Macs had so long as they had enough of it. The ability to run Disk Speed Test from the command line would allow for automation. Something that one could import into Excel or some other spreadsheet would be idea. It would be nice if Disk Speed Test had an option to save a log file with the test results for each run. It would be nice to be able to specify a pause between runs. 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 Blackmagic 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 Blackmagic select the disk image mounted. Mount the volume (if it is not already mounted). Make it big enough for Blackmagic 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 Blackmagic 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. Blackmagic is now faster enough to rate internal SSD speeds, even the Startup Diskīlackmagic has been updated to adequately report the speed of SSD devices. ![]()
