![]() ![]() Of course, Quora has an answer for that, but I wanted to see for myself. The whole purpose of this exercise is that I was wonder if there was any speed difference between the formats on an external SSD. The Mac OS Extended formatĪ quick reformat to Mac OS Extended erases the whole drive. And they might not know what I’m talking about. In fact, often you might be sent an SSD that is formatted ExFAT since that’s often the default and many people don’t bother to reformat then as they might have to maintain compatibility between Macs and PCs. That’s pretty respectable overall for ExFAT as I always expect it to be slow but it really isn’t. That’s not bad for a 2 TB SSD that was under $200.Īnd because I like to time things with a stopwatch I’m copying a 30 GB folder full of video files to the empty drive using my favorite all around Mac app Path Finder.ģ0 GB file transfer to ExFAT format: One minute. This speed test was going to an empty, ExFAT formatted 2 TB SanDisk ExtremePortable SSD For these tests I’ll leave it set at an UltraHD resolution, a 4 GB file size with the codec set at ProRes as that’s a very common video file type that I create, copy and transfer. When I plug it into my iMac Pro straight out of the box it is formatted as ExFAT.įor testing the speed I’ll use the AJA System Test as it’s easy to setup and lets me dial in a specific resolution and codec type. These specific SanDisk SSDs have really come down in price so my guess is it’s the older Gen 2 versions moving out of the market vs the newer and faster Gen 2×2.Īnyhoo… back to the task at hand. And this is a good comparison between these two exact generations of SanDisk Extreme Portable SSDs. Kingston Technology has a good article on this that surfaces early in a Google search as Kingston apparently cares more about educating customers than the behemoth that has become Western Digital (that owns the SanDisk brand). See it says so right in the tiny print on the box.Īpparently there is now a new version of this very drive which is the USB-C 3.2 Gen 2×2 (20Gbps) spec which is double the speed of this Gen-2 without the x2. These SSDs are USB 3.2 Gen-2 (ahh yes the USB standard is so confusing) so they should be capable of 10Gb/s when plugged into a USB-C/Thunderbolt port. Never hurts to have a few of these things lying around. I picked up a couple of the venerable SanDisk Extreme Portable SSDs during Amazon Prime Day this year. I was doing this for my own research so why not post the results? This article isn’t meant to be an educational primer on the differences in these formats (you can find that here and here) but rather just a comparison on file transfer times between some of them. There’s quite a few ways to format a disk on a Mac these days There used to be only a few options for disk formats but if you’re working on Mac OS 10.13 or later there’s an additional one called APFS. That’s a somewhat universal format that is compatible between Macs and PCs and allows for the transfer of file larger that 4GB? which is important. But looking at it in the Disk Utility shows the formatting as ExFAT. When you buy a new external SSD and plug it into your Mac it usually mounts right up. This isn’t the first time I’ve thought about hard drives, drive speeds and SSDs in general. Often I’ll work in entire job off of an external SSD if I have to move it between systems at my home or office or a client facility. Since I’m a Mac user working in post-production I do a lot of file transfers and since external SSD drives have become quite affordable, are fast and easy to ship they have become a medium of choice when it comes to moving files around when an internet transfer isn’t feasible. I have often wondered if the different SSD drives formats really make a difference in speed.
