If you haven't experienced the delicious speed of internal or external solid-state storage, you just don't know how swift and smooth your Mac computing experience could be!Ģ022's Top Performing Internal Drives These 2.5" SATA III interface drives feature the latest cutting edge controller chips and flash memory from Samsung, Hynix, Indilinx, Marvell and others. Starting up your Apple computer, launching apps, backing up your data, or installing programs and updates on an SSD happens in typically a fraction of the time. The performance benefits of running your Mac on a solid-state disk are dramatic. Currently manufactured SSD's in 2022 are now easily 4x to 20x FASTER than the fastest spinning platter hard drives available. For Test 6, although the Photos app was installed on the external SSD, the 380GB Photos library was stored on the internal 5400rpm SATA hard drive.Flash memory SSD drives for Macintosh are now the de-facto future of computer storage. Each time tests were run, they were run after a fresh reboot.Ĥ. All tests performed three times and the results averaged.ģ. macOS and all apps were installed on the external SSD.Ģ. Test 6: Launch Photos app with a 380 GB Photos library:ġ. Obviously, your results will vary depending on the software/login items/fonts/kernel extensions you have installed.īelow are the results of my testing. mid-2017 Retina 4k iMac with 8GB RAM, a 3.0 GHz quad-core i5 CPU and a 5400rpm SATA hard drive). The tests were performed on the same model iMac as yours (i.e. Today () I installed macOS Sierra 10.12.6 on an external SSD (specifically a 500GB Samsung T5) and did some comparison tests to try and provide an indicative idea of the type of speed improvements you could expect. Let me know if you have any questions or would like to chat about doing an internal upgrade. However, I’m guessing this isn’t something you’d want to tackle (I wouldn’t recommend it unless you’re very comfortable with the idea of doing it), but if you are I’m more than happy to chat to you about it. I upgraded the same model before Christmas so that it had an internal SSD for storage and a lot more RAM. While this iMac is not officially upgradable after purchase, it can actually be done.

To install macOS you will need to reformat the drive so that it’s formatted as a OS X Extended (Journaled) drive and that its 'scheme' is GUID Partition Map.If you opt for a 500GB external SSD instead of a 1TB one, you may want to consider having your Photos and/or iTunes libraries stored on your internal hard drive instead. Once set up and running okay, you can use the internal hard drive as storage.The main thing is that you have enough space for your macOS installation and all your apps. You don’t necessarily need to buy a 1TB model (although this would be ideal).Once you have the drive you want, you will need to install macOS onto it and migrate your data. Some examples of the types of external drives I mean are:
And remember, it needs to connect to one of the two Thunderbolt ports (not one of the USB ports). Do not get confused by USB 3 - this is not the same as USB 3.1. However, you’ll probably find Thunderbolt models are too expensive, so opt for USB-C / USB 3.1. USB 3.1) as its interfaceīoth of the above are critical if you’re wanting to improve speed. it supports either Thunderbolt or USB-C (i.e.it’s definitely an external SSD (and not just a hard drive).
Since your iMac has two Thunderbolt 3 (USB-C) ports that support speeds up to 40 Gbps (via Thunderbolt) and 10 Gbps (via USB 3.1 Gen 2), the easiest solution is to use an external SSD that’s connected via one of these ports and to install macOS on that and use that drive as your main boot volume. To fix this you really need to address this bottleneck. Your mid-2010 iMac would have had a 7200rpm Hard Drive. Your iMac has a 1TB 5400rpm SATA Hard Drive and this is what’s causing the bottleneck.
