There are a lot of scenarios and operations of the OS and of applications that will access external drives directly or indirectly (a simple enumeration of connected USB devices leads to a drive spinning up). So, my final words on this (I promise to be quiet after that ):Ī trusty hard drive will slow down any system up to a temporary halt if it has stopped spinning and it is being accessed in that state. The chip is designed to interact with the internal components of new Macs in order to provide security features and to a lesser degree to take workload from the CPU for specific tasks. The T2 chip will not do any good in this case. If it happens with a freshly formatted drive then it is the way your MacOS installation works. That’s why I thought this is related with the way MacOS works and that it may be impacted by the T2 chip. Everything goes to SSDs for fast local data storage, NAS storage for high amounts of data in your LAN and of course WAN cloud solutions. In the long run, everything gets transferred to my NAS and I am fine accessing it even via WiFi (file transfers between 30 to 50 megabytes per second).īecause of the fact that external spinning hard drives are on the way out, I do not expect an improvement of this issue. When I am actively working on stuff that needs high data throughputs like editing video, they are located on the SSD. My solution is to only have SSDs connected to my iMac via Thunderbolt. I do not know any operating system that has no issues with external spinning hard drives connected via USB. You will experience the same problems with a PC running Windows when having a spinning hard drive connected via USB. Otherwise, you will keep running into slowdowns. A connection like that is crazy fast.īe it as it may, if you do not want to be slowed down using an external USB spinning hard drive connected to your computer you will have to make sure that the hard drive keeps spinning as long as you use your system. With the release of the new Mac Mini, we even see 10Gbe solutions on a “little” Mac. If you have a good NAS that contains a RAID connected to your Mac using a very good WiFi connection or even better an Ethernet connection you really should not have performance issues. I have to admit that this topic is not an easy one. I also tried to go the NAS route, but the performance was really disappointing. The NAS’ system will do a way better job providing you with constant availability and a RAID will perform way better than external hard drives.Īs far as I know, the T2 chip will not have any effect on the speed and sleep and wake behavior of external storage devices. If you really need 8 TB of data connected to your Mac consider using a NAS. It is like day and night in comparison to a spinning drive. If possible buy yourself an external SSD drive connected via Thunderbolt/USB-C and work from there. Something like that should not run 24/7, I guess. I have not tried it but it basically prevents external spinning drives from going to sleep by constantly “updating” hidden files. But that is very rare.Ī different solution might be to use a tool like this: If you have a tool to access the hard drive’s energy settings you may be able to change the settings. When the Mac requests the hard drive to wake up, it needs to get spinning again and here comes the beachball. If a hard drive decides to go to sleep it will go to sleep. Some of them do a good job, others are bad in managing themselves and “understanding” the connected system. They have firmware on board with energy management. This is because hard drives act on their own. External spinning drives will slow down your machine significantly. And there is not very much Apple can do to improve the situation. Probably though, the problem is not the iMac. That is one first step that can be done easily. Disable “Put hard disks to sleep when possible” if you have not done so already.
