Hi, I have a MacBook Pro 15" (Mid-2014) (Core i7, 16GB RAM & 512GB Internet SSD), running the latest version of MacOS Mojave - 10.14.2. I would like to run 3 simultaneous Virtual machines: 1x running Windows 10 1809 (including Microsoft Office 2019, Visio 2019 (and maybe Project 2019), and Visual Studio 1x Running Windows Server 2016 which will run SQL Server 2017 Developer Edition 1x Running Windows Server 2016 and IIS. The two VM servers will be run as a development environment as a project for my current studies. Shall I run the Virtual Machines from the external same SSD (connected with USB3.0)? Or shall I dedicate another additional External SSD? I am asking whether this will have any negative impact on the VMs performace, not from a storage space aspect... I am using the below SSD Caddy - https://www.amazon.co.uk/gp/product/B00XLB0EOW & a Samsung EVO 860 - 512GB SSD. Thanks!
It's up to you. You can use any discs. But please check the speed and type of connection which you prefer. Let us know if it's not that case.
