I regularly have at least 8-10 apps open at all times, Firefox browser with at least 200 tabs open, Mail, Keynote, Numbers, Pages, Zoom and various audio apps (Logic, ProTools or Live, Loopback, Dante etc.) which I use for lecturing. I started on Mac OS High Sierra (I generally try to be 2 Mac OS behind latest, for stability and compatibility reasons), but I’ve just upgraded to Mojave without any hiccups. To reassure anyone about my present system: I am quite experienced with Mac upgrades and found it very easy to upgrade the SSD on this system (with the right screwdrivers, of course), I’ve been running this laptop flat out for about 6 months now, and it is very, very stable. I have found hardly any information at all about such an upgrade on the web, and before I commit to spend another £500 on an SSD, I’d like to hear from anyone who might have tried the 4TB configuration (8TB is excessive from any possible point of view!) and ask them if they found the system stable. I am aware that Sabrent manufactures both 4TB and 8TB NVMe M.2 Gen.3 blades, which have similar performance to the (excellent) OWC I own and can be installed in my laptop using the Syntech NGFF to M.2 adapter, but I am concerned about thermal issues with a larger NVME blade, and whether this might cause some erratic behaviour when CPU and GPU get going.

My only minor gripe is with the size of the SSD - I’m not going into detail, but I genuinely need to have more than 2TB of SSD internal storage, my old system had 3TB internal storage (after taking out the CD drive), and had it not been that it was getting too old and slow for my needs, I would have gladly kept it just because it was so easy to upgrade everything. This is an excellent system with great performance, and replaced my previous 13” MB Pro 2012. I recently purchased a Grade A used 15” MacBook Pro 11,5 Dual Graphics 2.8GHz 16GB RAM which I have upgraded with the OWC 2TB Aura Pro X2 2TB SSD.
