This is where Wear Leveling kicks in which then can push the heat as well! As a cell which has data that is more worn is transferred to a cell that is less worn. I might add your workflow is also a factor here! Massive data work like video rendering also wears the drive faster! It also requires more housekeeping to keep it running. The other issue is being dust free! A system which is loaded with dust and debris will run hot as the ability of the fan to cool things will be impacted but the junk! The last issue is the battery, surprisingly an old battery or one that is well worn requires more power to charge or hold a charge (adding more heat)! So a system which has a battery over four/five years needs to be replaced as well as one that is getting about 850 cycles or more. I use TG Pro which is one of the best ones out there. Then the question is, is the heat buildup within the SSD bad? As it turns out writing works better when running hot!ĭon't forget we also don't want to cook the rest of the system either! The answer here is just install a good thermal monitoring app which can also push the fans as the temp gets above a level. Here we are dependent on the drafting of the fan to pull the heat away but we don't have an effective means to move the heat away directly from the flash chips or space enough for the mass and in this case a passive fin design for the air to run through to pull the heat away. Think of it this way you have a cup and you fill it with water it can't hold more than what the cup can hold, so once these get to temp you can't add more heat to them and as there is no fins to allow the fans drafting to reduce the heat buildup more quickly you don't really improve things as its not the short hits that we worry about its the long write events. Sadly these M.2 copper blocks only offer the mass and no means to move the heat away. With CPU's/GPU's we can see the full solution a large block of metal to transfer away the heat, a means to move the heat to a set of fins which has a fan blowing across. We often forget the function of a heatsink is two fold: one to offer a mass to hold the heat and a means to radiate it away. So what to do? Laptops don't have the space to add proper heatsinks and the benefit of a heatsink only goes so far. This follows the same problem HDD's a CPU's faced as there density and performance improved they too got hotter. So with two SSD's that use different density of chips of the same logic generation the less dense will run cooler! Likewise an SSD which uses more chips also runs hotter. This gets complicated! The major issue is the density of the flash cells get tighter the hotter the logic runs as you use it. I very rarely get apps to hang and overall found this to be a great rig for a fraction of the cost of a new - A 4TB SSD will in fact run hotter! 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.
