Starting up and shutting down took a long time too, as macOS handled all that virtual memory housekeeping. Trying to do anything was equally painful – lots of spinning beach balls while the Mac waited for data. Click on an app icon in the Dock, for example, and I’d lose track of how many “bounces” I’d watch until it finally opened. That’s why my poor Mac mini slowed to a crawl whenever I asked it to do something. It does so by pushing off a lot of work to “virtual memory,” which pages information out to storage when not in active physical memory. MacOS is not bad at navigating slower-speed CPUs and limited RAM overhead. A tiny arm outfitted with sensitive electronics reads and writes data sequentially to the disc surface by changing microscopic parts of the surface’s magnetic polarity. Your data is written to a disc of magnetic material that spins on a central motor. Inside each hard drive is a mechanism that looks remarkably like a record player. Different materials, upgrades in mechanisms and capabilities, much better electronics inside, but mechanically similar enough that there’s no mistaking it. The one I disassembled was bigger, slower, noisier, and less reliable than the ones used in computers today, but with the cover off, it looked just the same as a modern one. Hard drives are faster, smaller, and use less energy than ever before, but they’re still essentially unchanged in basic concept from the first refrigerator-sized storage devices that IBM developed for its room-sized computers more than half a century ago.Īlmost 30 years ago I worked for a hard drive company, and one of the first things I did when I started was to take apart a drive to understand how it worked. In the process, Apple sacrifices a lot of performance.Ģ1st-century computing saddled with 20th-century storage It’s little wonder that Apple continues to use them for low-cost, low-margin systems like the Mac mini. The price of SSDs has dropped precipitously in the past few years, but hard drives remain the champion of low cost per gigabyte – a 500 GB HDD replacement for a Mac mini costs you less than $50 at retail, while a 500 GB SSD might cost three times that amount. That’s because Apple continues to offer that model with a spinning hard disk drive, and that murders performance. I never expected it to win any races, but what kills the Mac mini compared to the MacBook Air isn’t the CPU or the RAM. It comes with a 1.4 GHz CPU and 4 GB of RAM. Regardless, I strongly recommend considering it – not just for a 2014 Mac mini, but for any older Mac you’d like to pep up.Īt $499, the base-model Mac mini is Apple’s least-expensive Mac, half the price of the MacBook Air but not nearly as peppy. If you’re using one of these models and you’re looking for a good way to bump up the performance, an SSD is, quite frankly, one of the only things you can do (unlike older Mac minis, Apple soldered the RAM in place).

Unfortunately, an hour of Googling around has met with no joy on that count.I finally got around to upgrading my 2014 Mac mini with a solid state drive (SSD). If it's CL=19 I'll go with the Kingston-recommended modules, but if it were CL=17 I'd probably go for the HyperX modules. So I was hoping to find an authoritative source for what the original-equipment CAS latency was for the Mac Mini.

I'm not looking for extra performance I just want to make sure it's as compatible as possible and not slow it down. I wanted to get memory with a matching latency or perhaps something below. The spec as far as DDR4 2666 MHz 260-pin SODIMM seems quite clear, but I haven't been able to find a CAS latency value for the RAM I'll find installed in the Mac mini.

I thinking to buy it configured with the base 8GB and upgrade it to 32GB with aftermarket memory modules, at a savings of about 50% ($300) from the $600 extra of ordering it with 32GB. I'm researching a memory upgrade for a 2018 Mac Mini (in advance of purchase).
