They’re very sophisticated memory chips, connected to equally complex controller circuits which manage the flow of data hither and yon. SSDs comprise memory chips with no moving parts.

More often than not, I’d start to do something, wander off until the Mac mini was ready, then get back to it. Using a Mac with limited memory, slow CPU and a spinning hard drive requires infinite patience. 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. 4:26 AM.Ģ1st-century computing saddled with 20th-century storage Best Buy $129.00 These are quite fast enough.

I can also see that the Sintech adaptor is supplied with the M2 screw that's needed to screw the drive down. I understand that this won't come with the NVMe adaptor? I plan on keeping the 1tb as a time machine drive and just running off the new SSD.
