Also known as flash drives, SSDs store information on microchips and have no moving parts. In simple terms, SSDs are much faster than traditional HDDs. What’s the difference between SSD and HDD Mac hard drives? The quite obvious tradeoff here is that you have to carry external hard drives around with you, unless they are purely used as occasional backups. It’s also a good way to transfer files quickly between devices, including between Macs and PCs - although this is generally best reserved for large files.įinally, external hard drives are great for making backups of your files so that they are physically isolated from your device - this is a good measure of security because your primary drive could become compromised. You can upgrade them, but Apple makes this both difficult and costly. MacBooks, in particular, often come with only 128 GB of Apple hard drive storage. The most obvious reason to use an external hard drive over and above your existing one is to extend limited storage capacity - something which has ironically become smaller over the years thanks to the SSD technology.

However, over the past decade, internal Hard Disk Drives (HDD) became bigger, cheaper, and faster to the point where needing an external drive for Mac was unnecessary for most users - until a new standard of technology was released with the Solid State Drive (SSD).
