(Apple’s fusion drive has a 24 GB SSD in the 1 TB model, but the 2 TB and 3 TB drives have 128 GB SSD.) The drive copies the most frequently used files to the flash storage, so they can be accessed more quickly. Hybrid drives combine a standard hard drive with an SSD element, usually from 6 to 128 GB. There is another kind of drive that combines the two technologies: the hybrid drive, or what Apple calls the fusion drive. Currently, you can buy an 8 TB external drive for less than $150, whereas that amount of money will only buy you a 500 GB SSD. However, SSDs are much more expensive when you look at the cost to storage ratio. SSDs tend to be more reliable overall, and if they fail, you can still read data (unless the actual memory chips are damaged), whereas you may not be able to do this with a hard disk. If you drop a laptop when its hard drive is spinning, the drive can be damaged, and you can lose data. SSDs also use less power, run cooler, are lighter, and have no moving parts, which makes them ideal for laptops. SSDs are compact, quiet and very fast, especially when you start up a computer or wake the computer (hard disks may go to sleep when not used for a certain time, and take a few seconds to spin up).

(You can also buy them in 2.5″ format to install in a laptop, or in an external enclosure.) When they’re built into a computer, in appearance they’re just a few chips on a circuit board. Solid state drives, or SSDs, use flash memory to store data.
This latter point may not bother most people, but I prefer not to hear anything spinning in my Macs. They are also heavier and they make noise. As a disadvantage, however, they have moving parts, which means they are susceptible to failure if something goes wrong or if you drop a laptop containing a hard drive.
In terms of cost for storage, hard drives are the cheapest. Disk manufacturers have released drives that are 10 and 12 TB, and we should even see a 16 TB hard drive later this year. This disk was a lot slower than current hard disks, spinning at only 2,744 RPM.Ĭurrent hard drives generally spin at 5,400 or 7,200 RPM, though there are some that are faster. (Performance is not just about speed, there are other features that can make a drive read or write data faster.) From the limited 20 MB storage devices sold in the 1980s, we have gone to the relatively common capacity of 4 TB (even 8 TB for hard drives). Of course, they weren’t always cheap. In 1985, Apple sold a 20 MB hard disk for the astounding sum of $1,495. They are reliable, have large capacities, and are relatively inexpensive. Ignoring the rise and fall of the floppy disk, for a long time, hard disks were the most common storage devices. In this guide, you will learn what the difference is between the different types of drives as well as the advantages and disadvantages of each. You might be curious to know, what’s the right hard disk for your Mac? Choosing which drive to use in a computer involves a trade-off between speed, capacity, and cost. And you can buy external or internal drives of three types: SSD, hybrid (fusion) drive, or hard drive.

Macs are currently sold with three types of storage devices: hard drives (only in the base 21.5″ iMac and Mac mini), SSDs, and fusion drives. An iPhone or iPad contains flash memory, and a desktop or laptop computer contains either a solid state drive (SSD), which is flash memory, or a hard disk.
