Data is saved to directly to cells increasing the speed from HDD technology by 5x. This kind of technology is also used in USB drives or “flash” drives. As mentioned earlier, SSDs save information using NAND flash memory.

How fast your hard drive can spin determines how fast your hard drive can read and write data. Its performance is measured in RPM, or the discs’ rotations per minute. It’s built with a head attached to an arm that reads/writes onto a stack of spinning discs using magnetism. Its many moving parts are also more prone to failure. The HDD is the most common type of hard drive to be found in a Mac computer. It is has a motionless mechanism using NAND flash based memory. The newer version of the hard drive is the SSD, or Solid-state drive. This mechanism is an older version of the hard drive. In the most basic sense, a HDD, or Hard Disk Drive, is a spinning disk drive. Whilst memory is an extremely important part of your computer’s potential to run multiple programs at once, your hard drive is in control of writing and storing permanent data.

If you think it’s only to do with RAM (or working memory), you’re missing out on a large component of your computer’s behavior. We’ve explained before when to upgrade RAM memory in a Mac now, we’re here to cover some details needed in order to consider upgrading your Mac’s hard drive.

No computer is perfect though, and it’s a well-known solution to upgrade any computer that isn’t working to par with its expected performance. From the to the chip-based storage to their titanium casing: Mac computers are made to last. While there are many reasons to be in love with your Mac computer, one of our favorite reasons by far is the life expectancy.
