Mac fusion drive vs flash drive

And you can buy external or internal drives of three types: SSD, hybrid fusion drive, or hard drive. Choosing which drive to use in a computer involves a trade-off between speed, capacity, and cost. Ignoring the rise and fall of the floppy disk, for a long time, hard disks were the most common storage devices. They are reliable, have large capacities, and are relatively inexpensive. Of course, they weren't always cheap. This disk was a lot slower than current hard disks, spinning at only 2, RPM. Current hard drives generally spin at 5, or 7, 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. Disk manufacturers have released drives that are 10 and 12 TB, and we should even see a 16 TB hard drive later this year. In terms of cost for storage, hard drives are the cheapest.

They are also heavier and they make noise. This latter point may not bother most people, but I prefer not to hear anything spinning in my Macs. Solid state drives, or SSDs, use flash memory to store data. When they're built into a computer, in appearance they're just a few chips on a circuit board.

You can also buy them in 2. 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.

To accommodate all my data, external storage was now a requirement. With this unit, I could transfer the three drives that had previously lived in my Mac Pro, saving the cost of having to purchase new drives. In addition, the ThunderBay provided the fastest possible transfer speeds Thunderbolt 2 with the greatest capacity for future expansion, all via a single compact box that needed only one connection to the iMac. I would have stuck with this setup except for one thing: The ThunderBay is quiet overall.

Depending on your sensitivity, it may not bother you at all. But it is far from silent. Second, the 3. While all of this was tolerable, I wanted better. Better than even the Fusion Drive.

So I looked for another solution. As a bonus, they are a cheaper alternative to the ThunderBay. If you need maximum speed, the ThunderBay remains the preferred solution. Most of the time, the drives would not be in use at all. However, my past experience doing this with other Seagate portable drives has been excellent, so I am willing to take the risk.

So here I am typing on my new iMac.

With its GB Flash Storage, it is both superfast and completely silent. I believe I would have made similar choices as you for similar reasons. I have a lot of video, which I duplicate as a backup, plus Time Machine backups locally and being served to other computers in the house. In , Apple came up with a compromise: As its name suggests, a Fusion Drive melds a hard disk drive with flash storage to provide the best of both worlds.

The user sees just a single volume, but behind the scenes, macOS automatically and dynamically moves frequently used files—notably those used by the operating system—to the flash storage portion of the Fusion Drive for faster access while keeping infrequently used files on the hard drive. In essence, the Fusion Drive provides much of the speed of an SSD along with the capacity of a hard drive.

There are some caveats. But not all Fusion Drives are created equal.
