Fusion Drive Vs SSD: Pros, Cons, Comparison and Which You Should Get

For a long time now, whenever someone decides to buy an Apple device, there are not many customizations available but one thing that they always have the liberty to choose is the storage and storage capacity. For example, a person can choose to buy either the iPhone 13 Pro Max with the 256GB or the 512GB.

This does not only apply to iPhones but almost all the other Apple smart devices like the iPad, Mac, and iMac. Taking on the iMac into consideration, there is always confusion on what type of drive to go for when purchasing the device and the two types of drives that always come to mind are Fusion Drive and SSD.

iMac is an all-in-one computer series under the Apple brands, and it is regularly updated with new processors and specifications as time progresses. When in need of a desktop computer with some of the up-to-date features and amazing performance, then iMac should be on the list of your considerable devices.

Apart from all these amazing specs and features, the decision to go for either fusion drive or SSD is very important since it will have an impact on the performance of your iMac. Just like any other two competitors, both the fusion drive and SSD have their own pros and cons. 

To help you make the decision yourself, this article is going to give you all the information you need to know about both drives, and afterward, you will be able to make the decision on which one to go for yourself.

What is SSD?

Solid State Drive (SSD) is a storage device that uses integrated circuit assemblies to store data persistently, typically using flash memory, and functioning as secondary storage in the computer storage hierarchy.

Basically, SSD performs the same functions as a hard drive, but instead, data is stored on interconnected flash memory chips that retain the data even when there’s no power flowing through them. Simply put, SSD is just like a USD drive but faster and more reliable.

What is a Fusion Drive?

A Fusion Drive is two separate drives fused together. It is comprised of mainly a Serial ATA drive (a regular hard drive with and a solid-state drive (SSD). The name fusion drive is used mainly in devices manufactured by Apple like the iMac.

In the fusion drive, together with a high-capacity hard drive, dedicated storage space is available, and this uses the SSD. Some of the information like the frequently used information is stored on the hard drive, as the frequently accessed documents are stored on the SSD.

Pros and Cons of SSD


  • SSD offers you the best-level speed and performance. If you are a professional, you should be concerned about this.
  • SSDs does not make noise, i.e., it operates silently
  • It consumes less power
  • It does not heat up your device
  • Good for demanding tasks like video editing and gaming
  • The booting time of an SSD is much shorter
  • SSD in iMac Late 2015 Edition is 2.5x faster than previous versions according to Apple


  • SSD is relatively expensive as compared to other drives like hard disk drives (HDDs)
  • The maximum capacity is very low. For example, the maximum SSD you may get for your iMac is 1TB (this is subject to change as time progresses)
  • SSDs have a limited lifespan. This means that the number of years they can run smoothly is limited. Currently, the estimate for SSD is 10 years, although the average lifespan is shorter. The lifespan mainly depends on the size of the drive and the manufacturer.

Pros and Cons of Fusion Drive


  • Fusion Drives are relatively cheaper than SSDs although they are expensive than hard disk drives (HDDs)
  • Fusion drives are a little silent as compared to traditional hard disk drives. But is not silent either
  • Fusion Drives does not affect user experience (UX) or load times since they work in a logical manner
  • There are higher capacities of fusion drives available to choose from. The most popular ones are the 1TB and 3TB sizes
  • They have better boot-up time than HDDs


  • They may create some noise
  • Fusion Drives have lower RPM. RPM shows how many revolutions a computer hard drive makes in a single minute
  • The operation of the fusion drive is not up to the committed SSD scenario
  • They are available only in certain Macs

Comparisons and Which You Should Go For?

Looking at the pros and cons of both drives, it is obvious that they all have their superpowers at one point or the other. Therefore, before you go ahead to choose which one you want to buy you might consider the following.

Function/DeviceSSDFusion Drive
PriceRelatively expensiveRelatively cheaper
NoiseDoes not generate any soundMakes noise sometimes
CapacityHas low capacities availableHigher capacities are available
LifespanShort lifespanThe lifespan might be shorter if you drop it
PerformanceFast performanceNot the very best performance

The decision to go for either an SSD or fusion drive should be based on the main comparisons above. SSD is a very good option to go for if you have the money to buy them, but you should also consider the limited storage capacity available. If you don’t have the money to afford SSD then you should go for Fusion Drive since it is relatively cheaper and comes with higher storage capacities available.

Anyways, the final decision should be made by you yourself. This article just served as a guide to give you some information about both drives. Hope this article was able to serve the purpose for which it was written. Use this as a guide and make sure to share this with your friends and loved ones.

Are fusion drives really that bad?

No. Fusion drives have some cool features which make them one of the best. All these features have been shown in this article.

Can I replace my iMac hard drive with SSD?

Yes, you can replace the hard drive of your iMac with SSD. But you need a certified Apple dealer to be able to do this for you since it is a little complicated.

Does Apple use SSD or HDD?

Apple provides its users with SSD storage of different sizes. The available storage spaces Appler offers are 64, 128, 256, and 512GB.

How much SSD size do I need?

There is no particular size you should go for on your device. The decision should be made based on the size of storage you will use on your device. To be on the safer side, as long as you have the money, you should go for the bigger size.
