SSD Vs Fusion Drive

SSD Vs Fusion Drive is the main confusion for those people who want to buy an iMac. While buying a Mac device you don’t get many options, except in storage category. So example, if you are buying a MacBook Air, you can choose between the 128 GB and 256 GB variants. However, when coming to iMac you get many better choices.

While buying an iMac, you have two option to choose between SSD and Fusion Drive. Both have advantages and disadvantages; so you should select wisely. And, I’m here to help you with the all information that I have. In this article, I will compare SSD and iMac Fusion Drive.

So, let’s start with an comparison.


For better understanding, I will explain everything in reverse manner.

Flash Hard Drive

Flash Hard Drives are also known as Flash Drives. This type of storage mostly seen in Ultrabook and other high-end laptops. You can see such drives on MacBook Air or MacBook Pro. You cannot do comparison between Flash Drives and SSD’s. Now the fact is, SSD’s are using Flash Storage, for better  boosted performance. When you hear an Mac has Flash Storage, it means that iMac has SSD Storage.
In short, Flash Drive based iMac have one SSD for all storage purposes. As compared to HDD, these devices offer excellent speed, performance, stability, and durability. Believe me, SSD works better with iOS devices.

Fusion Drives

Basically, Fusion Drive is actually a hybrid hard drive. Here logic is simple,  Apple combines an HDD and Flash Storage Drive. If you take case of iMac, you can choose a Fusion Drive of 1 TB to 3 TB size. there was 128 GB of Flash Storage along with 2 TB Fusion Drive in year 2015. Apple had made announce about. HDD and SSD merged into a single storage device, which will be then control by the Mac OS. But for now, this option is available in iMac only. But, For others, you have to select between SSD or HDD.
Flash Hard Drives- Advantages and Disadvantages
Flash Drive or SSD’s have any advantages. Some of features I have mentioned below. These advantages are more than enough for better speed and performance.
SSD’s offer the best-level speed and performance.

Booting time of Flash Drive based device is very short.
>They don’t generate any noise.
>They consumes less power.
>Your device doesn’t heat.
Suitable for heavy tasks like video editing.

With advantages, there are few cons too. Some of them are:

Flash Storages are very expensive, that not everyone can afford.
> You will get maximum Flash Storage is 1 TB.

Fusion Drives- Pros and Cons

Fusion Drives are better replacement for Flash Storage option. their pros are as follows. These pros are found when compared with SSD’s and traditional HDD’s.

Fusion Drives are much affordable than SSD’s. But  fusion drives have a higher price than HDD’s.
As compared to traditional HDD’s, Fusion Drives don’t make more noise – that doesn’t mean they are silent.

You will get Fusion Drives in higher capacity like 1 TB, 2 TB and 3 GB fusion drives in iMac’s.
>It works better without affecting user-experience.
>Fusion Drives have very short bootup time.
There are a few disadvantages also.
>Fusion Drives create little some noise.
>The performance is not that good as compared to SSD.

Before we get into conclusion, you should know the working of Apple Fusion Drives.

How Does Fusion Drive Works?

As I said earlier, it combines SSD and HDD, to form a single memory storage device. The capacity of SSD is lower than the HDD. the iMac 1 TB Fusion Drive of 2015, you would find 24 GB Flash storage. the overall working of Fusion Drive is based on your usage. SSD part will be used for storing purpose, to  frequently accessed files. For example, if you have some imp document files that you open daily, they will be stored on the SSD storage. This transfer is very quick.

Suppose if you are using one software called iMovie for editing videos, almost daily. In this case, the Mac OS system will movie iMac software into SSD storage. So, the next time you open it, you can have excellent speed for sure. Fusion drives provide a excellent speed and performance than HDD, but not much as compared to dedicated storage devices. You cannot expect the less booting-up time or writing speed in a Fusion Drive and SSD storage.

I will recommend you, go for dedicated Flash Storage, if you want better performance and speed. You will have to spend more money for dedicated Flash Storage. You can consider Fusion Drives, if you don’t have much money to spend on SSD. You wont get best speed and performance, but still, its better than the HDD.

Another better solution is that, get an affordable SSD storage and get external HDD. You can opt external SSD with better speed and higher price. But the overall cost will be lower than a 1 TB SSD. While selecting an external hard drive, you can go for noiseless high performance and USB 3.0 HDD. This is how, you can actually save a your money.


See, decisions is very simple. If you want better performance, you should go with SSD. Of course, you need to spend more money for the lower storage. But it makes sense than going for a average performance Fusion Drive.
And if you don’t  need much performance, you can go for Fusion Drive. Also, you can get an SSD and also keep an external HDD connected. In the end, I hope you have found the answer in this article.
