If you recently bought a MacBook, you most certainly received a solid-state drive (SSD) as the primary boot disk. Larger gaming laptops have also switched to SSD boot drives, while a small percentage of low-cost computers still prefer hard disk drives (HDDs).

Most prebuilt desktop PCs now include SSDs as their boot drive, except the least expensive versions. Sometimes, a desktop computer comes with the HDD as an additional larger-capacity storage drive and the SSD as the boot drive.

How can you decide if you have to choose just one? Read on to learn the key points of SSD vs HDD MacBook and select the one that is appropriate for you:

What is the Working Style of HDD?

HDDs employ rotating platters covered in magnetic material. Actuator arms with read/write heads move over the platters to access data. A motor rotates the platters. The firmware and I/O controller handle protocol management.

Tracks, or concentric circles, arrange each plate. Sectors are the logical units into which tracks are separated. To organize and identify data, a unique address is generated for each track and sector number.

The closest accessible place is where data is written. An algorithm preprocesses the data so that the firmware can identify and fix problems before they are written.

The platters maintain predetermined speeds, which range from 4,200 rpm to 7200 rpm for consumer PCs. These rates are correlated with read/write speeds. A hard drive will read and write data more quickly the higher the pre-set speed. 

Read and Write:

The read/write head collects the data by reading whether a charge is present in each address, and the I/O controller notifies the actuator arm where the data is located each time you ask your computer to retrieve or update it. 

If a data update is requested, the read/write head modifies the charge on the affected sector and track.

Delay is the time it takes for the actuator arm to locate the proper track and sector after the platter starts to spin.


As it takes longer to locate and retrieve data physically than it does electronically, HDDs have limitations related to the mechanical components required to read and write data. 

If the mechanical components are dropped or treated roughly, they may skip or fail. This is a problem with Macbooks because one would carry them often. On the other hand, it could be more significant for desktops. Compared to equivalent SSDs, HDDs are also heavier and consume more energy. 

An HDD’s Advantages:

The advantages of hard disk drives include their proven technology and often lower cost compared to solid-state devices for equivalent storage capacity. Regarding SSD vs. HDD MacBook capacity, HDDs likewise offer greater storage capacity than SSDs.

Understand what an SSD is:

Solid-state drives use flash memory to provide increased endurance and performance. Because your hard drive has several tiny, moving elements, such as spinning platters, spindles, and magnetic heads, it’s simple for something to go wrong, and you could lose your crucial data. 

SSDs operate cooler, last longer, and consume less energy when they don’t have any moving parts. If you lose memory for any unfortunate reason, data recovery services are your best way to recover important data.

Read and Write:

Data updates on SSDs can be a bit tricky. When you modify any portion of a block, the entire block is refreshed. After the previous block is deleted and replaced with the updated version, the old data is copied to the new block.

When data is required, the SSD controller retrieves its charge status. Garbage collection keeps old blocks free for later usage while the disk is inactive. TRIM lessens the wear on the SSD by allowing it to avoid overwriting some data. Wear levelling ensures every block is used equally, prolonging the drive’s life.

For smooth data transmission, SSDs come over-provisioned with excess storage. This concealed storage does not impact available space and helps to preserve performance.


SSDs cost more than HDDs because they use newer technology. Large-capacity solid-state drives can be tougher to locate, but they are catching up. Up to 2.5 times larger HDDs are possible.

An SSD’s Advantages:

What makes a solid-state drive the best option? SSDs load games, apps, and movies more quickly. Because of the technologies they employ, SSDs are lighter and more resilient to jolting and droppage. Moreover, computers can operate cooler thanks to solid-state drives’ lower energy consumption.

Due to its speedier performance than HDDs, an SSD offers several advantages.

How should one choose between HDD and SSD?

HDDs are excellent for:

Storing a lot of data that you use sparingly in backup.

Those with basic requirements for computers.

Budget-conscious PC builders.

HDDs are dependable and more durable when used for extended periods of storage. They work just fine for external backups. HDDs work well enough for standard office duties but need help handling massive files and demanding applications. To manage space, use an HDD cleaner.

SSDs are Well-suited for

Consumers of resource-intensive software, including suites for multimedia editing.

Players of newly released games.

Anybody who copies and accesses files regularly.

SSDs process data quickly, which makes them ideal for demanding jobs and huge file transfers. In 2024, an SSD will be preferred if it is reasonably priced. If your most important Mac data goes missing, you must contact Mac data recovery services.

Wrapping It Up:

Regarding SSD vs HDD MacBook, SSDs are typically speedier and more dependable even though they are more costly than HDDs. An SSD is worthwhile if you require quick boot and load times, enhanced system performance overall, and can afford the increased cost per GB. An HDD can be a better choice if you require more storage at a reduced price.
