Why your next laptop should have an SSD?

Professional laptops have undergone an important evolution in recent years and SSD units are a perfect example of how a technological leap can influence the experience of the end user.


An SSD, or ‘solid-state drive’, uses a printed circuit board (PCB) with NAND flash memory chips and a controller to store data.

Unlike traditional hard drives, SSDs lack moving parts, are more energy efficient and generate hardly any heat; these characteristics translate into important improvements at all levels, which we will detail in this article.

1. Greater energy efficiency and portability

SSD units function more efficiently and consume less energy than mechanical hard drives. On average, the best SSDs consume between 2 and 3 watts while second-tier models reach 6 or 7 watts.

In a professional laptop, this may entail up to thirty minutes of extra battery life, a figure that obviously makes an important improvement in the portability of the device.

2. Better performance and shorter boot and shutdown times

Traditional hard drives (HDDs) function via a moving head that carries out reading and writing operations on the platters that serve to store data.

On the contrary, SSD units lack these moving parts and the data are stored on and read directly from the memory chips. This allows even basic models to reach read and write speeds that may treble those of hard drives.

Thanks to that greater velocity, operations are carried out much more quickly and load times are improved, including those of startup, shutdown and wake up from sleep.

If, on average, a laptop with a normal HDD can delay some 40 seconds in booting up, with an SSD the time is 15 seconds.


3. Reduced heat and improved durability and reliability

As they lack moving parts, SSDs are both more energy efficient and generate less heat than hard disks. This is especially important in ultralight devices, where design and internal structure play a fundamental role and each component counts.

They are also more resistant to shock, vibration and shaking, and have no problems when exposed to electromagnetic sources.

To all this we must add that an SSD has an average lifespan of 2 million hours of use before a fault occurs, compared to HDDs with 1.5 million hours.

In conclusion, thanks to these storage units based on NAND flash memory chips it is possible to create professional laptops that are lighter and more efficient, reliable and powerful.
