How SSDs Changed Computing Forever

The Solid State Drive, or SSD, has transformed not only what we store data on but also the computing experience as a whole.

From speedier boot times to smooth multitasking, SSDs have improved everything from consumer laptops to enterprise data centers. In this article we will look at how SSDs transformed computing which we do by looking at their tech pros, practical results and also their role in reshaping user expectations.

The Limitations of Traditional HDDs

Before jumping into what SSDs improved, we must first look at the flaws of the HDDs they replaced. Hard drives use spinning platters and a moving read/write head, which also means that at each step of the process there is physical movement. Although this technology served us for a very long time, it does have its limits:

• Speed bottlenecks: Mechanical components have a slow response time. This causes longer boot up times, slower data access, and latency in multitasking.
• Durability concerns: Since mechanical components in HDDs are in constant motion, they are more likely to fail due to drops, shocks, or wear over time.
• Noise and heat: Driven by motors that produce noise and heat, which affect device performance and energy efficiency.

As we see with the growth of software and operating systems which became more complex, and also in the fact that we have tasks like gaming, video editing, and virtualization which are now common, we see these limitations become more evident.

The Arrival of SSDs

Solid state drives marked a shift from what we are used to in traditional storage. We see in them the removal of moving parts, of spinning disks, and of the time it takes to find data.

The early SSDs were expensive and saw use in niche applications which included military and aerospace. As manufacturing processes improved and flash memory prices came down, SSDs became a viable option for consumer electronics which in turn brought about a large-scale transformation in how we approach computing.

The Speed Revolution

SSDs’ greatest benefit is in speed. We see that a typical HDD reports speeds of between 50 to 100 MB/s for both reading and writing, which is far outdone by even the budget SSD which can reach 500 MB/s and above. At the top end we have the NVMe SSDs that connect to the motherboard via PCIe which achieve several gigabytes per second.

This increase in speed is evident in real-world use:

• Instant boot-up: Operating systems which used to boot in minutes now do so in seconds.
• Faster file transfers: Large files such as movies and games, among others.
• Improved application performance: Programs open up faster and also the transition between them is smoother.
• Reduced load times in games: Levels load almost immediately, textures present right away, and we see a reduced issue of lag related to storage.

This level of speed has transformed user expectations. What used to be an acceptable delay is now a frustration — and we have SSDs to thank for that.

Enhanced Reliability and Durability

Since there are no moving parts in SSDs, they are more resistant to physical damage. You can put a laptop which has an SSD through a drop and report that it has a much lower chance of complete data loss than a laptop that uses an HDD.

They also produce less heat and are more quiet, which in turn makes them the best choice for laptops and compact devices which have issues with space and thermal management. Also in terms of durability they have outperformed which has made SSDs the top choice in many mission critical systems from servers to embedded industrial devices.

Also, SSDs have what is called a predictable wear cycle. Although they do wear out over time, most modern SSDs include wear leveling and over-provisioning technologies which in turn extends their life greatly. For the average user an SSD may last many years with normal use without issue.

Portability and Efficiency

SSDs’ lightweight and compact design has enabled a new class of devices to see growth. Ultrabooks, tablets, and thin and light laptops in large part thank the small size of SSDs for their sleek design.

In terms of power, SSDs outperform HDDs in that they require less which in turn allows for better battery life in mobile devices. We also see this translate to lower energy costs in large scale data centers. Also known for silent operation and performance which is very much in tune with what modern hardware requires.

Impact on Software and System Design

As the rollout of SSDs in more devices went up, software developers had to change. We see that applications are designed for the speed of SSDs which in turn has changed how they’re built and optimized.

Operating systems use SSDs for better indexing, faster search, and more efficient paging. Also today we see that even game engines and creative tools are designed to stream assets directly from fast storage which in turn reduces the need to load everything into RAM at startup.

This has seen a transformation in system architecture. In high performance computing and enterprise settings we use SSDs for caching, tiered storage, and real time analytics which require speed.

SSDs in Everyday Life

From everyday users to professionals, we have all experienced the improved performance which you get from switching out of an HDD to an SSD.

For students we see improved access to research and for photographers and videographers there is smooth editing of large media files. For gamers we have eliminated long load times and stuttering. For businesses we report increased productivity across the board.

In smartphones and tablets the same memory principles of flash that we take for granted today play a role.

Data Centers and the Cloud

SSDs have transformed cloud computing and data centers, where thousands of operations per second are the norm. We see SSDs’ input output operations per second (IOPS) which allow them to keep up.

Tasks such as running virtual machines, managing large databases, and delivering streaming content benefit from what SSDs have to offer in terms of speed and reliability. Also we see that many cloud providers are now presenting SSD backed storage as the default which in turn improves end user experience.

With the help of NVMe over Fabrics (NVMe-oF) technologies, we see SSD performance expanded across the network, which in turn is enabling faster remote storage and disaggregated infrastructure.

The Shift in Consumer Mindset

Performance began to matter more than storage size.

Users started to go for speed and responsiveness which in turn saw the decline of huge amounts of unused space. This in turn brought about new storage solutions like the use of a small SSD for OS and large HDD for archiving also which in turn made it easier for people to determine their true storage requirements.

Today we see that many budget laptops include SSDs as standard due to the large difference in performance that it brings. We have come to expect speed out of the base model, not a high end upgrade.

Looking Ahead

The evolution of SSDs is just getting started. We see in 3D NAND and the growth of NVMe great things to come which will see SSDs become even faster and also more affordable. Also we are at a point where SSD capacities are equal to that of HDDs but we aren’t seeing the performance tradeoff.

Also at play are new storage interfaces and form factors which are pushing boundaries. We see wide adoption of M.2 and U.2 drives and in the pipeline are technologies like PCIe 5.0 and storage class memory (SCM) which will do away with the distinction between RAM and SSD.

Final Thought

SSDs’ entry into the market was a game changer, not just a simple storage upgrade. They transformed how we design computers, what we do with them, and our expectations from them.

Whether at the task of creating a basic document or producing a 4K video, what you notice is the change an SSD brings from slow to smooth. It’s tough to go back to the old days of the spinning drives and slow boot times once you’ve felt the difference.

In many respects SSDs transformed beyond what was expected in computing — they also helped to reinvent what modern computing is.
