SSD storage

What is SSD storage?

Do you know the difference between an SSD and an HDD? Understanding how SSDs store your data and why they’re faster can be crucial for optimizing your storage infrastructure. In this article, we’ll cover everything you need to know about Solid State Drives, how they fit into your storage solutions, and why they’re an excellent way to improve your computer’s performance.

Key takeaways

• SSD stands for ‘Solid State Drive’
• SSDs rely on ‘flash-memory chips’ to store data
• SSDs are efficient, durable, and don’t require a constant power source to store data

What is a Solid State Drive?

A Solid State Drive (SSD), also referred to as a ‘semiconductor storage device’ or ‘solid-state device,’ is a modern secondary storage device for computers.

SSDs are recognized for their compact size, power efficiency, durability, and high-speed access and retrieval times.

How do SDDs work?

SDDs perform the same function as conventional hard drives, but much faster. Let’s take a look at how SSDs actually work to understand why.

SSDs have no mechanical moving parts. Instead, most SSDs store data on flash-memory chips. similar to RAM (random access memory).

These flash-memory chips are known as ‘NAND’ and are arranged in grids or blocks. SSDs differ depending on the number of bits that can be stored in each chip or ‘cell’. You’ll see mention of single-bit up to two, three or four-bit cells, which can hold between 1 – 4 bits of data. Single-bit cells are the most reliable, durable, and fast, but come with a higher price tag.

The SSD’s controller or ‘processor’ is the key component in managing the write/read functions of your storage device. An SSD’s quick access times are thanks to the controller.

Flash-memory SSDs are non-volatile, meaning they continue to store data even when there is no power source. SSDs tend to be smaller and more compact, which means that they are also highly compatible with more portable devices like laptops or tablets.

Overall, the speed of SSDs makes them a top choice for organizations that need to minimize delays when booting up applications or transferring large amounts of data.

What is an SSD interface?

The interface that connects the SSD to your computer significantly impacts the speed of data transfer. An SSD’s interface determines how much data can be transmitted in a given time period (this is called ‘bandwidth’), as well as how much delay you experience between the request for data being sent out and the data actually being transferred (‘latency’).

SSDs with PCIe interfaces deliver the fastest speeds due to the multiple data transfer channels offered by PCIe.

How do HDDs work?

In contrast to SSDs, HDDs use spinning disks or ‘platters’ to read and write your data. The speed of an HDD depends on how many rotations these disks can make every minute. HDDs have ‘heads’ or ‘transducers’ that read and write your data.

Compared to SSDs, HDDs are mechanical, with multiple moving parts working together to store, retrieve, and modify your data. For this reason, they are typically less efficient when locating and retrieving data. Plus, the delicate moving parts make HDDs more vulnerable to damage if they’re dropped or roughly handled.

SSD vs HDD: What are the key differences?

Although they perform the same function, SSDs and HDDs are quite different. Here’s a quick breakdown:

• SDDs rely on newer technology than HDDs
• SDDs boast quicker access times and lower latency than HDDs
  It can be tricky to find larger capacity SSDs compared to HDDs
• SDDs do not need a constant power source to store data
• SSDs use flash-based memory versus HDDs which use spinning disks or ‘platters’
• SDDs are typically more resistant to damage or rough handling
• SDDs run more quietly, vibrate less, and are lighter and more compact than HDDs
• SDDs tend to be more expensive than HDDs
• SSDs may degrade with usage over time

Who uses SSDs?

SSDs and HDDs store data in different ways. Both have their unique advantages and disadvantages, and their suitability depends on the environment and user. SSDs are a reliable way to help speed up your computer, making them an excellent solution for slow-running desktops.

SSDs are particularly useful for businesses and enterprises. Organizations that handle large amounts of data need storage solutions that offer high speeds, reliability, efficiency, and performance. Plus, the durability of SSDs and their ability to store data without power help protect sensitive data from being lost through physical damage or power cuts. Additionally, SSDs boast near-instantaneous access times, meaning, for example, that file transfers can be completed rapidly.

That being said, it’s important to know that NAND Flash-based SSDs leak charge over time if they’re disconnected from power for a long time. This makes them suitable for active use, but not ideal for archival storage. Additionally, the higher capacity of HDDs (at a lower price) makes them a more attractive option in certain use cases.

The future of SSDs

SDDs haven’t completely taken over the market just yet. And with cloud-based storage on the rise, they might not. That being said, local storage is likely to always play an important role to some extent, and as SDDs become more common, prices will be driven down. Their reliability, speed, efficiency, and durability make SSDs preferable for large organizations with significant data storage needs. To stay ahead in data storage solutions, MSPs should know their SDDs from their HDDs.
